摘要
摩擦磨损导致能源浪费和零部件失效,纳米自修复添加剂能够降低摩擦磨损,延长机械的使用寿命,还可在不拆卸的情况下对机械零件表面进行在线修复,实现终身免大修,给传统的维修带来了全新的理念。探讨了摩擦磨损自修复的原理,指出摩擦磨损自修复的原理主要有摩擦自修复、原位摩擦自修复和摩擦自适应修复等。概述了几种纳米自修复添加剂的研究应用现状,包括纳米金属粉末、纳米金属氧化物、纳米硫化物、纳米硼系和稀土类化合物及其它新型纳米材料。
Friction and wear leads to the waste of energy, as well as the mechanical disorder. Nanometer self-repair additives bring forward a new concept to traditional repair, such as reducing friction and wear, prolonging machine lives, repairing the tribo-parts surfaces in situ on duty, achieving mechanical fill for life. The friction and wear self-repair principles were discussed, which comprise friction self-repair principle, original friction self-repair principle, friction auto-adjusting repair principle, and so on. Studying status of several nanometer self-repair additives was summarized, including nano-metal powder, nano-metal oxide, nano-metal sulfide, nano-boride, lucium compound and other new nano -materials.
