Summary: Thin film hard and wear resistant coatings were deposited by Electron Beam Evaporation, Sputtering, Cathodic Arc Deposition and Plasma Assisted CVD (Chemical Vapor Deposition) by commonly used industrial suppliers. Coating mechanical properties are reported. Results show that most industrial coating companies are producing coatings with high levels of adhesion and good mechanical and tribological properties. The effect of coatings on corrosion resistance was investigated by salt fog testing and exposure to PFPAE (Perfluoropolyalkylether) at elevated temperatures.
