考察了炭纤维及PTFE增强PEEK复合材料在干摩擦和水润滑下的摩擦学性能,并研究了该复合材料在两种条件下的磨损机理.结果表明,干摩擦下复合材料的摩擦系数和磨损率随负荷的增加不断减小;水润滑下复合材料的摩擦系数随负荷的变化不大,磨损率随负荷的增加而增大.干摩擦下,复合材料的磨损以粘着磨损和磨粒磨损为主.水润滑条件下,磨损表面比较光滑,仅有微切削的痕迹,磨损方式以轻微磨粒磨损为主.干摩擦条件下,摩擦对偶表面仅有轻微的犁沟形成,表面形成一层薄而均匀且结合紧密的转移膜.水润滑下,对偶表面犁沟较深,犁削作用明显,转移膜的形成被明显抑制.水的冷却作用使得向摩擦对偶的粘着转移明显减轻,同时由于摩擦表面吸附水膜的边界润滑作用,显著改善复合材料的摩擦磨损性能. |

The tribological behavior of carbon fiber and polytetrafluoroethylene reinforced; Polyetheretherketone composites were comparatively evaluated under dry and water lubricate*! sliding. The wear mechanisms of PEEK composite were discussed as well. The result indicate that water can reduce the wear rate of PEEK composite. The wear rates of composite show much lower under water lubrication than under dry sliding, owing to the boundary lubrication effect of the water-adsorbed layer and the cooling effect of water. The wear of PEEK composites are characterized by adhesion and abrasive under dry sliding. Contrary to the above, a small amount of exposed and locally polished fibers are observed on the worn composite surface under water lubrication. In this case the micro-scuffing is seen. The thin coherent and compact transfer film on the counterpart stainless steel formed under dry sliding is markedly prevented under water lubrir* tion. |
