磷化或磷化锌，一种磷酸锌涂层用于低碳钢以获得抗腐蚀反应的保护层。虽然这种方法适用于低碳钢，但由于316 L型不锈钢（316 L SS）的化学反应性较低，因此不可能。为了研究在316 L不锈钢表面制备磷酸锌涂层的可能性，在磷酸锌溶液中对316 L不锈钢进行了不同温度和时间的水热处理。SEM观察和EDX分析表明，在200°C下24小时成功地制备了磷酸锌涂层。XRD分析表明，涂层的晶相为锌尖晶石（ZnFe3+2（PO4）2（OH）2）。附着力测试表明，涂层与316L不锈钢基体的附着力较强（大于12.0±1.4MPa）。
Parkerizing or zinc phosphatizing, a kind of zinc phosphate coating is utilized for mild steel to acquire a protective layer against a corrosion reaction. Although this method is useful for mild steels, it is not possible for 316L-type stainless steels (316L SS) because of their lower chemical reactivity. In order to investigate the possibility of preparing zinc phosphate coating on 316L SS, substrates were subjected to hydrothermal treatment in zinc phosphate solution at different temperatures and duration times. SEM observation with EDX analysis showed that the zinc phosphate coating layer was successfully prepared at 200°C for 24h. Besides, XRD results indicated that the crystal phase of the coating layer was assigned to zinclipscombite (ZnFe3+2(PO4)2(OH)2). Adhesive test indicated that the coating layer was strongly attached on the 316L SS substrate (more than 12.0±1.4MPa).
