摘要
对奥贝球铁衬套材料和金属氟塑料自润滑衬套材料的摩擦磨损性能进行研究。结果表明,金属氟塑料自润滑材料与45钢配副的摩擦系数远远低于奥贝球铁材料与45钢配副,金属氟塑料自润滑材料的耐磨性能也优于奥贝球铁材料。由于金属氟塑料自润滑材料优良的自润滑性能,与其配对的45钢的磨耗量也远远低于与AD I对磨的45钢。
The wear resistances of ADI bush material and metal-PTFE self-lubricant bush material was comparatively investigated. It was found that the friction coefficient of friction couples consisting of metal-PTFE self-lubricant bush material and 45 steel was obviously lower that of friction couples consisting of ADI austempered ductile iron and 45 steel. And the wear resistance of metal-PTFE self-lubricant bush material was superior to that of ADI austempered ductile iron. The wear resistance of 45 steel coupled with metal-PTFE self- lubricant bush material was also better than that of 45 steel coupled with ADI austempered ductile iron because of the good self-lubricant property of metal-PTFE material .
