摘要
The 42CrMo4 steel is a material popularly used in weapon manufacture. This article that deals with improving wear resistance of gun components will study tribological behaviour of above steel, treated by plasma nitriding technologies under different condition of duration and gas ratio. The friction coefficient and wear rate were investigated using the wear test based on principle "ball on disc". The results were supplemented with mechanical properties and metallographic documentations. The results show that plasma nitriding improved dramatically the mechanical properties and wear resistance of materials, and the level of wear resistance was related to the nitriding process parameters.
