硫代锑酸锑的合成与应用

叙述了由 SbCI_3与Na_3SbS_4反应、Sb_2O_3浓碱溶液与Na_3SbS_4反应、配离子[SbCl_4]^-与Na_3SbS_4反应、Sb^(3+)离子的多羟基羧酸配合物与Na_3SbS_4反应制成新型抗磨剂硫代锑酸锑(SbSbS_4)的合成方法。研制的SbSbS_4易溶于碱性溶液,具有良好的极压抗磨性,用于脂中可提高脂的负荷承载能力和抗磨能力。

Research on anti-contact fatigue performance of grease containing nano SbSbS_4 particles

Effects of nano SbSbS4particles on contact fatigue life of a steel ball were evaluated on a self-made ball-rod contact fatigue tester. The anti-fatigue mechanisms of SbSbS4 additive were analyzed by means of SEM and EDAX. It was shown that, when the grease contained SbSbS4, contact fatigue life was improved compared with that of base grease. Nanoparticle absorption action, nanoparticle infiltration action, and extreme pressure and anti-friction performance, explained why SbSbS4 increased the contact fatigue life of the steel ball tested.
