Research Progress of Nitride Coating Process Prepared by Cathodic Arc Ion Plating

As the main process of carbide tool coating fabrication, cathodic arc ion plating plays an important role in modern industrial production. This paper introduces the influence of process parameter selection on the coating properties of tools by cathodic arc ion plating. The process parameters mainly include nitrogen partial pressure, negative bias pressure and arc current, and the coating properties are mainly characterized by deposition rate, phase composition, coating hardness and surface quality. It can optimize the selection of process parameters on modern industrial production.
