摘要
随着纳米技术的发展,纳米表面工程技术已成为再制造工程中的关键技术之一。该文分析了纳米单质粉体润滑材料、纳米稀土化合物粉体润滑材料以及微/纳米矿物粉体润滑材料等的摩擦学性能,得出不同种类的润滑材料具有各自的摩擦学特性。又根据不同种类的微/纳米粉体润滑材料的摩擦学特性,概述了微/纳米粉体润滑材料在润滑油中的抗磨减摩机理、光滑或超光滑表面滚动摩擦作用机理、沉积膜机理与嵌入渗透层/摩擦化学反应膜机理。
With the development of the nano-technology, nano-surface engineering technology has been one of the key technologies of remanufacturing engineering. The tribological behaviors of nano-simple substance lubricant material, nano rare-earth compound lubricant material and micro/nano-mineral powder lubricant material are analyzed in the present article. The conclusion that each lubrication material has its own tribological behavior self is found. According different kinds micron/nano-powder lubricant materials＇ tribological behaviors, the mechanisms of antiwear and antifriction of the micron/nano-powder lubrication materials are summarized, which are the smooth or super smooth surface roll mechanism and the sediment film mechanism as well as the embedding and infiltrating tribochemistry reaction film mechanism.
