Abstract
A coating method for steel using a mixture of Al and Ti powders has been developed. Pure iron and a carbon steel (JIS-S45C) were successfully coated by the new method, where the coated layer consisted of iron aluminide: Al2TiFe, FeAl, etc. The thickness and chemical compositions of the layer were influenced by heating history and mixing weight ratio of Al and Ti powder. The coated specimen showed neither cracking nor peeling after cyclic heating test between 293 and 973K in air, revealing high oxidation resisitance.
