ELECTRODE COATING COMPOSITION FOR PREPARING WEAR-RESISTANT ALLOY OPERATED IN ABRASIVE ENVIRONMENT 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 operated under conditions of abrasive wearing with shocks characterizing by different dynamics. Coating composition contains, wt.-%: marble, 10-18; fluorspar, 8-16; rutile, 3-10; and nickel, 1-5. Composition strengthening agent constitutes granules consisting of chromium and titanium diborides at ratio 3:2 with nickel, manganese, and aluminum additives. Complex deoxidizing agent consists of mixture of graphite, manganese, ferrosilicon, and ferrotitanium powders taken in equal amounts. Proportion of all components in electrode coating allows forming strengthening phase in deposited metal consisting of original titanium and chromium diborides non-melted during welding deposition process and chromium carboborides Cr₂₃(CB)₆ and titanium carbide contained in melt. EFFECT: increased strength of welding deposit. 3 cl, 2 tbl
