IRON-BASED POWDER FOR PLASMA SURFACING OF PARTS OF AGRICULTURAL MACHINED IN COMPRESSED AIR MEDIUM Russian patent published in 2017 - IPC C23C4/06 C22C38/36 

FIELD: metallurgy.

SUBSTANCE: iron-based powder for plasma surfacing of parts of agricultural machines in compressed air medium contains, wt %: carbon 3.3-4.5, chromium 25-28, silicon 1.0-2.0, manganese 1.0-1.5, nickel, 1.5-2.0; tungsten, 0.2-0.4; molybdenum, 0.08-0.015; sulfur, no more than 0.07, phosphorus not more than 0.06, aluminium 0.1-0.15, titanium carbide 0.2-0.25, the rest is iron.

EFFECT: reduced likelihood of quench crack formation, reduced deformations and carrier when hardening thin-wall hardened surfacing parts by applying additional components in the powder composition while providing required wear resistance of parts of agricultural machines.
