This paper dealt with an environment protective phosphating with hydroxylamine sulphate as main accelerant. There were no nickel ion, nitrite, benzene and other harmful substances in the phosphated coatings. The structure, component and properties of the coatings were analyzed. The phosphating process and its influence on powder, electrophoresis and heavy anti-erosion coatings were also studied. The results showed that this processing had some virtues, all of the processing was carried out at room temperature; the phosphated coating was fine and the service life of the phosphating solution is longer. And also the phosphated coating had good properties.
