研磨抛光表面微孔织构的影响因素分析

Analysis of Influence Factors for Micro-pores Texture Produced by Grinding & Polishing

  • 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10 μm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10 μm以上孔径的分布表面.

     

    Abstract: Surface texture technology is an effective method to improve the tribological properties. A new technology for surface texturing was developed by grinding and polishing method, which was characterized by carrying out molding process and polishing process simultaneously. Attached to the new technology, the influence of grinding time (0~ 120 min), grinding speed (1.45~10.47 m/s) and slurry concentration (1%~15%) on texturing parameters (micro-pores area density, micro-pores size distribution and surface roughness) was studied during the process. The results shows that the area density of micro-pores on the metal surface gradually declined to finally stabilized with the grinding time. When the grinding speed varied from 1.45 m/s to 10.47 m/s, the area density of micro-pores increased from 2.59% to 16.92%. Besides, the sizes of micro-pores as well as the surface roughness grew with the increasing grinding rate. Moreover, it is easy to obtain the micro-pores less than 10 μm as the grinding speed was lower than 2.09 m/s. Area density of micropores increased from 3.76% to 11.70% as the slurry concentration varied from 1% to 15%, and was approximately a linear increase relationship. In addition, it is easy to obtain the micro-pores size of 10 μm or larger on the metal surface if the slurry concentration was higher than 9%.
