Deposited metal requirements for cycled thermal-force operation were formulated. The influence of metal droplets and slag emulsion circular flow on the formation of an electroslag deposited metal structure is revealed. Micromorphology, ultimate composition and high-temperature properties of refractory deposited metal based on iron, nickel and nickel aluminide Ni3Al were studied. Nano-sized particles of intermetallic compounds of various origins are shown to increase the performance characteristics of refractory coatings in a cycled thermal-force operation at temperatures of 700 to 1100 °С.
