The kinetics of oxidation of hypereutectic alloys based on nickel and ZhS32 with titanium carbide at 1100°С is studied, and their melting temperature and heat resistance are determined. The content of carbide in alloys is 30% by volume (19% by weight). As found, the growth of the alloy mass on the basis of alloyed nickel is significantly lower in contrast to the alloy based on ZhS32 at annealing for 50 hours in air at 1100°С. The depth of corrosion damage of the nickel alloy surface after the annealing is also smaller, compared with the depth of damage of the alloy on the basis of ZhS32. As shown, the high heat resistance of the alloy based on nickel with titanium carbide is due to the optimal doping complex.
Key words: nickel alloys, titanium carbide, melting point, heat resistance.
