摘要：

We have studied the desilicidation of Ti3SiC2 MAX phase powder at 1600 degrees C in a CO + xSiO (x = 0, 1, 1.5, 2, 3) gas atmosphere. The required gaseous atmosphere was generated using granulated powder mixtures containing commercial carbon, TiO2, SiO2, and SiC, which released CO and SiO gases during heating as a result of oxide reduction reactions. Ti3SiC2 desilicidation was sensitive to the gas phase composition and occurred only if the CO : SiO ratio exceeded 1 : 3 (x < 3). The Ti3SiC2 desilicidation process was shown to be reverse of TiC silicidation with SiO gas and could be described by the following chemical reaction scheme: Ti3SiC2 + CO(g) = 3TiC + SiO(g).
