Rezumat

For the countries and regions, including, Far East region of Russia, which have procured mineral raw extractive more and more sharp there is a problem of production and use of materials from mineral raw materials with use of high technologies. For what make use of the concentrated streams of energy, electroslag remelting, aluminothermy, powder metallurgy, and also electricspark alloying for reception of strengthening coverings on tungsten hard alloys and other materials. The method electricspark alloying is activate accruing interest of researchers because of simplicity of its use, high durability of communication of strengthening coverings with a basis from current-carrying materials, low power consumption, ecological cleanliness. In this connection, in work process electricspark alloying tungsten hard alloys is considered and investigated by the electrode materials received by methods electroslag remelting and aluminothermy with use tungsten of mineral raw materials, and also other materials. Such researches represent practical and scientific interest, however they are absent in the literature. The methodology of the given work consists of two consecutive stages: methodology of making of a composite material with use of mineral raw materials, and uses of the received material for manufacturing of the electrodes (anodes) necessary for realisation of process electrikspark alloying tungsten hard alloys, applied after that as the cutting tool. With use the concentrate of scheelite and NiCr a method electroslag remelting have received new electrode materials К1 and К2; aluminothermy - materials Г1 and Г2; the combined method (aluminothermy, then electroslag remelting) – material. With use of the alloying electrodes received by a method aluminothermy (Mo-Cr, Mo-Cr-Тi) and the combined method (Mo-Cr-Тi) researches of efficiency of process electricspark alloying of tungsten hard alloys, alloys with various maintenance TiC are carried out. Principles of a choice of a material of alloying electrodes for electricspark alloying of tungsten hard alloys are offered. The most effective is use of alloying electrodes Mo-Cr with the maintenance ≥ 15 % TiC; for electricspark tungsten hard alloys with low maintenance TiC or without it - use Mo-Cr-Ti. The recommendatory conclusion about a choice of mineral raw materials for electrode materials at electricspark tungsten hard alloys, consists in a choice of the mineral raw materials containing Cr, Mo, Ti. At use of the received materials from mineral raw materials of Far East region as electrode materials experimental researches confirm efficiency of wear resistance tungsten hard alloys which raised on 30-40 % at cutting of a steel 45.
