Abstract

The kinetic regularities of growth and lateral spreading of an intermetallic layer along a free surface during surface interdiffusion in binary systems have been studied both theoretically and experimentally. A quasi-stationary solution for concentration distribution on the surface of growing intermetallics as well as kinetic equations of lateral spreading and profile evolution of growing phase layer have been obtained. By comparison of experimental data on intermetallic growth kinetics with the proposed theory, the surface diffusion constants have been calculated for intermetallics NiMo and Cd₂₁Ni₅.
