| Abstract: | This paper studies the best formula and optimum conditions of ＂4 in 1＂ phosphate, which has the functions of removing oil and rnst. phosphate, passivating for iron and steel. The results show that the inorganic components of ＂4 in 1＂ phosphate solution formula that impact corrosion resistance of phosphate film are ： Zn （NO3）2, ZnO, KClO3, NaF, H3PO4 ; the best formula of＂4 in 1＂ phosphate solution is： 7.5 g/L C2 H5OH, 310 ml/L H3PO4 , 14g/L ZnO, 26g/L Zn （NOa）2, 6g/L Ni（NO3）2, 0.02-0.04g/L Cu（NO3）3 , 4g/L KClO3 , 8g/L NaF, 5g/L surfactant A, 5g/L surfactant B. SEM analysis showed that the phosphate film has high resistance and low polarization current, and the impedance value can reach 500 kohm; the corrosion resistance of phosphate film has（copper sulfate intravenous drip） good reliability, and can fully meet the iron and steel processing requirements. |
