Abstract In this study, a new nitriding process is proposed to produce the aluminum nitride on the aluminum surface. A process of combined barrel and plasma nitriding techniques was used. By using the barrel nitriding process, an aluminum nitride layer with high thickness can be formed within a matter of hours, and the surface hardness can be improved by using the plasma nitriding. It is suggested that a combined technique of the barrel nitriding and the plasma nitriding is one of the most promising surface treatments for the aluminum.
