STRUCTURE AND WEAR RESISTANCE OF CHROME-MANGANESE DEPOSITED METAL

V.L. MALINOV and L.S. MALINOV

Abstract
Presented are the results of investigations into structure and wear resistance of low-carbon metal of different structural classes, deposited with flux-cored strips and containing approximately 13 % chromium and different amounts of manganese (from 2 to 12 %). The possibility of increasing wear resistance of the deposited metal by tempering and case hardening after hardfacing was studied. It is shown that achieving the optimal amount of meta-stable austenite, along with martensite, in structure of the deposited metal improves its wear resistance.
