Abstract Internal oxidation pretreatments of Co-15wt%Cr and Co-15wt%Cr-1 wt% Ti were carried out using a Rhines pack in quartz, in mullite, and in alumina. A dispersion of titanium oxide particles formed in the Ti-containing alloy as a result of the internal oxidation. However, silicon also diffused into all treated specimens when the pretreatments were carried out in quartz or in mullite. The effect of various pretreatments on the subsequent oxidation of these alloys was studied at 1,000°C and compared with that of a Co-15wt%Cr-1wt%Si alloy. The main purpose of this study was to determine the relative effectiveness of the dispersed oxide particles and the contaminated silicon on the selective oxidation of chromium. It was found that the oxidation behaviors of both treated alloys were strongly affected by the degree of silicon contamination. Selective oxidation of chromium to form a nearly continuous protective Cr2O3 scale was achieved with greater than 0.4 wt% silicon. The presence of dispersed particles reduced initial oxidation rate but was ineffective in promoting Cr2O3 scale formation.
