对三种工艺条件下磷化处理的试样进行耐盐雾腐蚀试验以区别优劣。根据扫描电镜、电子探针和X光衍射仪等的显微分析 ,揭示了磷化膜耐蚀与否的主要因素 ,为制订优化的磷化工艺提供了依据。
Salt phosphating corrosion test was carried out on the phosphated samples under the three process conditions to distinguish the advantages and disadvantages. According to the microscopic analysis of SEM, XRD and XRD, the main factors of the corrosion resistance of the phosphate coating were revealed, which provided the basis for the formulation of the optimized phosphating process.
