[origin: US5312492A] PCT No. PCT/EP90/00592 Sec. 371 Date Dec. 10, 1991 Sec. 102(e) Date Dec. 10, 1991 PCT Filed Apr. 14, 1990 PCT Pub. No. WO90/12901 PCT Pub. Date Nov. 1, 1990.The invention concerns a process, not using chlorate or nitrite, for the production of nickel and manganese containing zinc phosphate films on steel, zinc, and/or zinc alloys by spraying, spray-dipping, and/or dipping, using an aqueous solution. An organic oxidizing agent is added, primarily to depolarize the nascent hydrogen produced.
Abstract (fr)
Il s'agit de produire ces couches sur de l'acier, du zinc et/ou d'autres alliages par pulvérisation, par pulvérisation-immersion et/ou par immersion avec une solution aqueuse. L'agent d'oxydation organique ajouté sert surtout à dépolariser l'hydrogène naissant.
