Surface alloying caused the improvement in the mechanical/chemical properties of near surface regions of the steels. In the present study, surface alloying treatment with boron, molybdenum, and iron on the AISI 1020 steel was realized by the technique of TIG welding. Ferrous boron, ferrous molybdenum, and Armco iron were used for surface alloying treatment. Before the treatment, ferrous alloys were ground and sieved to be smaller than 45 μm. The powders were mixed to be composed of Fe_{(15-x)}Mo_{x}B_5, where x = 1, 3, and 5 (by at.%). Prepared powders were pressed on the steel substrate and melted by TIG welding for surface alloying. Wear tests of the surface alloyed AISI 1020 steels were realized against WC-Co ball using by ball-on-disk method under the loads of 2.5, 5, and 10 N at the sliding speeds of 0.1 m/s for 250 m sliding distance. Friction coefficient and wear rates of the surface alloyed steel with Fe_{(15-x)}Mo_{x}B_5 alloy powder are changing between 0.30 and 0.80 and 5.86 × 10^{-5} mm^3/m to 2.52 × 10^{-3} mm^3/m depending on applied load and alloy composition, respectively.
