Abstract
The following study presents the results of wear-resistant layer made of Ni-Cr-Si-B-Fe-C+WC alloy in the form of metallic powder on the AISI 4715 steel. Hardness and abrasion resistance tests were performed in accordance to PN-EN ISO 6508-1:2016 and ASTM G65-00 standards. Obtained data were compared to the abrasion resistant steel produced by Swedish manufacturer. Microscopic observations were made to determine the structure of obtained layer and base material using Olympus SZX9 stereoscopic light microscope. In order to determine the chemical composition of microregions, X-ray microanalysis researches were carried out.
