摘要

通过模压烧结法

在碳/ 碳复合材料表面制备了以SiC 为过渡层的聚四氟乙烯( PTFE) 自润 滑复合涂层

同时对复合涂层的摩擦磨损性能进行了测试. 研究结果表明:所制自润滑复合涂层的 摩擦系数为01155

微大于纯PTFE 涂层的摩擦系数(01105～0116)

小于碳/ 碳复合材料的摩擦系 数(01 18～0123)

且其摩擦性能更稳定

磨损量约为纯PTFE 涂层磨损量的1/ 50

磨损机制为黏着 磨损和磨粒磨损.

Abstract

A self2lubricating polytet rafluoroet hylene ( PTFE) composite coating on t he C/ C com2 posites with SiC interlayer was prepared by compression molding and sintering

and t he f riction and wear properties of t he coating were measured. The result s show t hat the f riction coefficient of this compo site coating reaches to 01155

which is higher t han t hat of t he p ure PTFE coating (01105-0116) and lower t han C/ C composites (0118-0123)

and t he f riction property of t he composite coating is more stable t han t hat of t he p ure PTFE coating. In addition

the wear of t he composite coating is about 2 percent of that of p ure PTFE coating. Both abrasion and adhesion serve as t he wear forms of the composite coating.
