Plasma instead of chrome - the environmentally friendly alternative

For many years chrome plating has been the solution for certain requirements on surfaces, such as hardness and corrosion resistance. As requirements are getting more and are harder to be met, the environmental impact gains importance too.

A nitrided layer in combination with post oxidation to create a black oxide layer increasingly replaces chrome plating. Especially plasma nitriding is a very environmental friendly process that diffuses nitrogen into the surface to increase wear resistance, fatigue strength and corrosion resistance. With a black oxide layer it results in a smooth and sleek black surface finish, great for applications like hydraulic cylinder bars, all kinds of pistons and many more. On top of that, it has a very aesthetic look and is able to retain lubricants such as oils. In addition a nitrided layer will not peel off, unlike chrome plating.
