摘要:
在304L不锈钢表面采用激光熔覆法制备了Fe50-xMn30Co10Cr10Nbx(x=0, 5)高熵合金熔覆层,通过添加Nb元素和不添加Nb元素进行对比试验,研究Nb元素对于熔覆层组织和性能的影响。研究表明,采用激光熔覆法制备的高熵合金熔覆层顶部为细小的等轴晶,而靠近基体部分则为柱状晶;Nb元素的加入能够促进Laves相产生,提高了高熵合金熔覆层的硬度和耐磨性,Fe45Mn30Co10Cr10Nb5熔覆层的硬度最高可达357.6HV0.05,约为Fe50Mn30Co10Cr10熔覆层最大硬度的1.2倍,Fe45Mn30Co10Cr10Nb5熔覆层磨损失重相比Fe50Mn30Co10Cr10减少约27%。研究结果可为提高304L不锈钢表面性能提供一定的试验依据。
Abstract:
The cladding layer of Fe50-xMn30Co10Cr10Nbx(x=0, 5) high entropy alloy was prepared by laser cladding on 304L stainless steel. The effect of Nb element on the microstructure and properties of the cladding layer was studied by comparing the addition and non-addition of Nb element. The results show that the cladding layer of high entropy alloy prepared by laser cladding has fine equiaxed crystals at the top and columnar crystals near the matrix. The addition of Nb element can promote the generation of Laves phase and improve the hardness and wear resistance of the cladding layer of high entropy alloy. The hardness of Fe45Mn30Co10Cr10Nb5 is up to 357.6HV0.05, which is about 1.2 times of the maximum hardness value when Nb=0, and the wear weight loss is about 27% less than when Nb=0. The results can provide a certain experimental basis for improving the surface properties of 304L stainless steel.
