POWDER WIRE FOR WEAR RESISTANT SURFACING Russian patent published in 2005 - IPC

FIELD: restoration of worn parts of low carbon and low alloy steels operating in condition of abrasive wear and impact loads, applying of wear resistant coating.

SUBSTANCE: power wire includes steel envelope and powder like charge having components taken at next relation, mass %: ferrotitanium, 1 - 3; metallic chrome, 6 - 7; ferrosilicon, 0.3 - 0.5; ferromanganese, 1.5 - 2.5; graphite, 0.3 - 0.5; molybdenum, 0.8 - 1.5; fluorspar, 2.0 - 4.5; fieldspar, 0.3 -1.5; hematite, 0.3 - 1.0; steel envelope, the balance. Such wire allows to surface thin and small-size parts in shops, in field and installation condition at lower and vertical positions without using shield gas.

EFFECT: enhanced quality of surfaced parts.
