During the machining operations , the chemical vapour deposition (CVD) coatings as a traditional way have been widely applied in tungsten carbide inserts to enhance the tool life. Only in USA and Europe, there are over 60% of the cutting tools are applied by the CVD process.

However, the CVD coatings due to inherent disadvantages, have been examined several limitations which include the relative higher deposition temperature (950~1050℃） compared Carbide Turning Inserts to other coating method, tensile stresses increasing between layers,  inability to achieve thin coating layers as well as multicomponent coating layers, and due to the brittle formation, sometimes the adhesion of coating to the substrate is poor.
