Tungsten Carbide Cutting Tools With Cathodic Arc Deposition Technique

Cathodic arc deposition (Arc-PVD) is recognized as a physical vapor deposition technique. During the evaporation processes ,an electric arc is adopted to vaporize material from a cathode target. The vaporized material then condenses on a substrate, forming a thin film. The technique can be used to deposit metallic.



Cathodic arc deposition technique is actively used to synthesize extremely hard film to protect the surface of tungsten carbide cutting tools and extend their life significantly. A wide variety of thin hard-film, carbide inserts superhard coatings and nanocomposite coatings can be synthesized by this technology including TiN, TiAlN, CrN, ZrN, AlCrTiN and TiAlSiN.
