Testing and Evaluation of Zinc-Iron and Zinc-Nickel-Tin Coatings on Test Panels

摘要

Testing and evaluation were conducted on two zinc alloy coatings (zinc-iron and zinc-tin-nickel) applied to test panels. Testing included current potential, adhesion, and salt fog testing. The appearance, coating thickness, and metallography of the coatings were also assessed. Each of the coatings was able to withstand over 1000 hr of salt fog testing without the formation of substrate corrosion.
