Abstract

"PROCESSO PARA O PRé-TRATAMENTO QUìMICO, ANTES DE UM REVESTIMENTO ORGâNICO, DE UMA ESTRUTURA METáLICA COMPóSITA"<D>. Em um processo para o pré-tratamento químico antes da pintura de estruturas metálicas compósitas, que contêm porções de alumínio ou liga de alumínio junto com porções de aço, aço galvanizado e/ ou liga de aço galvanizado, em um primeiro estágio a estrutura metálica é tratada com uma solução de fosfatagem de zinco, que forma uma camada de fosfato de zinco cristalina que cobre a superfície sobre aço e sobre aço galvanizado ou liga de aço galvanizado, mas sem formar uma camada de fosfato de zinco sobre as porções de alumínio, e então, em um segundo estágio, a estrutura metálica é colocada em contacto com uma solução de tratamento, que não dissolve excessivamente a camada de fosfato de zinco cristalina sobre aço, aço galvanizado e/ ou liga de aço galvanizado, mas forma uma camada de conversão sobre as porções de alumínio."PROCESS FOR CHEMICAL PRE-TREATMENT, BEFORE AN ORGANIC COATING, A COMPOSITE METALLIC STRUCTURE" <D>. In a process for chemical pretreatment before painting composite metal structures, which contain portions of aluminum or aluminum alloy together with portions of steel, galvanized steel and / or galvanized steel alloy, in a first stage the metal structure is treated with a zinc phosphating solution, which forms a layer of crystalline zinc phosphate that covers the surface on steel and on galvanized steel or galvanized steel alloy, but without forming a layer of zinc phosphate on the aluminum portions, and then, in a second stage, the metallic structure is placed in contact with a treatment solution, which does not excessively dissolve the crystalline zinc phosphate layer on steel, galvanized steel and / or galvanized steel alloy, but forms a conversion layer on the aluminum portions.
