Abstract

The processes of interaction of exogenous nanoparticles of refractory compounds ZrO2 with model nickel-base superalloys, containing tin, were studied. It was shown that, under laboratory conditions, the degree of tin removal in the metal after the introduction of ZrO2 nanoparticles depended on the time of isothermal holding and amounted to 11–18 rel.%. The content of various forms of zirconium after the experiments was determined and it was shown that the amount of ZrO2 removed from the metal to the interface of the phases Me-(refractory, slag, gas) was on average 50 rel.%.
