Abstract
Physical vapor deposition (PVD) technologies are widely used to produce wear and corrosion resistant coatings for a variety of industrial applications. In recent years, there has been remarkable interest in the development of novel wear resistant coatings prepared through PVD methods, which helps to reduce friction and wear, as a result of recovering energy losses up to 30% due to friction and economy loss due to wear. This chapter provides comprehensive data of recent progress in wear resistant coatings prepared using PVD methods, starting with the introduction of it needs, significance, physiochemical properties, and the selection criteria of wear resistant coatings. The applications, physical, and chemical properties of superhard materials such as diamond like carbon (DLC), titanium nitride (TiN), chromium nitride (CrN), and tantalum nitride (TaN) are also presented.
