摘　　要：三乙醇胺硼酸酯是一种新的绿色水基全合成切削液防锈添加剂,但其在切削加工过程中的摩擦学特性尚未有报道。以钛合金与硬质合金为摩擦副,通过摩擦磨损试验比较三乙醇胺硼酸酯并与传统润滑添加剂丙三醇和聚乙二醇的摩擦学性能,同时考察不同含量的三乙醇胺硼酸酯水溶液的摩擦学性能。结果表明:三乙醇胺硼酸酯具有与丙三醇和聚乙二醇相似的减摩抗磨性能,在相对较高的载荷下,三乙醇胺硼酸酯的润滑性能更优;三乙醇胺硼酸酯水溶液的减摩抗磨性能随着其含量的增加逐渐增强,当三乙醇胺硼酸酯的体积分数达到40%以上时,溶液的润滑性能更为显著。研究表明,三乙醇胺硼酸酯有可能成为一种新型切削液润滑添加剂。Triethanolamine borate is a new anti-rust additive of green water-based synthetic cutting fluid,but its tribological properties in cutting fluid have not yet been reported.The tribological properties of triethanolamine borate as lubricant additive for cutting fluid were studied by using titanium alloy and cemented carbide as friction pairs,and were compared with those of the traditional lubricating additives of glycerol and polyethylene glycol.The tribological properties of triethanolamine borate solution with different content were also investigated.The results show that triethanolamine borate has the same friction reducing and anti-wear properties as glycerol and polyethylene glycol.Under relatively high load,the lubrication performance of triethanolamine borate is better than that of glycerol and polyethylene glycol.The friction reducing and anti-wear properties of triethanolamine borate is increased with the increase of its content in aqueous solution,when the volume fraction of triethanolamine borate reaches more than 40%,the lubrication performance of the solution is more significant.The results show that triethanolamine borate may be a new lubricating additive for cutting fluid.
