Abstract The cyclic oxidation of aluminide coatings on 16Mn s teel under the condition of quenching in water containing 3.5% NaCl has been stu died.The oxidation was carried out at 600℃ and 800℃ in air.The aluminide coati ngs remarkably improve the oxidation resistance of 16Mn steel.Increasing of the oxidation temperature or existing of NaCl in quenching water causes more severe corrosion.After cyclic test,the aluminide coatings happen to crack.However,these cracks just exist in the surface layer of the coatings.
