The PVD process is defined as the creation of vapors in a vacuum from solid material sources and their subsequent condensation onto a substrate. The equipment in use at Chrisbo is based on the  Cathodic Arc Vapor Deposition method. In this method the source metal is simultaneously evaporated in microscopically small areas and the vapor particles are ionized and accelerated all in one single work stage. The Arc PVD process used by CHRISBO offers the highest degree of ionization and the highest average ion energy. This is why coatings deposited at temperatures of  200^oC are characterized by good adhesion.

The PVD process advantages versus the CVD process:

1. The PVD process is conducted at lower temperatures (180^oC to 500^oC). The low PVD processing temperatures mean that nearly all tool materials can be coated without concern for softening or distortion.
2. The PVD process does not use any hazardous materials which makes the process environmentally friendly.
3. The PVD process is highly energy  efficient.
4. The high degree of ion energy ensures excellent adhesion.
