Internal Oxidation of Dilute Co-Ti Alloys.
Abstract
The kinetics of internal oxidation of Co-Ti alloys and the crystal structures and morphologies of the internal oxide particles have been investigated in the temperature range 900 to 1080C. Three oxides were observed: sigma-TiO, TiO2 (rutile) and CoTiO3. The permeabilities of oxygen in Co were calculated from the observed internal oxidation kinetics using an analysis due to Meijering and an analysis based on a more rigorous solution of the diffusion equations. The factors affecting the size and morphology of internal oxide particles are discussed.
