Corrosion resistance combined the tribology, new species of pvd and pacvd coating

摘要

As for this invention, conservation from wear and corrosion was improved, it regards the coat system on the substrate. In accordance with this invention, the substrate coat is done at diamond like carbon (DLC) formation. The pin hole of DLC formation is closed this DLC formation, by coat doing at the further formation which uses the material which differs from the DLC coat material.
