Abstract

This study investigates the abrasive wear resistance of supersonic electric arc coatings made from cored wires (CW) of the Fe-Cr-Si-Mn-B-C alloying system. Results indicate that increasing the chromium content in the CW charge from 6 to 17 wt.% enhances the wear resistance of the coatings in both subsonic and supersonic spraying modes. Additionally, incorporating up to 2% boron significantly boosts wear resistance. Supersonic spraying increased coating wear resistance by 20-70%. Coatings produced via supersonic spraying showed wear resistance twice that of high-carbon hardened U12 steel (hardness: 840 HV0.3), which is used as a standard for comparison.
