摘要：

Chromium diffusion in alumina single crystals was studied in the temperature range 1000-1500 degrees C. Diffusion profiles were determined by the SIMS technique at depths less than 1 mu m. The bulk diffusion coefficients were obtained from the first parts of the profiles. The results are discussed in the Light of theoretical and other experimental results. The second parts of the profiles are explained by dislocation-enhanced diffusion.
