Abstract:

Old coatings and corrosion products were removed from composite metal assemblie consisting of aluminum, magnesium and steel without an appreciable attack on the basic metals. The composite metal assemblies were recoated simultaneously with tin coatings while in a stannous pyrophosphate solution or a stannatepyrophosphate solution. A wash primer was utilized as a coating material for the composite assemblies. Comparative corrosion tests were performed on the above composite metal assemblies. The tin and wash primer coatings on the metal assemblies inhibited corrosion. The recoated metal assemblies did not have the corrosion resistance of assemblies that had been coated prior to the combining of the metals into composite assemblies. Author
