  • The effect of Particle size of coating Powder and coating temperature on the Properties of coating layer was studied by calorizing(or aluminizing). The surface properties of coating layer were fully characterized, using SEM and EDXS. Coating powders were separated according to the particle size by 3 steps and the coating temperature was varied from $950^{\circ}C$ to $980^{\circ}C$. Calorizing with pack cementation method carried under Ar atmosphere for 5 hrs. Results show that the thickness and Al content of coating layer increased as the size of coating powder decreased and coating temperature increased. And pores formed on the coating layer reduced and homogeneity of coating layer increased with smaller particle size of coating powder.

  • 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.
