Abstract

In this paper the beneficial effect of the addition of yttrium by ion implantation on the oxidation behaviour of chromium has been studied. Emphasis was placed on the initial stages of oxidation during rapid heating to 900 C. Characterization of the surface layers was carried out with two X-ray techniques at glancing angles. The short range structure of two yttrium rich oxides, Y(2)O(3) and YCrO(4), was observed. The latter is believed to represent the structure around the yttrium segregated to the oxide grain boundaries. The Y(2)O(3), present as particles, is expected to play only an indirect role by forming a source of yttrium which is slowly segregating to the grain boundaries.
