中文摘要	A water-soluble boron (B)-containing thi- ophosphite derivative (BTP) was synthesized, and its tribo- logical, anticorrosion, and antirust properties as an additive for the base liquid of water–glycol hydraulic ﬂuid were evaluated in detail. The results of tests demonstrated that BTP is indeed a high-performance and multifunctional water-soluble lubricant additive that was able to remarkably improve the extreme pressure, friction-reducing, antiwear, anticorrosion, and rust-inhibiting properties of the base liquid when added at a low adding concentration (\3 wt%). Based on a performance comparison of BTP and thiophos- phite (TP), whose chemical structure is similar to that of BTP but without B, a number of primary conclusions were drawn. The B element existing as alkanolamine borate group could greatly improve the extreme pressure, antiwear, and antirust performance of BTP, especially the antirust performance, but had only a small effect on the friction- reducing and anticorrosion properties. Based on character- izations and analyses of the worn surfaces, we propose that the antiwear mechanism consists of the prepared compound BTP reacting with the steel surface during the friction pro- cess to generate a protective ﬁlm mainly composed of phosphate, sulﬁde, sulfate, organic amine, and B2O3.
