Mild steel have good properties that made it a candidate materials for most engineering applications. But in some applications like gears, cam the hardness values at the surface is not adequate that made it have low wear resistance. In order to increases the wear behavior of this novel materials that lead to the investigation of laser alloying of mild steel with Zn-Al-Sn. The laser power of 750 W, scanning speed of 0.6 and 0.8 m/min, alloy composition of 25 % Zn-50 % Al-25 % Sn and 30 % Zn-40 % Al-20 % Sn were used in the research. Standard tribometer was used for the wear evaluation. The results showed that hardness values and wear behavior improved by increasing the Al content from 40 to 50 %. The optimum condition was obtained at 25 % Zn-50 % Al-25 % Sn at laser power of 750 W and speed of 0.8 m/min. It have been established that laser alloying of mild steel with of Zn-Al-Sn is promising for improving the surface hardness values and wear resistance of mild steel.
