【摘要】：表面织构是一种改善摩擦学性能的有效手段.通过研磨抛光方法开发了一种新型表面织构技术,此表面织构的特点是表面微孔成型和抛光过程同步进行.同时利用此织构技术着重研究了研磨时间(0~120 min)、研磨速度(1.45~10.47 m/s)、研磨液质量分数(1%~15%)对织构参数(微孔面积密度、孔径分布及表面粗糙度)的影响规律.结果表明:表面微孔面积密度随着研磨时间增长而逐渐下降并最终趋于稳定;当研磨速度从1.45~10.47 m/s变化时,微孔面积密度从2.59%增至16.92%,微孔孔径及表面粗糙度随着研磨速度的增加而增加,当研磨速度低于2.09 m/s时容易获得10μm以下的微孔;当研磨液质量分数从1%~15%变化时,微孔面积密度从3.76%~11.70%变化,近似呈线性增加关系,质量分数高于9%时易于获得10μm以上孔径的分布表面.
[Abstract]:Surface texture is an effective means to improve tribological properties. A new surface texture technology was developed by grinding and polishing. The feature of surface texture is that the process of surface micropore forming and polishing is synchronized. At the same time, the effects of lapping time (120 min), lapping speed (1.45 ~ 10.47 m / s) and grinding fluid mass fraction (1 / 15) on texture parameters (micropore area density, pore size distribution and surface roughness) were studied. The results show that the surface micropore area density decreases gradually with the increase of grinding time and eventually tends to be stable, and when the grinding speed changes from 1.45 to 10.47 m / s, The micropore area density increased from 2.59% to 16.92%. The micropore diameter and surface roughness increased with the increase of grinding speed. When the grinding speed was less than 2.09 m / s, the micropores below 10 渭 m were easily obtained, and when the mass fraction of grinding fluid changed from 1% to 15%, The micropore area density varies from 3.76% to 11.70%, approximately linearly increasing. When the mass fraction is higher than 9, it is easy to obtain the distributed surface with pore size above 10 渭 m.
