摘　　要：为高效研究齿轮油及添加剂对齿面微点蚀影响规律,降低研究初期抗微点蚀齿轮油开发的成本,采用四球试验机、往复摩擦试验机(SRV)及滑滚摩擦试验机(MPR)考察了PAO基础油、由市售高性能复合剂调和的齿轮油以及由通用齿轮油复合剂调和的齿轮油的摩擦学行为与抗微点蚀性能的对应性,并分析MPR试验后辊子表面3种齿轮油对微点蚀造成的影响.试验结果表明:四球机法未能凸显不同添加剂之间的微点蚀差异,SRV试验机在低频重载条件下的摩擦测试结果与3种齿轮油的实际应用中抗微点蚀性能保持一致.此外,MPR滑滚摩擦试验结合辊子表面形貌及元素分析能够有效地区分不同齿轮油的抗微点蚀性能,其中基础油由于较差的润滑,对摩擦副表面起到机械抛光作用使微点蚀面积仅为1.36%,高性能复合剂的添加导致了1.45%的微点蚀面积,优于通用复合剂作用下4.67%的结果,这是由于表面形成了含硼化合物保护膜.对此本文中提出了采用SRV初步评价与MPR相结合的经济高效抗微点蚀性能评价手段.In order to efficiently evaluate the influence of gear oil and additives on micropitting,and minimize the cost associated with early-stage development of anti-micropitting gear oil,a four-ball testing machine,reciprocating friction testing machine(SRV),and sliding and rolling friction testing machine(MPR)were employed.These instruments enabled an examination of the performance of gear oil in terms of its frictional behavior and anti-micropitting capabilities when compared to PAO,PAO with commercially available anti-micropitting additive packages,and PAO with universal additive packages.The effects of these three types of gear oils on micropitting were analyzed post MPR testing.Experimental results indicated that the four-ball machine method did not effectively distinguish the differences in micropitting among the three lubricants.However,the friction test results from the SRV under low-frequency and heavy-load conditions aligned with the anti-micropitting performance of the three types of gear oils in real-world applications,making it beneficial for the efficient evaluation of the tribological properties of additives.Moreover,the MPR sliding-rolling friction test could more accurately simulate the state of micropitting under sliding rolling contact fatigue.By employing a metallographic microscope,SEM,and a 3D profilometer to analyze the friction morphology of the roller surface,it was concluded that the poor lubrication of the base oil had a mechanical polishing effect on the friction pair surface,which suppressed the propagation of cracks and reduced the micropitting area to a mere 1.36%.The inclusion of high-performance composite agents(Gear oil-1)resulted in a micropitting area of 1.45%,which was superior to the 4.67%observed under the action of general composite agents(Gear oil-2).In conjunction with the elemental analysis of additives using ICP and the roller surface using XPS,the combined effect of the boron-containing compound protective film on the friction surface and the sulfur/phosphorus additive was c
