FLUX CORED WIRE Russian patent published in 2019 - IPC B23K35/368 

FIELD: technological processes.

SUBSTANCE: invention can be used during the coatings deposition on parts, working for abrasion under conditions of abrasive flow influence with large contact loads, in particular for the extruders transporting screws restoration and strengthening. Flux-cored wire consists of a steel sheath and a powdery mixture, containing the components in the following ratio, wt. %: nickel 7–9, manganese 5–7, molybdenum 2–4, ferrotitanium 2–4, ferrovanadium 2–4, ferroniobium 2–4, boron carbide 1.0–2.0, boron nitride 1.0–1.5, sodium silicofluoride 0.5–1.0, iron powder 3.7–18.5, steel sheath is the rest being. Composition of charge varies depending on deposition method including the alloying elements transition coefficients into the welded metal.

EFFECT: invention is aimed at increase in the deposited on parts coatings wear resistance.
