%X 本文采用激光熔覆技术将CoNiCuMn<sub>0.8</sub>Si<sub>0.2</sub>高熵合金粉末熔覆于Dp780双相钢基体上。在最优熔覆参数下研究了CoNiCuMn<sub>0.8</sub>Si<sub>0.2</sub>高熵合金熔覆层的微观组织、硬度及耐磨性能。结果表明&#65292;熔覆层均与Dp780双相钢具有清晰的融合线&#65292;其组织形貌主要以白色胞状晶及黑色圆点状组织嵌于基体中。高熵合金涂层显著提升了Dp780双相钢基体的硬度及耐磨性&#65292;且硬度值达到了460 HV。<br>In this paper, CoNiCuMn<sub>0.8</sub>Si<sub>0.2</sub> high entropy alloy powder was cladded on Dp780 dual phase steel substrate by laser cladding technology. The microstructure, hardness and wear resistance of CoNiCuMn<sub>0.8</sub>Si<sub>0.2</sub> high entropy alloy cladding layer were studied under the optimal cladding parameters. The results show that the cladding layer has a clear fusion line with Dp780 dual-phase steel, and its microstructure is mainly white cellular crystal and black dot-like structure embedded in the matrix. The high-entropy alloy coating significantly improves the hardness and wear resistance of the Dp780 dual-phase steel substrate, and the hardness value reaches 460 HV.
