Electroplating enhances the durability of metal components, giving them the resilience to handle even the most corrosive or high-friction environments. While a variety of coating metals might be used, metal and chrome are the most common for industrial applications. Below are a few key differences between nickel and hard chrome plating.

Hard Chrome Plating

Most people associate chrome plating with brightly polished auto parts and appliances, but a thick layer can also provide protection from friction, heat, and corrosion.

Hard chrome plating involves submerging the part in an electrolyte solution containing chromium. When a mild electrical current runs through the liquid, chromium bonds with the surface, creating an even, extremely hard protective layer.

Hard chrome plating is extremely resilient and durable, making it ideal for use in the automotive and aerospace industries. Carmakers often plate pistons and shock absorbers in hard chrome, while aircraft manufacturers use it to protect landing gear and other high-friction components.

Materials treated with hard chrome are also more resistant to corrosion and harsh chemicals. It’s often used in machine shops to protect saw blades, cutting tools, and a wide variety of other precision equipment.

Nickel Plating

Nickel plating still uses electricity to bond the material to the surface, just like chrome plating. This creates a somewhat smoother surface, which may be best for applications that require a high degree of luster or shine.

While not as hard as chrome, nickel-plated surfaces are still relatively durable, so it’s also commonly used in the automotive, aircraft, and manufacturing industries that require that high degree of luster and shine.

Depending on the solution used, nickel may also offer a slightly better corrosion resistance, so it’s often chosen to fortify equipment that will be used underwater or in high-pressure environments.
