Pd diffusion in Rh has a great interest in the 103Pd production for brachytherapy, a cancer treatment using radioactive implants. In order to study that diffusion, DC-magnetron sandwich layers of natural Pd and Rh were produced, annealed, and the Pd profiles were measured by Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS). The interdiffusion profiles were then analysed using the InverseMethods MatLab© code developed at the Rensselaer Polytechnic Institute. Four different methods were applied to our data: Boltzmann-Matano (BM), Sauer-Freise-den Broeder (SFdB), Error function series approximation (ERF), and Fourier series source approximation (Fourier). Pd/Rh and Rh/C interdiffusion coefficients are calculated for different temperatures and the results are shown.
