摘　　要：结合天然蛇纹石矿物粉体材料在工业减摩和在线磨损修复领域的实践应用,基于Block闪温理论和Lewis酸碱理论提出来“闪温熔覆”理论模型,并依据天然层状硅酸盐的摩擦学特性,提出了“金属表面自生强化技术”的工程概念。在复合功能粉体材料介入的前提下,借助摩擦能,复合功能粉体材料会与运动副摩擦表界面发生一系列的物化反应,完成运动副摩擦表界面改性强化、动态抛光、自适应增材修复、固液多元润滑,构建了设备极低摩擦率、极少磨损的自润滑环境。该技术可有效提高设备效率,延长关键部件寿命,降低设备故障率和全寿命周期的运维成本,实现节能减排和降本增效。Combined with the practical application of natural serpentine mineral powder materials in the field of industrial friction reduction and online wear repair,the"flash temperature cladding"theoretical model was proposed based on the Block flash temperature theory and Lewis acid-base theory,and the engineering concept of"metal surface self-generated strengthening technology"was proposed based on the tribological properties of natural layered silicates.Under the premise of the intervention of composite functional powder materials,with the help of friction energy,the composite functional powder materials will undergo a series of physical and chemical reactions with the friction surface interface of the moving pair,complete the modification and strengthening of the friction surface interface of the moving pair,dynamic polishing,adaptive additive repair,solid-liquid multi-lubrication,and build a self-lubricating environment with extremely low friction rate and extremely little wear for the equipment,This technology can effectively improve equipment efficiency,extend the life of key components,reduce equipment failure rate and operation and maintenance costs throughout the life cycle,and achieve energy conservation,emission reduction,cost reduction and efficiency improvement.
