摘要：

We report the results of our experiments on cyclic exposure of Ti3SiC2 ceramics to CO environment at high temperature. The growth of a two-layer scale composed of a dense outer layer containing beta-SiC and TiC microcrystals, and a porous inner layer of TiC microcrystals was observed. The corrosion was accompanied by the release of SiO gas, which then took part in the growth of beta-SiC microcrystals in the upper part of the outer layer by the reaction with CO gas.
