【摘要】 针对研磨液特性对铝合金材料固结磨料研磨过程的影响，引入了3种酸性（磷酸、冰乙酸、乳酸）研磨液，对铝合金试样的固结磨料研磨效果进行了实验研究，提取了铝合金试样的材料去除率、表面粗糙度值及微观形貌等。研究结果表明，铝合金试件表面的材料去除主要为磨粒的机械作用，不同酸腐蚀下铝合金试样表面的材料硬度特性不同，致使其研磨效果存在差异，冰乙酸作用下试样表面的材料去除率最大，而乳酸作用下试样表面的质量最高。磷酸与铝合金作用能生成更易去除的化合物，为此研磨液浓度增大后材料的去除率值增加，表面质量变差，冰乙酸与乳酸的效果相反。研究成果可以为固结磨料研磨技术的发展提供理论参考。更多还原

【Abstract】 Aiming at the influence of the lapping slurry properties on grinding effect of the fixed abrasive grinding, the abrasive grinding test was carried out with aluminum alloy material under three types of acidic grinding slurry condition(Phosphoric acid,Glacial acetic acid, Lactic acid). Then, the test data of material removal rate, surface roughness value and surface morphology of aluminum alloy material were obtained. The results indicate that the material removal of sample surface of aluminum alloy is mainly under the mechanical action of abrasive particles. The hardness characteristics of aluminum alloy surface materials is changed due to the corrosion effect of acidic grinding slurry. Thus, the grinding effect is different. In this study, the material removal rate of the aluminum alloy sheet consolidated abrasive is the largest with glacial acetic acid slurry, and the best surface quality is obtained for lactic acid. Moreover, aluminum alloy material can produce compounds of easily removed under phosphoric acid condition. Thus,bigger material removal rate and worse surface quality of test sample are obtained with higher concentrations of phosphoric acid.The opposite situation is occurred for glacial acetic acid and lactic acid condition. This study offers a theoretical reference for the development of consolidated abrasive grinding technology.更多还原
