Tungsten Carbide Insert Coating Issues

For coated tungsten carbide insert,the main coating issues related to machining of steel , stainless steels or cast iron and other milling operations are delamination or cracking of the protective coating.

It is known that, during machining, the cutting edges of tungsten carbide insert are worn because of different wear mechanism such as, chemical wear, abrasive wear and adhesive wear. In addition, if the cutting speed is high, there will be a considerable amount of heat occurs in cutting zone and a plastic deformation is likely to generate, which for a payback, an enhanced wear will be triggered as a consequence of delamination or coating cracking.
