Abstract

This paper presents mathematical simulation of diffusion and chemical phenomena accompanying the formation of the transition zone between a silicon coating and a titanium nickelide substrate under nonisothermal conditions. The grains and their boundaries in the substrate are considered as separate phases with different diffusion properties. The study accounts for the formation kinetics of a three-component solution. In the case of micrograins, the size of the boundary phase is small as compared with that of the bulk phase. In the case of nanograins, the sizes of the phases are comparable, which is responsible for the distinctive features in the formation of the transition zone composition.
