摘 要
在本次实验前查阅文献了解磷化工艺各种类型的优缺点，而锌系性能优良是目前研究的主要方向，因此提出锌系磷酸盐处理作为本研究方向。实验确定磷化处理工艺的各种条件，温度为30—500C，PH值为2.8左右，促进剂为亚硝酸钠1.0g/L，添加剂为氟化钠1.0—1.5g/L。再通过正交实验确定中低温磷化配方：氧化锌为8.00g/L，磷酸为0.07mol/L，硝酸为0.06mol/L, ,硝酸镍为1.00g/L。

Abstract
Consults literature understanding phosphorization craft each kind of type before this experiment the good and bad points, but the zinc is the performance is fine is the main direction which at present studies, therefore proposed the zinc is the parkerising takes this research direction. The experiment determined the bonderizing craft each kind of condition, the temperature is 30--500C, the PH value is about 2.8, promoter for nitrous acid coin 0g/L, chemical additive for sodium fluoride 1.0---1.5g/L. Again determines the low temperature phosphorization formula through the orthogonal experiment: The zinc oxide is 8.00g/L, the phosphoric acid is 0.07mol/L, the nitric acid is 0.06mol/L, the nickelous nitrate is the 1.00g/L
