【Abstract】 A phosphating solution, used for treating the surfaces of ir on and ste el prior to being coated, has been prepared using orthogonal tests. The effects of some factors such as phosphating temperature and time, the pH value and conce ntration of phosphating solution, and the procedure for further treatment, etc. On the quality of the surfaces treated by phosphating were investigated.更多还原
