Abstract

This paper investigates the effect of SAE grade 20W50 engine oil as a lubricant on the wear behaviour of chromium nitride (CrN) coating deposited by PVD process at higher loads and speeds by pin on disc tribometer. The specific wear rate ranges from 9.82 × 10-5 to 2.87 × 10-5 mm3/Nm in dry condition whereas in lubricated condition 0.97 × 10-5 to 0.19 × 10-5 mm3/Nm. Successive increase of speed and load rises the temperature of wear track from 65°C to 178°C in dry condition while 34°C to 40°C in lubricated conditions results to decrease in friction coefficient, which has immense influence on the wear resistance of coating. The wear mechanism of the coatings was analysed by SEM and EDS and found deformation, cracks and, nitride particle pull-out, built up edge formation, erosion and adhesive wear coupled with oxidation wear. The highlights of the paper are: 1) tribology of CrN coating against cylinder liner material as counter face summarised; 2) research has practical applications for piston ring with the influence of engine oil; 3) temperature ranges from 65°C to 178°C in dry and 34°C to 39°C in lubrication during wear test; 4) the wear mechanism is combination of three body abrasion, metal transfer and oxidation.

润滑对PVD沉积CrN涂层磨损性能的影响

采用针盘式摩擦计研究了SAE级20W50机油作为润滑剂对PVD工艺沉积的氮化铬(CrN)涂层在高载荷和高转速下磨损性能的影响。干燥工况下的比磨损率为9.82 × 10-5 ~ 2.87 × 10-5 mm3/Nm，润滑工况下的比磨损率为0.97 × 10-5 ~ 0.19 × 10-5 mm3/Nm。随着转速和载荷的不断增加，干燥工况下磨损轨迹温度从65℃上升到178℃，润滑工况下摩擦系数从34℃上升到40℃，摩擦系数下降，对涂层的耐磨性有较大影响。利用扫描电镜和能谱分析了涂层的磨损机理，发现了涂层的变形、裂纹和氮化物颗粒的脱落、边缘的形成、侵蚀和氧化磨损。本文的重点是:1)总结了CrN涂层与缸套材料作为反端面的摩擦学特性;2)研究具有实际应用价值的活塞环对机油的影响;3)磨损试验时，干燥温度范围为65℃~ 178℃，润滑温度范围为34℃~ 39℃;4)磨损机理是三体磨损、金属转移和氧化的结合。
