摘 要: 采用Sb納米顆粒作為潤滑油添加劑，研究其在不同摩擦條件下的摩擦學(xué)性能和抗磨減摩機理。采用CFT-1型材料性能測試儀進行往復(fù)摩擦試驗，并采用SEM和EDS分析潤滑油的潤滑效果。結(jié)果表明：Sb納米顆粒的添加可以有效地改善潤滑油的抗磨減摩性能；在0.50%(質(zhì)量分數(shù))的添加量下表現(xiàn)出優(yōu)異的抗磨減摩效果；Sb納米顆粒不僅可以吸附在摩擦副表面保護基體材料，還可以對磨損表面進行動態(tài)自修復(fù)。

Abstract:The tribological properties and the anti-wear and reducing friction mechanism of antimony nanoparticles, which were used as lubricating oil additive, were studied under different friction conditions. The reciprocating friction test was done by the CFT-1 material properties tester, and the lubrication effects of lubricating oil were analyzed by SEM and EDS. The results show that the lubricating oil with Sb nanoparticles addition can effectively improve the anti-wear property of lubricating oil. The lubricating oil containing 0.50% (mass fraction) Sb nanoparticles addition exhibits optimal anti-wear property. Sb nanoparticles can not only be absorbed on the surface of friction pair to protect the substrate material, but also have self-repairing function on the worn surface.
