Abstract The technology of recycling the grinding wastes of metal cutting tool was developed using electroslag remelting, allowing producing a master alloy of the certain chemical composition. The structure and wear resistance of metal of the similar chemical composition deposited using two pilot flux-cored wires was investigated. A charge of one of the wires was prepared of the master alloy produced after wastes recycling, a charge of the second one was prepared of the appropriate ferroalloys. The investigations showed that the metal deposited using both flux-cored wires had similar structures and approximately the same wear resistance. It was established that the master alloy produced by utilization of grinding wastes production can be successfully used as a charge in surfacing flux-cored wires. 4 Ref., 3 Tables, 3 Figures.
