Coated Tungsten Carbide Insert Plastic Deformation Resistance(2)

As an alternative option, adding cubic carbides such as TiC, Tac or NbC also could increase the coated tungsten carbide insert plastic deformation resistance. But it should be noticed that it also has a negative effect on edge chipping tendencies.

Since the constitution of the applied wear resistant surface coating is a vital factor in the tool properties, it could also increase the plastic deformation resistant. When adopting chemical vapor deposition , the coating tends to be thicker and more wear resistant, and the insert’s plastic deformation resistant is improved however a larger extent impair edge toughness is likely to occur.
