- 摘要:
- 为研究不同密度的微凹波纹表面织构的摩擦特性,首先利用激光表面织构技术,对轴承钢试样表面进行微凹波纹织构化处理; 其次采用销-盘摩擦副接触方式,在常温、常压及液体润滑的条件下,对不同密度的微凹波纹表面织构进行摩擦试验; 最后借助扫描电子显微镜观察其表面形貌,并利用Stribeck曲线分析在不同实验条件下不同密度的微凹波纹织构表面的摩擦特性.结果表明:在一定转速范围内,微凹波纹表面织构的减摩效果随压力的增加而提高,摩擦系数值随着微凹波纹密度的增加而降低,其中密度为22.37%的微凹波纹织构的减摩效果最好.
- Abstract:
- In order to study the friction characteristics of micro-wave surface texture with different densities, the experiment was conducted as following. At first, the micro-wave surface texture on bearing steel were manufactured by the laser texture technology. Then, by using pin-on-disk type friction pairs, the friction experiments of micro-wave surface texture with different densities are carried out under the conditions of normal temperature, atmosphere pressure and fluid lubrication. Finally, by using SEM to observe the surface morphology and the Stribeck curves in different experiment conditions, the friction properties of micro-wave surface texture with different densities are analyzed. The results indicate that in a certain speed range, the reducing friction of micro-wave surface texture increases along with the increasing pressure, the friction value of micro-wave surface decreases with the increasing density and the 22.37% micro-wave shows the best reducing friction effect.
