|
Abstract:
本文采用激光熔覆技术将CoNiCuMn0.8Si0.2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CoNiCuMn0.8Si0.2高熵合金熔覆层的微观组织、硬度及耐磨性能。结果表明，熔覆层均与Dp780双相钢具有清晰的融合线，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，且硬度值达到了460 HV。
In this paper, CoNiCuMn0.8Si0.2 high entropy alloy powder was cladded on Dp780 dual phase steel substrate by laser cladding technology. The microstructure, hardness and wear resistance of CoNiCuMn0.8Si0.2 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.
