Corrosion resistance and corrosion fatigue strength of carbon steel coated with chromium nitride by multistage PVD method

摘要

Chromium nitride(CrN) exhibits good corrosion resistance in addition to excellent electrical and mechanical properties. A decrease in the number of defects such as pinholes or voids formed during deposition is required for improvement of corrosion resistance and corrosion fatigue strength of coated materials. A multistage physical vapor deposition(PVD) method was proposed in order to fabricate dense thin-coating films.
