Abstract

Interdiffusion, intrinsic, tracer and impurity diffusion coefficients are calculated in the Pd-Pt system. Interdiffusion coefficients are more or less insensitive to composition change. Activation energy varies in the range of 324-353 kJ/mol. Impurity diffusion coefficients calculated in this study and available tracer diffusion coefficients in pure elements indicate that Pd has higher diffusion rate compared to Pt in pure Pd, whereas, both the elements have similar diffusion rates in Pt. Kirkendall marker experiments indicate that Pd has much higher diffusion rate in Pd3.5at.%Pt compared to Pt.
