What Is Hard Chrome Plating Used For?

Hard chrome plating is the electrochemical process of adding a layer of chrome to metal parts. While hard chrome plating can be used to create a more aesthetic finish, it is also ideal for extending the lifespan of metal components. 

Hard chrome plating offers many benefits, like improving the hardness, durability, and wear resistance of a metal surface. As a result, the metal parts are able to last much longer than they would without the plating process. 

The process of hard chrome plating involves dipping a metal part into a plating bath of dissolved chromium. An electric current is then applied to extract the chromium from the bath and deposit it onto the surface of the metal part in an even layer. After the chromium cures, the plating becomes a sealant that protects the metal part from all types of wear. 

Five Benefits of Hard Chrome Plating

1: Corrosion Resistance

One of the main attributes of hard chrome plating is its ability to improve corrosion resistance. The protective layer of chromium shields the metal from oxidation, preventing rust. Hard chrome plating is ideal for metal parts that are frequently exposed to humid air, and it is often used in the aerospace and defense industries. 

2: Improves Durability

Hard chrome plating improves the durability of the metal surface and protects against all types of wear. The hard layer of chromium can protect metal components from extreme weather and temperatures, and even shields it from impact damage. 

3: Enhances Appearance

The hard chrome plating process leaves a smooth, attractive finish. Hard chrome plating can even restore an old metal part&#;s appearance by removing faults to make it look brand new. In addition to enhancing appearance, it also makes metal surfaces easier to clean.

4: Reduces Friction

Hard chrome plating is an ideal treatment for moving metal parts, because it helps reduce friction. Low friction allows for more efficient moving parts and extends the life of the individual metal parts. It also reduces the risk of metal parts overheating, galling, or seizing. 

5: Versatile Applications

Hard chrome plating can also be applied to many different types of metals, such as copper, stainless steel, aluminum, brass, and titanium. Because of the many benefits it provides, hard chrome plating is used for a wide variety of applications.

The Difference Between Hard Chrome and Decorative Chrome Finishes

The primary difference between decorative chrome and hard chrome plating is the thickness of the chrome plating on the final product. Decorative chrome plating is thinner than hard chrome and is primarily for aesthetic appeal and as a protective coating. Hard chrome plating is thicker than decorative chrome finishes and is useful in many industrial applications for its strength, wear resistance, corrosion resistance and other beneficial properties.

Decorative chrome and hard chrome plating result from the same chrome manufacturing process but differ in their final properties and common applications. Chrome plating uses an electrolytic process that applies chromium plating to a metal component in an electrolytic bath at a rate of about 25 to 30 microns per hour. The substrate first gets cleaned thoroughly and, if necessary, treated with chemicals to improve the adhesion of the plating. The component then goes into a chrome plating vat for chrome dipping, where an electric current deposits chromium onto the substrate.

The electrolytic process and chrome dipping apply both types of chrome plating evenly to components of unusual shapes, sizes and textures. Hard and decorative chrome plating can adhere effectively to ridged or flat surfaces, in small holes or recesses and to cylindrical parts. With a large enough plating vat, you can apply chrome plating to metal components of nearly any size. The versatility of chrome plating makes it a popular chrome finishing choice for a wide range of applications in manufacturing and consumer goods.

What Is Hard Chrome Plating Used For?

A variety of industrial applications use hard chrome plating to increase the wear and corrosion resistance of equipment components. Also known as engineered chrome or industrial chrome, hard chrome plating reduces friction between machine parts and improves component durability. A hard chrome coating extends the lifespan of machine components and reduces maintenance downtime and expenses.

Hard chrome plating can also be useful in repairing damaged, worn or mis-machined parts. A component that is too small or has become worn down can benefit from applying a thick coating of hard chrome plating to return it to the correct dimensions. Stripping the damaged plating through a chemical process and applying new hard chrome plating can repair a damaged part.

Hard chrome plating can apply to a wide variety of base metals to strengthen an equipment component without compromising its original properties. Base metals that chrome plating can be applied to include: steel, stainless steel, copper, brass, bronze, and more. Depending on the specific purpose, hard chrome plating can vary widely in thickness to meet precise project needs. The strength and durability of hard chrome plating make it extremely beneficial in a variety of applications, such as:

• Hydraulic cylinders

Manufacturers of hard chrome plating can polish it to superior smoothness for rounded components like print cylinders and rollers, while still providing exceptional resistance to wear when used with abrasive products like textiles, paper, limestone or sand.

