摘　　要：分析了化学镀Ni-P合金沉积机理中最为重要的原子氢理论,简述了磁流变抛光过程中材料去除机理,并选取在磁流变抛光过程中主要的工艺参数进行正交实验。利用Zygo干涉仪等实验仪器检测实验件面形,计算出每个去除函数的峰值去除率。通过实验数据分析各因素对Ni-P合金镀层抛光效率的影响规律。实验结果表明各因素对Ni-P镀层抛光效率的影响关系:抛光粉浓度>抛光间隙>抛光轮转速>镀层厚度,通过实验并结合工程实际情况对各工艺参数进行了优化,为后续Ni-P合金镀层非球面表面抛光打下基础。The most important atomic hydrogen theory in the deposition mechanism of electroless Ni-P alloy was analyzed.The material removal mechanism in magnetorheological finishing process was studied.The main process parameters in the magnetorheological finishing process were selected for orthogonal experiment.Using Zygo interferometer and other experimental instruments to detect the surface of the experimental part,the peak removal rate of each removal function was calculated.The influence of various factors on polishing efficiency of Ni-P alloy coatings was analyzed by experimental data.Experimental results show that the influence of various factors on the polishing efficiency of Ni-P coating:polishing powder concentration>polishing gap>polishing wheel speed>coating thickness.Through experiments and combining with the actual engineering situation,the process parameters were optimized to lay a foundation for the subsequent aspheric surface polishing of Ni-P alloy coating.
