Abstract
In laboratory conditions, prototypes of flux-cored wires of the cobalt-chromium-iron-manganese-nickel system were manufactured. For the production of flux-cored wire of the Co-Cr-Fe-Mn-Ni system, a sheath of 12Х18Н9 steel was used. The following metal powders were used as charge materials (cored wire filler): cobalt electrolytic powder (GOST 9721-79), nickel carbonyl powder (GOST 9722-97), reduced chromium powder (TU 14-5-298-99), metal manganese (GOST 9722-97). The diameter of the manufactured flux-cored wire was 4mm. Using the electric arc surfacing method using an ASAV-1250 welding tractor, surfacing of the flux-cored wire compositions under study was carried out. AN-348A welding flux was used as a protective material. The production of a full-profile sample was carried out by multi-pass surfacing until the height of the deposited layer was reached at 30 mm. Using the equipment available at the Federal State Budgetary Educational Institution of Higher Education SibSIU, the chemical composition of the deposited sample was studied, hardness and microhardness measurements were carried out. The mechanical properties were studied during uniaxial tensile testing, three-point bending, and impact strength at room temperature. Additionally, tests of the wear resistance of deposited samples were carried out using the “disc-pad” method. As a result of studying the elemental composition of the samples, it was determined that these samples contain no more than 35% of the alloying components used. The alloy of the cobalt-chromium-iron-manganese-nickel system obtained by surfacing allows to obtain a deposited layer 15% harder than the substrate. At the same time, the resulting alloy has fairly high physical and mechanical properties (impact strength, three-point bending and tensile strength). However, the wear re-sistance of the deposited coating is low, which allows us to conclude that this alloy is not advisable to use in the manu-facture or repair of products subject to impact and abrasive wear.
