초록/요약
This investigation has been carried out in order to show heat treatments and cold rolling of steel sheets influence the phosphate coating and to make clear the relationship between the microstructure of the steel and the phosphate nucleation. The activity of phosphate reaction is determined by the number of phosphate nuclet initially formed on the steel surface when commercial phosphate solutions are sprayed. It is found that the activity of phosphate reaction is considerably affected by heat treatments and cold rolling of steel sheet; the phosphate nuclei increase with an increase of cold reduction and a raise of annealing temperature, decrease with an increase of the heating rate and a raise of the quenching temperature
