counterface

Wear of the polyethylene counterface results in osteolysis and impingement, both of which culminate in aseptic loosening.

聚乙烯界面磨损导致骨溶解和撞击综合症，最终发展为无菌性松动。

The serious plowing, plastic deformation, adhesion and fatigue wear are dominant for PA1010, and the transfer films of PA1010 on the counterface are not homogeneous and have tears in the films.

PA1010的磨损主要表现为严重犁削、粘着、劳和塑性变形，其转移膜不均匀，且有脱落现象。
