Abstract : Aluminum, steel and magnesium trimetal assemblies were simultaneously coated in order to decrease galvanic corrosion, and to develop coatings to be used for recoating structurally united components containing dissimilar metals. The composite specimens were processed in modified stannous pyrophosphate solutions. The trimetal assemblies containing various alloys of aluminum were also processed in the stannous pyrophosphate solution. Composite specimens containing a large aluminum panel and a small magnesium panel, or the reverse, were processed in the stannous pyrophosphate solution. Solutions containing other tin compounds were investigated as solutions to coat trimetal assemblies.
