中文摘要: 采用激光熔覆工艺， 在试样表面制备了不同碳含量的不锈钢熔覆层， 并对其组织结构、 耐磨及耐腐蚀性能
进行了研究。 结果表明： 不锈钢合金粉末中碳含量由 0.05 wt.% 提高至 0.2 wt.% 时， 熔覆层中 γ-Fe 相逐渐增多，
α-Fe 相逐渐减小。 对于熔覆层性能方面， 碳元素含量的增加有利于提高熔覆层的硬度和耐磨性能， 但会降低熔覆
层的耐蚀性能。
Abstract:Stainless steel cladding layer with different carbon content was prepared by laser cladding process.
The microstructure, wear-resistance and corrosion-resistance were investigated. The results showed that when the
carbon content in stainless steel alloy powder increased from 0.05 wt.% to 0.2 wt.%. the γ-Fe phase in cladding
layer increased gradually, while, the α-Fe phase decreased gradually. For the properties of cladding layer, the
increase of carbon element content is helpful to improve the hardness and wear-resistance of cladding layer, but
may reduce the corrosion-resistance of cladding layer.
