| Abstract: |
Thermally sprayed aluminum zinc alloy coating is often utilized to enhance the corrosion resistance performance of aluminum magnesium alloy substrate or carbon steel structures for its sacrificial anode property in the aqueous environment contains sodium chloride. Corrosion behavior of aluminum zinc sprayed coatings in synthetic seawater was investigated. Electrochemical experiments were performed employing the electrochemical impedance method. The corrosion resistance: Rc of aluminum zinc sprayed coating in the static and dynamic contact conditions with seawater were determined. The corrosion resistance performance of flame sprayed aluminum alloy coatings contain 2-6 mass% zinc were quantified.
