AbstractThermal stability of Ti3AlC2 at 1250-1400 degrees C in 10%CO-Ar atmosphere has been investigated. Decomposition of Ti3AlC2 occurs when the temperature is 1250 degrees C. After the treatment at 1300-1400 degrees C, nanoscale aluminum oxycarbides (Al2OC and Al4O4C) were formed on the sample surface due to the reaction between Al and CO. At 1250-1300 degrees C, a mixture layer of Ti(O,C) and Al2O3 was formed; while at 1350-1400 degrees C, the reaction scale below the nanoscale aluminum oxycarbides are a duplex layer with a porous Ti(O,C) inner layer and a mixture of Ti(O,C) and Al-containing compounds outer layer. The outward extraction of Al and Ti along some special planes, i.e., {0 0 0 1} and {11-20} of Ti3AlC2, is believed to result in the orderly arranged pores in the inner porous Ti(O,C) layer.
