摘要/Abstract

摘要： 配制含有不同质量分数抗磨剂和防腐剂的一系列航空润滑油，利用轴承腐蚀模拟评定装置对润滑油试样进行轴承腐蚀模拟实验，并按照腐蚀等级评价标准对实验结果进行量化处理。通过对实验数据的分析，发现抗磨剂和防腐剂均能够对航空润滑油的防腐性能产生影响。对抗磨剂添加前后润滑油的紫外吸光度进行测量，计算出了抗磨剂添加前后航空润滑油界面膜中防腐剂吸附量的变化。将计算结果与抗磨剂添加前后航空润滑油防腐性能的差异进行对比发现，界面膜中防腐剂吸附量的变化量与航空润滑油防腐蚀效果的变化一致，表明抗磨剂与防腐剂在摩擦副表面存在竞争吸附的关系，并且防腐剂在轴承表面的吸附量决定了航空润滑油的腐蚀效果。

Abstract: A series of lubricating oils containing different mass fractions of anticorrosive and antiwear additives are confected. The corrosion simulating experiments of bearing in those lubricating samples are performed using an axletree balls corrosion simulating assessment equipment，and the laboratory findings are quantitatively processed according to the corrosion grade criterion. The result shows that both the anticorrosive and antiwear additives can affect the anticorrosive property of lubricating oil. The ultra-voilet absorbency of the lubricating oil is measured before and after the addition of antiwear additive, and the mass fraction change of anticorrosive additive in interfacial film is calculated. The calculated result is compared with the anticorrosive property change between the lubricating oils before and after the addition of antiwear additive. It is found that the change in the absorbability of anticorrosive additive in the interfacial film is consistent with the anticorrosive property change of lubricating oil, which indicates that the sorption between antiwear and anticorrosive additive on the surface of axletree is interactive, and the anticorrosion effect of lubricating oil is determined by the quantity of anticorrosion additive adsorbed on the interface of axletree balls.
