Abstract
Phosphate coating of metals, partic. Zn, Fe and Al and their alloys, using phosphates in aq. acid filmogenic solns. which contain oxidants as acclerators, is by contacting the metal surface with a soln. of phosphate ions, cations forming a coating, and peroxide accelerators, which soln. is practically free of constituents forming water-sol. salts during neutralisation by Ca(OH)2.
