摘要
制备一种水基全合成切削液,考察新型有机钼、有机硼极压剂与三乙醇胺硼酸酯防锈剂的协同作用。利用四球摩擦磨损试验机研究切削液的摩擦学性能;采用一级灰口铸铁进行单片、叠片防锈试验,考察全合成切削液的防锈性能;用激光共聚焦显微镜观察试件表面形貌并测量工件的表面粗糙度,研究极压剂对工件表面质量的影响。结果表明:2种极压剂有协同增效的作用,使用复合极压剂后,极压润滑系数(最大无卡咬载荷与摩擦因数的比值)增大,改善加工工件的表面质量;有机硼极压剂和三乙醇胺硼酸酯防锈剂共同作用可增强切削液的防锈作用;当切削液中添加复合极压剂与防锈剂时,与含有单一添加剂的切削液相比,其极压性能与防锈性能均有提高,表明防锈剂和极压剂在切削液中具有协同作用。
A synthetic cutting fluid was prepared and the synergistic effect between organic molybdenum and organobo- ron extreme pressure agents and triethanolamine borate anti-rust agent was studied.The tribological properties of synthetic cutting fluid were studied with four-ball friction and wear tester; the anti-rust performance was studied through the sheet rust test and laminated rust test with grey cast iron;the surface morphology of the specimen was observed with a laser con- tbcal microscope, and the surface roughness of the specimen was measured to investigate the influence of extreme pressure agent on the surface quality of the specimen.The results show that two kinds of extreme pressure agents have a synergistic effect, which can increase the extreme pressure lubricating factor（ The ratio of the maximum non-seizure load to the friction coefficient） of synthetic cutting fluid,and improve the surface quality of the specimen.The synergistic effect between organoboron extreme pressure agent and triethanolamine borate anti-rust agent can enhance the anti-rust effect of the cutting fluid.When adding compound extreme pressure agents and anti-rust agent in the synthetic cutting fluid, both the extreme pressure performance and the anti-rust performance are increased compared with a single additive of cutting fluid, indicatingthe compound extreme pressure agents have a synergistic effect with anti-rust agent.
