在MFT-R4000摩擦磨损试验机上考察了几种固体润滑层的减摩抗磨性能,并利用电化学工作站研究了其腐蚀电流和腐蚀电位的变化情况,分析了磨损表面的形貌和硫元素的化学价态变化。几种改性表面的耐腐蚀性能从好到坏的顺序为:NSL层>SLD层>离子渗硫>基体;抗磨性能从好到坏的顺序为:NSL层>SLD层>离子渗硫>基体;摩擦因数从大到小的顺序为:基体>离子渗硫>SLD层>NSL层。NSL层的耐腐蚀性能和抗磨减摩性能最好,原因主要是基础油和纳米材料的润滑作用和屏蔽作用。
The antifriction and antiwear properties of several solid lubricating layers were investigated on a MFT-R4000 friction and wear tester. The corrosion current and corrosion potential of the samples were investigated by electrochemical workstation. The morphology of the worn surface and the content of sulfur Chemical valence changes. The order of corrosion resistance of several modified surfaces from good to bad is: NSL layer> SLD layer> ion infiltration sulfur> matrix; the order of anti-wear performance from good to bad is: NSL layer> SLD layer> ion infiltration sulfur> Matrix; the order of friction coefficient from large to small is: matrix> ionized sulfur infiltration> SLD layer> NSL layer. NSL layer corrosion resistance and antifriction and antifriction performance is best, mainly due to the lubricating oil base and nano-materials and shielding effect.
