Abstract

"COMPOSIçãO LìQUIDA HOMOGêNEA, E, PROCESSO PARA MELHORAR A RESISTêNCIA à CORROSãO DE UM OBJETO DE METAL" A resistência à corrosão de um artigo que tem uma superfície com um revestimento inorgânico primário, tal como um revestimento de conversão, sobre um substrato de metal pode ser melhorada por tratamento do revestimento primário com uma composição selante líquida aquosa que compreende cátions de lítio e ânions vanadato. Este tratamento é particularmente vantajoso para revestimento primários formados sobre ligas de alumínio por tratamento dos mesmos com uma composição aquosa que forma revestimento de conversão obtida por reação de cátions de cobalto, íons acetato, hidroxialquil aminas e peróxido em solução aquosa."HOMOGENEOUS NET COMPOSITION, AND, PROCESS TO IMPROVE THE CORROSION RESISTANCE OF A METAL OBJECT" The corrosion resistance of an article that has a surface with a primary inorganic coating, such as a conversion coating, on a metal substrate can be improved by treating the primary coating with an aqueous liquid sealant composition comprising lithium cations and vanadate anions. This treatment is particularly advantageous for primary coatings formed on aluminum alloys by treating them with an aqueous composition that forms a conversion coating obtained by reacting cobalt cations, acetate ions, hydroxyalkyl amines and peroxide in aqueous solution.
