摘要：

In this paper, CrMnFeCoNiMo high entropy alloy coating was prepared on 304 stainless steel by plasma cladding technology. The effects of different heat treatment processes on the microstructure, hardness, wear resistance and corrosion resistance of high entropy alloy coatings were studied. The XRD and SEM images of the coating show that the phase structure is mainly Ni-Cr-Co-Mo phase. The impurity phase-[CrFe] solid solution and Ni3Fe phase will be formed between 950 degrees C and 1050 degrees C. The homogenization effect of the coating composition is more excellent under the heat treatment conditions of 950 degrees C and more than 1 h holding time. The hardness of the coating is relatively high at 850 degrees C heat treatment temperature and holding for 1 h, which is 670 HV0.2. When the temperature rises to 950 degrees C and 1050 degrees C, the hardness of the coating decreases. The coating has relatively high wear resistance at 950 degrees C heat treatment temperature and holding for 1 h, and the friction coefficient is about 0.27. Moreover, under this heat treatment condition, the surface composition of the coating is uniform and the corrosion resistance is good. The self -corrosion current is 1.325 x 10-7 A and the self -corrosion potential is -0.202 V.
