摘要
镁合金基体表面质量对镀覆质量有着至关重要的影响,从而影响到镁合金最终的使用性能,因此创造性的提出砂带磨削作为镀覆前处理的加工方法;在镁合金砂带磨削正交试验基础上,分析了磨削各主要参数对粗糙度的影响规律,建立了基于BP网络的砂带磨削表面粗糙度的预测模型,从而指导工程实践。
Magnesium alloy matrix quality is important impact on the quality of coating on the surface,thus affecting the final performance of magnesium alloy. It creatively put forward a method that using the abrasive belt grinding as a pre-treatment processing method in magnesium alloy. Based on the orthogonal test in the abrasive belt grinding for magnesium alloy,analyze the effect rule on roughness concentration of some main parameters in grinding and build the prediction model of samples surface roughness using abrasive belt grinding based on BP network ,which can guide the engineering application.
