摘要

Physical vapor deposition (PVD) includes vacuum evaporation, sputtering and ion plating. PVD processes are used to apply functional hard coatings and decorative thin films. The most widely used coating is titanium nitride (TiN). other coatings successfully commercialized include titanium carbonitride (TiCN), chromium carbide (CrC), chromium nitride (CrN), zirconium nitride (ZrN), and titanium aluminum nitride (TiAlN). PVD coatings are very hard, have a low coefficient of friction, are chemically resistant and environmentally safe. When applied to different components, they act as chemical and thermal barriers. Coating applications for TiN include cutting and forming tools, plastic molds, surgical instruments and prostheses. CrC and CrN can be a direct replacement for chromium plating for decorative applications, such as watch components, eyeglass frames, pen components, door and window hardware and plumbing fixtures. PVD coating processes, properties of coatings and commercialized applications are reviewed here.
