English abstract:
Two methods which are used for calculation of diffusion coefficients in multiphase binary systems are outlined and compared - the investigation of layer growth kinetics and the fitting of concentration profiles. The methods are discussed in view of their particular advantages and disadvantages and illustrated on the non-metal diffusion coefficients in the Nb-N, Nb-C, Cr-N, Cr-C Ta-N and Ta-C systems. It is shown that the best way for determining the non-metal diffusivity in multiphase systems is the combined refinement of diffusion coefficients employing both the layer growth enhancement and the concentration profile fitting.
