Experimental investigation and computer simulation of diffusion in Pt-coated bulk Ni
The concentration profiles of thin-film Pt/bulk Ni coatings annealed at 1150, 1250 and 1300°C for different time were measured by means of electron probe microanalysis. The corresponding interdiffusion coefficients were then determined using the thin-film solution. The calculated concentration p...

| Summary: | The concentration profiles of thin-film Pt/bulk Ni coatings annealed at 1150, 1250 and 1300°C for different time were measured by means of electron probe microanalysis. The corresponding interdiffusion coefficients were then determined using the thin-film solution. The calculated concentration profiles based on the presently obtained interdiffusion coefficients agree well with the experimental ones, but better at a higher temperature or a longer time. The comparison between the presently measured concentration profiles and the DICTRA simulated ones indicates that it is promising to apply the well-established atomic mobility databases due to bulk diffusion information in coating systems with some simple modifications for diffusivities. |
