【摘要】：为了提高SISI304不锈钢表面特性,通过SEM、辉光放电光谱仪和磨损测试机研究了矿用SISI304不锈钢表面Cu-N渗镀层的组织、元素含量和磨损特性。结果表明:Cu-N渗镀处理后,不锈钢表层生成了一层致密连续的复合渗镀层,渗层上未出现明显的裂纹或孔洞,形成了整齐致密的表面结构。Cu-N渗镀层包含了Cu沉积层与扩散层两部分,两层间具有明显分界。基体存在明显较宽与较深的磨损痕迹,同时在滑动方向上生成了黑色粘附物。Cu-N共沉积后,生成了由小颗粒物组成的具有高硬度的致密渗层,磨损方式为磨粒磨损。生成的S相层对犁沟变形产生了明显的抑制作用。
[Abstract]:In order to improve the surface characteristics of SISI304 stainless steel, the microstructure, element content and wear characteristics of Cu-N coating on SISI304 stainless steel surface were studied by means of SEM, glow discharge spectrometer and wear tester. The results showed that a dense and continuous composite coating was formed on the surface of stainless steel after wee Cu-N infiltration plating, and there were no obvious cracks or holes in the coating. A neat and compact surface structure. Cu-N coating consists of Cu deposit layer and diffusion layer, and there is an obvious boundary between the two layers. There are obvious wide and deep wear traces in the matrix. After codeposition of black adhesives. Cu-N in the sliding direction, a dense layer with high hardness is formed, which consists of small particles. The wear mode is abrasive wear. The formation of S phase layer has an obvious inhibitory effect on ploughing deformation.
