Abstract A series of nano-oils containing nano-particles (NPs) of talc (≈50 nm size) in varying amounts (0.5, 1, 2, 3 and 4 wt%) and dispersant (1%) was developed. Apart from physical properties, they were evaluated for anti-wear (AW) and extreme-pressure (EP) performance on a 4 ball tester since tribo-potential of nano-talc particles are not explored in the literature. The optimum amount for the best performance was around 2–3 wt % and the enhancements in AW and EP performance were 42% and 122%; highest as AWA ever reported for inorganic NPs in the literature. It was due to remarkable softness and film transferring capability of Talc NPs as physical as well as chemical film.

纳米滑石颗粒增强油品抗磨和极压性能的潜力探索

摘要 开发了一系列含有不同量（0.5、1、2、3 和 4 wt%）滑石（≈50 nm 大小）纳米颗粒 (NPs) 和分散剂 (1%) 的纳米油。除了物理性能外，由于文献中没有探讨纳米滑石颗粒的摩擦电势，因此在 4 球测试仪上评估了它们的抗磨损 (AW) 和极压 (EP) 性能。最佳性能的最佳用量约为 2-3 wt%，AW 和 EP 性能的提高分别为 42% 和 122%；文献中无机 NP 的 AWA 报告最高。这是由于滑石纳米颗粒的显着柔软度和薄膜转移能力以及物理和化学薄膜。
