What is P-CVD?

CVD is defined as ‘a surface hardening by thermochemical diffusion penetration’ and it greatly increase wear-resistance, corrosion-resistance & thermal resistance. This is not a simple coating on the material surface, but a surface penetration with CVD method. So, the P-CVD treated material has no flaking which usually takes place in the general coated material such as stellite coating, tungsten carbide coating, chrome carbide coating and so on.
