Study on reaction and diffusion in the Mo-Si system by ZrO2 marker experiments

Abstract

The dominant diffusing element in the MoSi2, Mo5Si3 and Mo3Si was found to be Si from marker experiments using ZrO2 particles. Based on these marker experiments, the formation mechanism of the Mo5Si3 and Mo3Si layers by reaction and diffusion was also discussed.
