A phosphate coating as produced from a stock manganese phosphating bath was studied. An addition of manganese citrate, tartrate or gluconate was made. Processing was accomplished in an autoclave at temperatures above 212 degree F with steam pressure to determine the composition of the coating and the reactions associated with their formation.
