Bartek Wierzba, Marek Danielewski, Katarzyna Tkacz-Śmiech and Jan Sieniawski The Growth Kinetics of Nickel Aluminide Coatings by the Bi-velocity Method Chemical Vapor Deposition 18
The problem of simultaneous growth and competition of intermediate phases is presented. The volume continuity equation is used to compute the material velocity in a reacting system in which reactions occur at several moving interfaces. The growth of multiphase layers is show. The CVD process and annealing in a non-oxidizing atmosphere are simulated. The kinetics and concentration profile of the reactive diffusion in an Al-Ni system are compared with experiments.
