弹性金属氟塑料轴瓦表面摩擦的定向机理分析

The Analysis of Orientation Mechanism about Friction of Elastic-metallic-plastic Pad

通过对磨损后表面的显微观察与分析 ,发现了弹性金属氟塑料 (EMP)轴瓦与钢对摩时 ,其摩擦副两表面都存在转移或析出 PTFE的高度定向现象 ,结合弹性金属氟塑料表层材料的表面分子结构特性 ,对其定向机理进行了研究。

In the case of steel sliding against elastic metallic plastic (EMP) pad,the orientation process,drawing PTFE chains oriented along the sliding direction,are observed on the surfaces of EMP and steel with electron microscope.Combined with the structure characteristics of PTFE molecular,the orientation mechanism are studied.
