Fretting wear becomes one of most concerning issues in the clinical applications of artificial joints. Polyetheretherketone (PEEK) and PEEK-based composites are promising alternative materials for polymer-on-metal joints. In this study. an experimental investigation is conducted to evaluate the fretting wear behavior and the frictional heating behavior of PEEK and three kinds of PEEK-... https://darthomes.shop/product-category/holiday-ornaments/
