CrN
CrN is characterised by its good corrosion resistance, which is comparable with that of hard chrome plating, yet demonstrating significantly greater bonding strength and hardness. As the coating is very easy to polish, a particularly dense and smooth surface can be achieved.
CrN is the best metallic coating for injection moulding of plastics and in delicate applications. CrN coated components often demonstrate better demoulding behaviour than that of other low-friction coatings. CrN is also very well-suited for mould coating in the processing of special metals such as copper, brass, bronze, nickel silver, galvanised or tin-plated sheet steel. CrN is also proven effective for die casting aluminium, zinc, as well as in warm forming of steel and brass.
