| Abstract: | Steels with four different galvanizing coatings (zinc, zinc–aluminum–magnesium, zinc–iron, and zinc–aluminum) were coated with an acrylic thin organic coating and a solventborne polyurethane topcoat, followed by mechanical and water condensation testing. All the coatings passed the standardized mechanical testing (T-bend and impact resistance) and water condensation testing on flat panels (100% RH, 40°C for 1500 h). However, a combined deformation (T-bend at 0 T) and water condensation test (100% RH, 60°C for 48 h) showed differences between the samples. Below the seemingly intact organic coating, zinc and zinc–aluminum coatings showed thinning during deformation, and good early-stage resistance to humidity-induced metal oxidization. Zinc–aluminum–magnesium coating was more brittle, exposing steel, and initiating the galvanic protection process, which, because of Al and Mg content, was less pronounced than for the zinc–iron coating. Ion beam milling combined with high-resolution SEM-EDS provides an unparalleled technique to assess the early-stage degradation mechanisms and facilitates tailoring of more resistant coating systems.
