<p>This study examined coating process of the surface of medium carbon AISI 1050 steel with Ni-based and B4C-reinforced powders by the arc melting method coating method. This study was aimed to coat the surface of AISI 1050 steel by arc welding, which has a wide usage area, and improves its surface properties. The powders prepared based on the determined parameters were placed in the channels opened on the surface of AISI 1050 steel, and the surface was alloyed by the arc melting method process. Scanning electron microscopy (SEM), optical microscope (OM), X-ray spectroscopy (EDS), and X-ray diffraction (XRD) analyses were done for microstructure examinations between the coating and the substrate material to observe the effect of the coating. Wear and microhardness tests were run to examine the mechanical effect of the coating. The results showed that the coated layer improved the surface of AISI 1050. While microstructural analysis showed no defects, intermetallic compounds were observed in the transition zone. The hardness value exceeded the base material value by 70%, and the specimen reinforced with 3% B4C provided the highest wear resistance compared to the base material.</p>
