Abstract : The study concerns the process of thermal diffusion calorization of niobium alloys with titanium (from 5 to 50 wt. percent), the redistribution of components in both the alloy and coating, and the 'Ascending' diffusion of titanium into the coating, which is explained by the high diffusion mobility of titanium and the thermodynamic characteristics of its interaction with aluminum. The resistance of the coating to oxidation at 1100 and 1200 degrees C has been analyzed and the composition of the corrosion products of the alitized alloys determined. (Author)
