聚四氟乙烯摩擦学改性研究进展
Progress in tribological modification of PTFE
摘要
Abstract
Polytetrafluoroethylene(PTFE),as a special engineering plastic,has many advantages such as excellent self-lubricating properties,good chemical stability,and a wide range of operating temperatures.However,its core disadvantages are poor wear resistance and easy wear,which seriously shorten its service life.Starting from the structural characteristics of PTFE molecules,this article takes the transfer film theory as the main thread to deeply analyze the friction and wear mechanism of PTFE and the research and development process.It summarizes the tribological modification methods of PTFE,analyzes the common methods of surface modification,filling modification,and blending modification,compares the internal mechanisms of these three types of modification methods,and summarizes the development trend of composite modification.Finally,based on recent research achievements and existing problems in the research process,the research direction of PTFE tribological modification is discussed,some suggestions on the quantitative study of transfer film,the industrial feasibility of multimode type collaborative composite modification,the selection and application of modification system under actual working conditions are given.关键词
