FLUX CORED WIRE Russian patent published in 2018 - IPC B23K35/368 

FIELD: technological processes.

SUBSTANCE: invention can be used in the restoration and hardening of parts operating under conditions of friction and shock loads, in particular, augers, scrapers, blades, plungers. Wire consists of a steel sheath and a powdered mixture containing the components in the following ratio, wt.%: chromium 1.0–11.0, boron carbide 1.5–3.5, ferrochrome 15.0–35.0, titanium diboride 1.5–3.5, zirconium diboride 1.5–3.5, aluminum 0.8–1.2, sodium silicofluoride 0.8–1.0, steel shell – the rest. Composition of charge varies depending on deposition method including coefficients of transition of alloying elements in weld metal.

EFFECT: cored wire has good welding and technological properties and provides high wear resistance of the weld metal.
