Outline of Final Research Achievements	Nickel and copper are detrimental to recycling processes, due to the difficulty of removal when scrap steel is melted. Therefore, it is important to improve the corrosion and oxidation resistance of steels without the use of these elements. Aluminizing is considered to be an attractive alternative treatment in this respect. A powder eutectic coating using Al and Ti powder on Fe substrate is performed by laser scanning method. It can be confirmed that the coating layer by using Al, Ti and Fe metal powder sheet material shows high oxidation resistance. A double heating process was effective for homogenization of the aluminum concentration over the entire coated layer.
