What Is Hard Chrome Plating Used For?

Individuals apply hard chrome plating to a variety of metal substrates in order to reduce friction, improve abrasion tolerance, increase resistance to oxidation and prolong the wear of the piece. People can also use it with the purpose of restoring the girth of a worn piece to its original dimensions.

It is possible to apply hard chrome to high-alloyed steel, stainless steel, brass, bronze, cast iron, lightweight aluminum alloys, titanium alloys, copper alloys and nickel-based alloys. The application results in a finished piece that is resistant to abrasion even under high contact stress. Wear rates are lower than that of hardened steel. When applied in thicker layers, hard chrome also offers wear resistance from high stress contact with sand, limestone, coal and glass fibers.

You can apply hard chrome to a wide range of geometric shapes, including large flat surfaces, bores, cylinders and precision pieces with close tolerance areas. Grinding and polishing leads to a level of finishing that yields surfaces that are suitable for contact with delicate materials. The low metal-to-metal wear resistance levels obtained make it ideal for pieces requiring dry sliding contact, such as lathe beds.

The stable chemical properties of hard chrome make it highly resistant against corrosion to organic acids. It is suitable for applications involving contact with a wide variety foodstuffs, fuels and cyanides.
