摘要： 针对高质量复杂曲面抛光效率低下的难题，提出了力流变抛光技术，通过调控非牛顿流体抛光液在剪切应力作用下的非线性流变特性以及抛光液流场参数，调节抛光液与被抛光表面间的剪切应力，在被抛光表面形成柔性把持磨粒的流变层实现材料去除。实验研究了力流变抛光技术的工艺特点，结果表明抛光速度、磨料浓度越高，材料去除率越高，抛光表面粗糙度也越小，但抛光液质量分数一定时，抛光表面质量受磨料粒度的影响较弱，且材料去除率随磨粒粒径增大而减小。对石英半球谐振子、硬质合金螺纹梳刀、钽酸锂基片力流变抛光的结果表明，在不需外加辅助物理场条件下，能够实现金属、玻璃、硬质合金、晶体等材料的平面、回转面及复杂曲面的高效超精密抛光，其具有广阔的应用前景。

Abstract: To solve the problems of low polishing efficiency of high quality complex surface, a force rheological polishing(SRP) technique is proposed.By controlling the nonlinear rheological properties of non-Newtonian fluid under shear stress and flow field parameters of the polishing fluid, the shear stress between the polishing fluid and the polished surface is adjusted to form a rheological layer on the polished surface, which flexible gripping abrasive to achieve material removal.The process characteristics of SRP are studied, the experimental results show that the higher the polishing speed and abrasive concentration, the higher the material removal rate and the smaller the polished surface roughness.However, when the polishing fluid mass fraction is constant, the polishing surface quality is less affected by abrasive particle size, and the material removal rate decreases with the increase of abrasive particle size.The SRP results of quartz hemispheric resonator, cemented carbide insert and lithium tantalite substrate show that this method can achieve high efficiency ultra-precision polishing of metal, glass, carbide, crystal and other materials with plane, rotary surface and complex surface without additional physical field, which shows that it has broad application prospects.
