- It is now well established that considerable improvement in the mechanical/chemical properties of near surface regions of materials can be achieved by the process of surface alloying. In the present study, surface alloying treatment with molybdenum and boron on the surface of the AISI 1020 steel was realized by the technique of tungsten inert gas welding. Ferrous boron alloy and ferrous molybdenum were used for surface alloying treatment. Before the treatment, ferrous alloys were grinded and sieved to be smaller than 45 μm. Prepared powder was pressed on the steel substrate and melted by tungsten inert gas welding for surface alloying. Coated layers formed on the steel substrate were investigated using optical and scanning electron microscopy, X-ray diffraction analysis and Vickers microhardness testers. It was shown that surface alloyed layer has composite structure including steel matrix and well distributed boride phases. Borides formed in the coated layers have a small precipitated structure and distributed in the grain boundaries as continuous phases. X-ray diffraction analyses show that coated layers include $Fe_2B$, $Fe_{13}Mo_2B_5$, $Mo_2FeB_4$, and iron.
