研制了一种适用于高负荷条件下运行的PEEK背衬型自润滑复合材料,考察了该材料的摩擦学性能及显微结构。结果表明:高负荷条件下,复合材料受到微切削和微犁沟作用,在对偶面产生较厚的转移膜,使材料磨损率下降。
A PEEK-backed self-lubricating composite material was developed for high-load operation. The tribological properties and microstructure of the PEEK-backed composite material were investigated. The results show that under high load conditions, the composite material is subjected to micro-cutting and micro-furrowing, resulting in thicker transfer film on the dual surface and reducing the material wear rate.
