COMPOSITION OF ELECTRODE COATING FOR WEAR-RESISTANT WELDING DEPOSITION ON PARTS Russian patent published in 1997 - IPC

FIELD: electrode coatings. SUBSTANCE: invention relates to electrode coatings for welding deposition of doped alloy onto surface of parts operating under shock lading and abrasive wear conditions. Coating is made up, wt. -%: marble, 32-48; fluorspar, 10-20; ferrochromium-boron, 12-20; graphite, 1-6; ferrosilicon, 6-12; ferrovanadium, 1-6; rutile, 2-8; metal chromium, 3-5; and nickel, 1-7. Highest efficacy is revealed by composition in which powder mixture of foundry alloy contains ferrochromium-boron and metal chromium in proportion 4:1. EFFECT: increased loss of chromium into oxidation products, excluded use of toxic manganese as deoxidizing agent. 2 cl, 2 tbl
