In this study, Fe(13-x)VxB7 (x = 0, 1, 2, 3 and 5) based hard surface alloy layers were formed on SAE 1020 steel substrate surface by tungsten inert gas (TIG) welding method. The effects of vanadium addition on microstructure, hardness and wear rate in this coating layer were investigated using optical microscope, SEM (EDS), X-ray diffractometer, hardness and wear tests. As a result of microstructure studies and phase analysis, it was determined that the structures of alloy layers consist of alpha-(Fe,V), alpha-(Fe,V) + (Fe,V)(2)B eutectic, and (V,Fe)B phases. As a result of the macrohardness tests, it was found that the hardness of the alloy layers varied between 42.3 +/- 1.7-57.2 +/- 5.1 HRC. Moreover, the microhardness of iron and vanadium borides formed in the coating layers was found to be between 1901 +/- 127-3082 +/- 299 HV0.01, respectively. As a result of the wear tests, it was observed that as the amount of vanadium added to the hard surface alloy layer increased, the wear rates decreased for all applied loads. Morover, Scanning Electron Microscopy (SEM) images of the worn surfaces showed that the wear mechanisms were adhesive, micro-abrasive and oxidative.
