摘　　要：合成一种新型含氮硼酸酯铝材轧制润滑油添加剂,利用四球试验机考察添加含氮硼酸酯的铝材轧制润滑油的油膜强度、摩擦因数,通过显微镜观察磨斑形貌并测量磨斑直径。利用正交试验法评估极压剂含量、基础油种类、四球试验机载荷和转速对含氮硼酸酯润滑油摩擦学性能的影响,并通过多目标优化设计,对4种参数对铝材轧制润滑油摩擦学性能的强化效果进行综合研究。结果表明:各工艺参数对油样的摩擦学性能影响显著性由大到小依次为极压剂添加量、基础油种类、转速和载荷;经过多目标优化设计,得到的含氮硼酸酯铝材轧制润滑油强化工艺参数的最佳组合:极压剂质量分数为1.0%,基础油种类为D100,载荷为294 N,转速为1 200 r/min;通过极差、方差等分析,发现极压剂添加量和基础油种类对油样的摩擦学性能有显著影响。A new type of lubricating oil additive of nitrogen containing borate ester for aluminium rolling was synthe sized.The film strength and friction coefficient of the aluminium rolling lubricating oil with nitrogen containing borate ester were investigated by a four ball tester.The wear scar morphology was observed through microscope and wear scar diameters was measured.The influences of the type of base oil,the content of extreme pressure additive,the load and rotational speed on the tribological performances of aluminium rolling lubricating oils of nitrogen containing borate ester were evaluated comprehensively by orthogonal test.The enhancing effects of four parameters on the tribological performances of aluminium rolling lubricating oils were studied synthetically based upon multi objective optimal design.The results show that the con tent of extreme pressure additive has the greatest effect on the tribological performance of aluminium rolling lubricating oils,followed by the type of base oil,the rotational speed,and the load.Based on the multi objective optimal design,the best parameter combination for the tribological performances of nitrogen containing borate ester aluminium rolling oil was obtained,which is that the content of extreme pressure additive is 1.0%,the type of base oil is D100,the rotational speed is 1 200 r/min and the load is 294 N.The result of the range analysis and variance analysis shows that content of extreme pressure additive and the type of base oil have a significant effect on the tribological performances.
