Preparation of Ni-P-MoS_2 Composite Coating and Study on Its Wear Resistance
Ni-P-MoS2 composite coating was prepared by electro-deposition.The relationship between addition amount of nano-particles in electroplating solution and depositing rate of the coating was studied.The influences of addition amount of nano-particles on micro-hardness and wear resistance were analyzed.The results show that the wear resistance improves when the adding amount of MoS2 is 4 g/L.Wear mass loss of Ni-P-MoS2 composite coating is 55% of normal Ni-P coating.After heat treatment at 400 ℃ for 1 h,Ni-P-MoS2 composite coating shows better wear resistance.
