“…Firstly, Ti (~300 mesh, purity: 99.9%), Si (~300 mesh, purity: 99.9%), Al (~300 mesh, purity: 99.9%), and graphite (~300 mesh, purity: 99.99%) powders in a molar ration of 3:1:0.2:2 was used as the raw material for the fabrication of Ti 3 (SiAl)C 2 powders. In this regard, a small amount of Si was substituted by Al to eliminate TiC impurities and improve its oxidation resistance 6,25,26 . All the elemental powders were placed in an agate ball mill jar and mixed uniformly by planetary ball milling.…”

Adjusting the grain growth orientation may be a feasible way to improve the oxidation resistance. In this work, textured Ti3(SiAl)C2 ceramic was successfully fabricated via the spark plasma sintering technique. The crystal orientation and microstructure were investigated by XRD combined with EBSD. The oxidation behavior of textured Ti3(SiAl)C2 was investigated at 1000–1300 °C for 10 h. The results showed that the oxidation was significantly anisotropic and the surface parallel to the compression direction exhibited better oxidation resistance below 1200 °C. The improved oxidation resistance was primarily attributed to the formation of passivated Al2O3 scale by rapid out-diffusion of Al elements on the orientated (hko) planes in textured Ti3(SiAl)C2. The formation of oxide scales was strongly dependent on the crystallographic orientation of Ti3(SiAl)C2.

Considering the lack of an effective anti-oxidation protective layer for the oxidation process of Ti3SiC2, an in situ synthesis of Ti3SiC2 and Al2O3 was designed. Thermally stable Al2O3 was used to improve the high-temperature oxidation resistance of Ti3SiC2. Samples without TiC were selected for the oxidation test, and the oxidation morphology and weight gain curves of the oxidized surface in air at 1400 °C are reported. The change in the oxidation behavior occurred 4 h after oxidation. The addition of Al2O3 changed the composition of the oxide layer and compensated for the lack of a dense protective layer during Ti3SiC2 oxidation. Moreover, after 4 h of oxidation, the newly generated Al2TiO5 and the composite layer formed by diffusion were the main reasons for the large difference in the final weight gain between the two sets of samples.
