Abstract: A powder electrode strip for surfacing with a wear-resistant alloy consisting of steel shell filled with a powdered mixture containing the following components in appropriate proportions to the total weight of the powder electrode strip: from 12 to 13 wt.% metallic chromium; from 20 to 22 wt.% iron powder; from 0.2 to 0.3 wt.% graphite; from 1 to 1.2 wt.% ferrochromium with a 0.6-0.8 wt.% carbon content; crystalline silicon or silicocalcium evaluated in terms of silicon at 0.6 to 0.8 wt.%; from 14 to 16 wt.% metallic manganese; from 2 to 3 wt.% titanium dioxide, from 0.6 to 1 wt.% titanium powder, and the balance is now represented by the steel shell.

Abstract: A powder-cored strip electrode for surfacing with abrasion-resistant composite alloys, is made up of a metal casing filled with a powdered charge, with said metal casing being made, according to the invention, from copper or a copper-base alloy comprising 0.2-29.5 weight per cent nickel, or from a copper-base alloy containing nickel in combination with 0.3-1.8 weight per cent aluminum and 0.3-13.0 weight per cent manganese, taken separately or in combination, and the powdered charge comprises in weight per cent of the total weight of the electrode tungsten carbides 45-70 with the remaining material being nickel, manganese, magnesium, aluminum, flourinated polymers, titanium and nickelic oxides.______________________________________ tungsten carbides 45-70 nickel 0.3-10.5 manganese 0.5-11.0 magnesium 0.2-1.0 aluminum 0.2-1.0 fluorinated polymers 1.5-3.0 titanium 0.3-0.6 nickelic oxides 0.5-1.
