The influence of implanted yttrium on the mechanism of growth of Cr2O3 on Cr

One of the apparent effects of Y on the growth of Cr2O3 scales, based on inert marker studies, is a change in growth mechanism from predominant cation diffusion to predominant anion diffusion (1-3). The interpretation of inert marker studies has always been open to question, and a recent study of th...

Summary:One of the apparent effects of Y on the growth of Cr2O3 scales, based on inert marker studies, is a change in growth mechanism from predominant cation diffusion to predominant anion diffusion (1-3). The interpretation of inert marker studies has always been open to question, and a recent study of the mechanisms of growth of alpha-Al2O3 scales using 18O tracer techniques (4) has demonstrated that the results of inert marker studies can, indeed, be misleading. Results of 18O tracter oxidation experiments conducted with Y-implanted and Y-free Cr are reported in this paper, which demonstrate that Y implantation does change the mechanism of oxide growth.
