摘要: 塑性加工一般采用润滑油或固体润滑膜对工件进行润滑处理,干摩擦定律作为理解润滑条件下的摩擦行为的基础,可通过类金刚石镀膜镀层模具与板材进行侧拉摩擦试验和高面压摩擦试验来确定。对固体润滑膜下的摩擦定律进行了研究,最后基于干摩擦定律与侧拉摩擦试验,提出了油润滑条件下的摩擦定律。

Abstract: In metal forming, liquid lubricants and lubrication coatings were generally employed. Based on the understanding of friction behaviors under lubricated conditions, the friction law under dry conditions was determined by experimental results in the side stretching friction tests and the high pressure friction tests with a diamond-like carbon(DLC) coated friction tool. Then the friction law of lubrication coatings was investigated. Finally, the friction law under lubricated conditions was proposed based on the friction law under dry conditions and experimental results obtained by the side stretching friction tests.

Key words: metal forming, friction law, dry friction, lubricant