Hard chrome is also easy to clean and sanitize, making it a popular choice for the food and beverage processing industry. The superior corrosion resistance of hard chrome plating makes it effective in pharmaceutical, chemical and oil and gas applications as well. Other industries where you can see hard chrome plating at work include printing, textiles, mining, agriculture, paper, manufacturing and many others.

What Is Decorative Chrome Plating Used For?

Decorative chrome plating has more limited applications than hard chrome plating, but serves an essential role in many industries. Although it does not offer the same strength and durability as hard chrome, decorative chrome finishes can still provide a thin protective coating when applied to automobile parts, tools and utensils. Decorative chrome finishes protects against rust and wear when products get exposed to wet or corrosive conditions.

Decorative chrome plating also provides a smooth and shiny appearance that is easy to clean, making it desirable for various consumer products. If used solely for aesthetic appeal, decorative chrome plating is sometimes applied using inexpensive imitation chrome finishes instead of actual chromium. Here are a few common applications of decorative chrome plating.

• Car parts: Decorative chrome plating is a feature of many car parts such as bumpers, trim, rocker panels, door handles and grills. Applying decorative chrome plating increases the corrosion resistance of these parts so they will not rust when exposed to rain or snow. Decorative chrome also allows various finishing and buffing options to increase its shine and aesthetic appeal.
• Tools: Many tools and hardware &#; such as wrenches, pliers, sockets and hex keys &#; get finished with decorative chrome plating to improve their durability and wear resistance. Tools with chrome plating are suitable for use in harsh environments without damage.
• Kitchen utensils: Decorative chrome plating can apply to metal kitchen utensils &#; such as spatulas, tongs, knives, spoons and forks &#; to increase their corrosion and heat resistance. Kitchen utensils with chrome plating are easy to clean and provide durability for long-term use. Shiny chrome kitchen utensils also offer aesthetic appeal for home cooks and chefs alike.
• Musical instrument hardware: Hardware for guitars, clarinets and other musical instruments sometimes receive a thin coating of decorative chrome plating for enhanced appearance and durability.

You might hear people call decorative chrome plating nickel-chrome plating, as it gets applied over nickel plating, rather than directly to the metal substrate. In some applications, copper plating also gets first to improve the strength of the final product. Decorative chrome plating is very thin compared to more durable hard chrome plating, typically measuring just a few millionths of a meter.

What Is Hard Chrome Plating?

Hard chrome plating is an electroplating process that involves applying a layer of chromium to a surface by submerging it in a chromic acid solution. Hard chrome plating can increase the durability, hardness, wear resistance and corrosion resistance of metal components for more effective use in machinery and equipment. It is possible to apply chrome plating without altering the properties of the original component, and deposit it in the precise thickness necessary for a specific application. Hard chrome plating creates a surface that is very hard (68-72 Rockwell C), highly wear and corrosion resistant, has a low coefficient of friction, and very smooth and easy to clean. Here are some of the benefits of hard chrome plating and the desirable properties it offers.

• Superior hardness: Hard chrome plating is harder than most other industrial abrasives and metallic coatings. Measuring between 68 and 72 HRC, hard chrome plating can withstand demanding industrial applications and high stresses. Although decorative chrome plating technically possesses the same hardness as hard chrome plating &#; because it gets engineered with the same material and manufacturing process &#; decorative chrome is so thin it does not exhibit the same hardness properties in actual use.
• Durable thickness: Depending on the specific application, it is possible to apply hard chrome plating in various thicknesses to meet the project needs. Hard chrome plating between 10 and 500 micrometers will provide a hardness of about 68 to 69 HRC. Thick, hard chrome plating protects machine components against wear during regular operation or in harsh conditions, such as when exposed to corrosive chemicals. When used to repair damaged or worn components, manufacturers can apply hard chrome plating much thicker if necessary. It offers excellent resistance to abrasion and wear to extend component lifespan.

