Powder high-temperature materials based on nickel alloys for strengthening parts of hot zones of metallurgical units

A considerable part (up to 50%) of the cost of metallurgical production is determined by the repair cost of equipment and spare parts. In this connection the problem of increasing the wear resistance of rapidly worn parts of metallurgical units operating under extreme conditions under the effect of heating, stresses, aggressive media, and other harmful factors will always remain urgent. One of the ways for solving the problem consists in creating a protective layer with elevated wear and oxidation resistances on the functional surfaces of such parts. The present work is devoted, to the determination of the service life of heavily loaded parts of hot zones of continuous casting machines (CCM).
