Abstract
Wear resistance was studied at wearing by fixed and unfixed abrasive of metal deposited with PP-AN192 flux-cored wire (strengthened by titanium carbides) and by Hardface HC-O flux-cored wire (strengthened by chromium carbides). It is found that both the deposited metal types, despite the different total content of alloying elements (30 % for Hardface HC-O and 10 % for PP-AN192), have approximately the same wear resistance. Structure of deposited metal of both the types consists of martensite, small quantity of residual austenite and carbides of different composition. Here, the high wear resistance of metal deposited with PP-AN192 flux-cored wire is attributable to the fact that titanium carbide contained in it is greatly superior in terms of hardness and wear resistance to chromium carbides, hardening the metal deposited with Hardface HC-O flux-cored wire. 10 Ref., 4 Tables, 6 Figures.