• Low deposition temperature: Applying hard chrome plating at low temperatures ensures the physical and mechanical properties of the substrate remain unaffected during the plating process. It is possible to deposit hard chrome plating without the risk of damaging precise metal parts and equipment components.
• Wide range of bases: Hard chrome plating can apply to a wide range of base metals to suit various industrial applications. Hard chrome plating often gets applied to stainless steel and other high-alloyed steels, as well as to alloys of copper, aluminum, titanium, bronze, brass and nickel. This flexibility makes hard chrome plating useful in many different industries, from food processing to automobile manufacturing.
• Excellent adhesion: Offering long-term durability, hard chrome plating has excellent adherence to many metal bases with minimal risk of flaking. To further improve adhesion, components get cleaned thoroughly to remove all contaminants before plating. Parts get treated with chemical solutions as necessary to ensure strong and lasting adherence of the chrome plating during the electrolytic bath.
• Low friction: Hard chrome plating creates very little friction when in contact with metals, graphites, carbons and polymers. When used on moving parts, hard chrome plating reduces friction and heat between equipment components. Lower friction and reduced operating temperatures can prevent parts from seizing and extend the lifespan of essential equipment components like pumps and hydraulic cylinders. The low friction and superior smoothness of polished hard chrome plating also ensure sensitive products do not get damaged from abrasion during processing.
• Wear and abrasion resistance: Because of its hardness and low friction, hard chrome plating is exceptionally resistant to wear. Hard chrome plating can be applicable to sliding components, in metal-to-metal contact applications and with rough, abrasive products like coal, sand and cement. Even in high mechanical contact stress, hard chrome plating holds up against wear and abrasion for long-term durability.
• Corrosion resistance: Hard chrome plating has extreme oxidization resistance, making it invaluable in the chemical, pharmaceutical and food and beverage industries. You can use hard chrome plating with most gases and organic acids for processing materials like fruits, beer, brines, milk, oils and fuels, molten glass and glue. Because they can withstand harsh sanitizers and cleaning agents, it is possible to thoroughly clean hard chrome-plated machine components for applications where sanitation is crucial.

• Easy re-plating: If hard chrome plating does become damaged or eventually wears down over time, it is easy to remove with stripping chemicals and replace with fresh plating. You can strip old hard chrome plating without harming the substrate, allowing repeated re-plating to greatly extend the lifecycle of equipment components. Re-plating components with hard chrome reduces costs associated with replacing parts, which is especially beneficial for customized parts or difficult-to-acquire components.
• Variety of chrome finishing options: Hard chrome permits various finishing options including grinding and polishing. You can apply thick hard chrome plating, then precisely grind it down to meet exact dimensions for parts. It is also possible to polish hard chrome to exceptional smoothness for applications that require very low friction and abrasion. For applications when aesthetic appeal is a concern, manufacturers of industrial chrome plating can polish and shine it for the same attractive look as decorative chrome.

These benefits of commercial chrome plating can enhance the existing properties of metal components for more effective use in many industrial applications. Companies can maximize the beneficial properties of their hard chrome plating by adjusting the thickness of the plating for increased hardness and durability. Through different chrome finishing techniques, hard chrome plating can provide the precise benefits a project requires.

What Is Decorative Chrome Plating?

Decorative chrome plating is primarily an aesthetic feature, though it also protects against corrosion and wear. However, because decorative chrome is so thin &#; ranging from about five to eight micrometers when applied over nickel plating &#; it does not offer as much durability as hard chrome plating. If you find yourself asking, "How long does decorative chrome plating last?" you should be aware that it can wear off over time. Here are the primary benefits of decorative chrome plating.

• Improved appearance: Decorative chrome plating provides an appealing shine and smooth, sleek surface. When used for consumer goods like kitchen utensils and tools, decorative chrome plating can increase their perceived value. Shiny chrome plating also makes cars and musical instruments more attractive.
• Corrosion resistance: Decorative chrome plating protects products from corrosion due to chemicals or other oxidizing agents. This protective layer is particularly beneficial when using decorative chrome plating for car parts or other products intended for use outdoors or in wet environments.
• Easy cleaning: Due to its corrosion resistance, decorative chrome plating is easy to clean with household cleaners and chemicals. Its smooth surface also does not trap dirt and dust particles, so products with decorative chrome plating can continue to shine for long-term use.
• Some wear resistance: Decorative chrome plating can increase the strength of a product to some degree. However, because it is so thin, it is also fairly easy to damage. For example, decorative chrome plating on a bumper can get cracked in a car accident, exposing the metal underneath to corrosion and rust. Chrome-plated kitchen utensils can also degrade over time as the thin chrome layer wears off.

For applications where aesthetics and function are essential, decorative chrome plating can work well. Attractive and corrosion-resistant decorative chrome can enhance many consumer goods.

Which Plating Method Is Right for You?

Decorative chrome plating offers exceptional aesthetic appeal, while hard chrome plating provides superior strength and hardness, low friction and lasting durability. Both types of chrome plating are useful for different applications, and the best plating method for you will depend on your unique project needs. For consumer goods, decorative chrome plating can provide the necessary protection and desired appearance, while hard chrome plating is better-suited for high-stress industrial applications.
