Abstract
A method for forming an adherent phosphate coating on metal articles, comprising contacting said articles with an aqueous phosphating solution having a total acidity within the range of about 5 to 850 dots, and consisting essentially of about 0, 10% to about 40% of the phosphate ion, from about 0.20% to about 55% nitrate ion, and about 0.20% to about 30% of the lead ion, at a temperature of at least about 10º C.
