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, ferrotungsten - 10.0-13.75, ferromanganese - 0.76-1.41, ferrosilicum - 0.26-1.34, ferrochromium - 3.38-5.38, ferrovanadium - 0.4-1.0, nickel - 0.1-1.0, carbon-fluoride-bearing powder of electric precipitator of aluminium production - 0.80-2.58, iron powder making the rest.

EFFECT: higher wear resistance and hardness, stable arc, improved formation of built-up metal.
