This work investigates in situ friction-generated copper nanoparticles at the sliding in the precursor solution of copper formate tetrahydrate and octylamine, which induced by frictional heat, it can effectively mitigate wear while slightly reducing friction coefficient. The frictional heat between tribo-pairs accelerated the decomposition of the precursor into in situ generated copper nanoparticles, as indicated by black stripe regions on the worn surface. This study opened a new strategy to achieve low friction and wear through the thermal decomposition of the liquid lubricants during sliding.

钢摩擦副之间滑动界面处的原位摩擦诱导铜纳米粒子及其摩擦学性能

这项工作研究了在摩擦热引起的甲酸铜四水合物和辛胺的前体溶液中滑动时原位产生摩擦的铜纳米颗粒，它可以有效减轻磨损，同时略微降低摩擦系数。摩擦副之间的摩擦热促进了前体分解成原位生成的铜纳米颗粒，如磨损表面上的黑色条纹区域所示。这项研究开启了一种新的策略，以通过在滑动过程中液体润滑剂的热分解来实现低摩擦和磨损。
