POWDER WIRE Russian patent published in 2014 - IPC B23K35/368 

FIELD: metallurgy.

SUBSTANCE: invention relates to surfacing by submerged arc for recovery of worn-out parts and production of protective coating at equipment operated at compression and abrasion loads at 600°C. Proposed composition contains the following substances, in wt %: steel shell - 67.0-68.0, ferromanganese - 0.50-1.2, ferrosilicium - 1.0-1.75, ferrochromium - 7.2-9.1, ferromolybdenum - 1.5-2.3, ferrovanadium - 0.6-0.8, carbon-fluoride-bearing powder of electric precipitator of aluminium production - 0.70-1.20, iron powder making the rest.

EFFECT: higher wear resistance and hardness, ruled out cold cracking decreased hydrogen content in built-up metal, extra gas protection.
