巴氏合金ZChSnSb 8-8海水环境下的摩擦学行为研究

Tribological Performance of Tin-based White Metal ZChSnSb8-8 under Simulated Sea Water Environment

摘要: 本文研究了巴氏合金ZChSnSb 8-8/AISI 52100轴承钢摩擦副在模拟海水环境下的摩擦学行为。通过扫描电镜(SEM)，X射线能谱仪(EDS)，X射线光电子能谱仪(XPS)和X射线衍射仪(XRD)对试验样品进行表征。结果表明：巴氏合金ZChSnSb 8-8在海水润滑下具有较低的摩擦系数和磨损率，海水作为润滑介质，起到了一定的润滑作用。在海水润滑下，ZChSnSb 8-8的摩擦系数随载荷和滑动速率的增加而减小；磨损率随着载荷的增加而增加，但随着滑动速率的增加而减小。低的摩擦系数和磨损率主要归因于巴氏合金ZChSnSb 8-8独特的微观结构和海水的润滑作用。

Abstract: Tribological behaviors of Babbitt alloy ZChSnSb 8-8 sliding against AISI 52100 stainless steel lubricated by simulated sea water were investigated. The SEM, energy-disperse X-ray spectrometer (EDS), XPS and XRD characterizations were used to understand the corresponding wear mechanism. The results indicated that the friction coefficients decreased with load and sliding speed. The wear rates increased slightly with load but decreased with sliding speed. The low friction coefficient and wear rate can be attributed to the unique structure of ZChSnSb 8-8 and the lubricating effect of sea water.
