The purpose of this study is to improve the hardness and wear resistance characteristics of the aluminum alloy using Plasma Transferred Arc process, called PTA process. The PTA process has been mainly applied to surface modification to steel products. It has some difficulties to apply this PTA process into aluminum products due to its low melting point and high thermal conductivity. It can be possible to make stable surface modification to aluminum alloy optimizing plasma current and powder supply. Niobium carbide powder was selected to obtain the optimum hardness and wear resistance during a series of experiments using PTA process. As the conclusions, sufficient hardness and wear resistances were archived at the surface modified layer by controlling niobium carbide composition to aluminum powder in the PTA deposit metal. Deposits which have no blowhole, crack and detachment from base metal were obtained in case of more than 60%NbC content of mixture ratio.
