Abstract

One of the early failures of coating is blister. Here two different coatings were applied on various materials and micro-structures. The formation of the blister, and its micro-structural and material dependencies were evaluated. It is concluded that general organic coating forms more severe blisters than that of the metallic effect coating. General organic coating protects the samples by insulation film while metallic coating protects by acting as galvanic protection. Therefore, the failure modes are also different, namely blister and filiform corrosion. The dependencies on the micro-structures and on material types also follow the insulation film concept and galvanic protection concept.
