Abstract

The influence of an initial preinternal oxidation treatment in Co/CoO on the subsequent oxidation behavior of a series of dilute Co-Cr alloys (containing 0–1.5 wt. % Cr) in 105 and 103 Pa oxygen at 1473–1623 Khas been investigated. Particular emphasis has been placed on determining the solubility and mobility of Cr3+ ions in CoO. Use has been made of subsequent annealing in argon\((p_{O_2 } - 10^{ - 1} {\text{ }}Pa)\).
