Summary:A local surface coating using Al and Ti powders on Fe substrate is successfully performed by a laser heating method. A high hardness and high oxidation resistance can be achieved by this method. The thickness of aluminum rich layer can be controlled by the amount of the Al and Ti powder mixture paste. Concentration of aluminum at the coating layer increases with increasing laser scanning speed. Pre-heating at 573K for 10.8 ks improves the uniformity of the coating.
