| Abstract: | Mid-temperature zinc phosphating solution is developed.The formulation of phosphating solution is defined.The phosphating film is valuated with methods of dribble bluestone and weightloss.The influence factors such as total acidity,free acidity,temperature,time are studied and discussed.The effect of phosphating time on the corrosion resistance of the film and the relation between phosphating time and film weight are discussed.The phosphating film is uniform in crystal structure,compact and dark gray.The medium temperature zinc phosphating solution has many advantages: easy to operate,no need to adjust steel surface and save time,so is suitable for mass phosphating of steel tube parts in production. |
