Abstract

Corrosion behaviour of coatings sprayed with water-atomized (WA), cast iron powder were investigated by surface analyses and electrochemical methods, such as potentiodynamic polarization test and electrochemical impedance spectroscopy (EIS) in deaerated 0.5 M H₂ SO₄ solution. WA cast iron powders of Fe-3.75C-3.60Si-3.93Al (wt.%) were deposited onto an aluminum alloy (AA383 alloy) substrate by atmospheric DC plasma spraying. Four types of samples were prepared including cast iron liner and aluminum alloy substrate. C₁ coating was produced by using as-received WA cast iron powders without graphite and C₂ coating by using pre-annealing cast iron powder containing graphite structure. The results of the electrochemical tests indicated that the C₂ coating had greater corrosion-resistant properties than the C₁ coating, which could be attributed to its lower porosity, higher protective efficiency, and increased packing factor.
