FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy, particularly, to powder wire for making of heat-resistant coating by arc metallisation for parts operated at high-temperature gaseous corrosion. Powder wire for application of said coatings on said parts composed of steel shell and core. To up heat-resistance of applied coatings the core is made of the charge containing the following elements in wt %: aluminium powder "ПА4" 3-7%, metal chromium "Х99Н1" 23-27%, ferrotitanium "ФТи70С05" 0.5-1.2%, ferrosilicum "ФС90" 0.8-1%.
EFFECT: higher heat resistance.
