The oxidation behavior of hot-dip aluminized AISI 1020 steel was studied at temperatures 700, 750, and 800 °C in air and water-vapor at atmospheric pressure. The high temperature oxidation of the steel has been improved by the hot- dip aluminized steel and the oxidation kinetics accords with a parabolic law. The aluminized steels exhibit a very low oxidation on the kinetics rates at elevated temperatures in air. Whereas, the aluminized steels exposed to water-vapor oxidation show that the alumina layer (Al2O3) formed on the surface coating has less protection than in air atmosphere. The presence of water in the oxidant gasses atmospheres leads to the rapid growth of sporadic iron oxide nodules on the coating surface and the steel substrate. Therefore, the oxidation rate is increased resulting in substantial mass-gain with the temperature and time.
