摘要

模拟了多个不同粒径cu 纳米粒子升温熔化过程．模拟结果及分析表明，纳米粒子熔点随其直径单调增加，并逐步向大块晶体过渡；纳米颗粒抗磨减摩机理不同于传统的油性剂和极压剂，正是通过改变摩擦方式、表面修复等来减小摩擦磨损．

Abstract

It studies the temperature rise process of Cu nanoparticles．The melting point of Cu nanoparticles is lower than that of bulk，and it decreases with the decreasing size of nanoparticles．The premehing phenomenon was observed in different—size nanoparticles．The mechanism is different from that of traditional antiwear additives．The resuh indicates that the mode of friction is changed or a thin film is formed．
