摘　　要：磷化是应用于钢铁件涂料涂装工序间防锈和增大涂料与钢铁件附着力的有效措施。通过单因素实验和正交实验确定了"四合一"磷化处理液的最佳配方及工艺条件为:磷酸200mL/L,氧化锌35g/L,氟锆酸钾2.0g/L,钼酸钠2.0g/L,植酸25mL/L,硝酸10mL/L,柠檬酸2.0g/L,硝酸镍1.0g/L,OP 10 4mL/L,常温,20min。该工艺用于涂料涂装前的钢铁表面预处理,具有溶液稳定、耐蚀性好、与涂料附着力强等特点。Phosphating is an effective measure used between steel part coating processes for rust protection and improvement of the binding strength between coating and steel part. The optimal formula and process conditions of a ＂4-in-1＂ phosphating solution for steel surface processing are determined through single factor experiment and orthogonal test： H3PO4 200 mL/L, ZnO 35 g/L, K2ZrF6 2.0 g/L, Na2MoO4 2. 0 g/L, C6H18O24P6 25 mL/L,HNO3 10 mL/L, C6H807 2. 0 g/L, Ni（NO3）2 1.0 g/L, OP 10 4 mL/L, room temperature, processing time 20 minutes. The process is used for the pretreatment of steel surface before coating process, featuring stable solution, good corrosion resistance, strong adhesion with coatings, etc.
