“…As a filler were used corresponding powder materials: iron powder brand PJV 1 by GOST 9849-86, ferrosilicon powder brand FS 75 by GOST 1415-93, powder of high carbon ferrochrome brand FH900А by GOST 4757-91, powder of carbon ferromanganese FMn 78(А) by GOST 4755-91, nickel powder PNK-1L5 by GOST 9722-97, ferromolybdenum powder brand FMo60 by GOST 4759-91, tungsten powder brand PVP-1 by TI 48-19-71-78, ferrovanadium powder brand FV50U 0.6 by GOST 27130-94, cobalt powder brand PK-1U2 by GOST 9721-79. As a carbon-contained component was used carbon-fluorine contain material (CFCM) that was previously used in works [18][19][20][21] with the following chemical composition, wt.%: Al 2 O 3 = 21-46.23; F = 18-27; Na 2 O = 8-15; K 2 O = 0.4-6; CaO = 0.7-2.3; Si 2 O = 0.5-2.48; Fe 2 O 3 = 2.1-3.27; C obsh = 12.5-30.2; MnO = 0.07-0.9; MgO = 0.06-0.9; S = 0.09-0.19; P = 0.1-0.18. Surfacing under the AN-26S flux was conducted in 6 layers on samples of the 09G2S grade steel with its 16mm thickness.…”

In the article is shown the comparative analysis between structures of surfaced by the flux coded wire metal systems Fe-C-Si-Mn-Cr-Ni-Mo-V and Fe-C-Si-Mn-Ni-Mo-W-V. These powder wires are supposed to be used in recovering details and equipment components and machines, that works in conditions of intensive abrasive – shock wear. Manufacturing and surfacing of flux cored wires samples were made in laboratory conditions. Defined chemical composition of the surfaced metal. Deposited metal samples hardness and wear resistance were researched. In the course of deposited meta surface metallographic analysis were made following metallographic researches: defined nature and level of nonmetallic oxides impurity, type and morphology of the microstructure, grain size of surfaced samples. Estimation of the chemical composition components influence on the hardness and wear resistance were obtained.

The possibility of producing flux-cored wires based on dust from gas cleaning plant of aluminum production, silicon and aluminum powders (as a reducing agent) and gas cleaning dust from ferrochrome production (as a reducible component – chromium oxide) was studied. In the laboratory conditions samples of flux-cored wires were produced, surfacing, hardness measurement, abrasion rate and metallographic studies were performed.

Alloys of the Fe‒C‒Si‒Мn‒Сr‒W‒V system widely used for hot-rolling roll repairs provide high resistance of the deposited layer against abrasion, but its thermal endurance is relatively low. It is shown that in order to ensure the quality of roll repair, it is necessary to improve the composition of the flux-cored wire charge and the technology of their use. It is proposed to reduce the structural heterogeneity of the deposited metal the use of flux-cored wire of the type PP-Np-35V9X3SF. The influence of the introduction of carbon-fluorinated elements and titanium on hydrogen concentration, microstructure, level of pollution by non-metallic inclusions, grain size, hardness and rate of wear of the deposited metal layer was evaluated. The data on the chemical composition of the deposited layer, the content of non-metallic inclusions in it, the microstructure of the deposited metal, depending on the content of titanium in the flux-cored wire, are presented. It was found that an increase the concentration of titanium increases the hardness of the deposited layer and reduces the rate of wear (abrasion) of samples. The effect on the level of contamination of the studied fused layers with oxide inclusions was not revealed. Increasing the hydrogen content in the deposited layer re-duces its hardness and increases the rate of wear of the deposited layer. Increasing the content of titanium in the depos-ited layer helps to reduce the size of the martensite needles, as well as the size of the former austenite grain. The de-pendencies of HRC hardness and wear resistance on the content of titanium and hydrogen in the deposited layer were established
