Analysis of the wear of forging tools surface layer after hybrid surface treatment

The preliminary results showed that the best effects for the whole tool working surface were obtained for the Cr/CrN layer, characterizing in high adhesion as well as the lowest Young's modulus E and hardness. In the case of high tool forces and the related friction, the best results were obtained for the AlCrTiN coating, which, beside its good adhesion properties, also characterizes in the highest abrasive wear resistance.
