COMPOSITE ELECTRODE Russian patent published in 2002 - IPC

FIELD: welding production, namely mechanized systems for electric-arc surfacing, possibly strengthening of flat and cylindrical surfaces of parts operating in condition of metal-to-metal friction with use of abrasive layer such as caterpillar tracks, segments of guiding wheels, runners of excavators and so on. SUBSTANCE: composite electrode includes low-carbon steel base and additive containing aluminium, chrome, nickel at next relation of electrode components, mas.%: aluminium, 12-15; chrome, 0.5-0.9; nickel, 0.3-0.4; low-carbon steel base, the balance. EFFECT: lowered trend to hot cracking, enhanced wear resistance of surfaced metal. 2 cl, 2 tbl
