【摘要】:為了提高SISI304不銹鋼表面特性,通過SEM、輝光放電光譜儀和磨損測試機研究了礦用SISI304不銹鋼表面Cu-N滲鍍層的組織、元素含量和磨損特性。結果表明:Cu-N滲鍍處理后,不銹鋼表層生成了一層致密連續(xù)的復合滲鍍層,滲層上未出現(xiàn)明顯的裂紋或孔洞,形成了整齊致密的表面結構。Cu-N滲鍍層包含了Cu沉積層與擴散層兩部分,兩層間具有明顯分界。基體存在明顯較寬與較深的磨損痕跡,同時在滑動方向上生成了黑色粘附物。Cu-N共沉積后,生成了由小顆粒物組成的具有高硬度的致密滲層,磨損方式為磨粒磨損。生成的S相層對犁溝變形產生了明顯的抑制作用。
[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.
