Abstract
Bulk and grain boundary diffusion of titanium in yttria fully stabilized zirconia was studied in air in the temperature range from 1200 to 1400 degrees C. The secondary ion mass spectrometry (SIMS) technique was used to determine the diffusion profiles in the form of mean concentration vs depth in B-type kinetic region. In order to confirm that the diffusion occurred in the chosen kinetic regime the 3-dimensional distribution of titanium was also determined. The obtained results allowed to calculate the temperature dependence of the bulk diffusion coefficient D and the grain boundary diffusion parameter D'delta s. Activation energies of these processes amount to 505 and 340 kJ mol(-1), respectively.
