High temperature oxidation of MgO composites with Ni particle dispersion
- 1. Nagaoka University of Technology, Nagaoka, Niigata (Japan). Department of Mechanical Engineering
Description
Oxidation behavior of MgO-based composites with 5 vol% Ni particle dispersion was investigated at high temperatures in air. Oxidized layer consisted of (Mg,Ni)O solid solution and includes voids. Growth kinetics of the oxidized layer followed the parabolic law, which meant that mass transport in the oxidized layer was rate-controlled. The apparent activation energy of the parabolic rate constant agreed with that of the extrinsic diffusion coefficients of Mg and Ni.
