The effect of particle size of coating powder and coating temperature on the thickness of coating layer formed on metal surface was studied by using XRD, SEM and EDXS. Coating powder was separated according to particle size by 3 steps and coating temperatures were varied from $950^{\circ}C$ to $980^{\circ}C$. Calorizing carried out at air and Ar conditions for 5 hrs, respectively. XRD result show that $Al_2O_3$ and AlN were formed during calorizing at air condition. The thickness and Al content of coating layer increased as the particle size of coating powder decreased and coating temperature increased.
