Interface properties of Ti3SiC2/Al2O3 ceramics: Combined experiments and first-principles calculations

“…In the case of the 312 phase, Ti3SiC2 [23], Ti3AlC2 [24], and Ti3GeC2 [25] have been widely applied owing to their facile preparation and excellent stability. In particular, Ti3SiC2 contains strong covalent Ti-C bonds and weak metallic Ti-Si bonds, thereby resulting in a combination of ceramic and metallic properties [26,27], indicating its potential to act as a toughening phase in alumina ceramics. Recently, our group synthesized Ti3SiC2/Al2O3 ceramic composites and found a clear boundary between the Ti3SiC2 and Al2O3 crystal surfaces, in addition to improved mechanical properties compared to the Al2O3 system alone [4,28].…”

Si‐rich pressureless sintering of the gelcasted Ti3SiC2 bulk ceramic

“…M n+1 AX n phase is a class of ternary carbides and nitrides, where M denotes transition metals, A denotes elements of A‐group, X denotes either C or N, and n equals 1, 2 or 3. As a typical member of the MAX phase, Ti 3 SiC 2 also features some combined characteristics of both metal and ceramic, including high‐temperature strength, superior oxidation, corrosion and thermal shock resistance, high thermal and electrical conductivity, and excellent damage tolerance 1‐6 . Besides, Ti 3 SiC 2 is also compatible with the lead‐bismuth‐eutectic (LBE) 7‐9 .…”

Effect of TiC0.4 Addition on Microstructures and Properties of Ti3SiC2 Matrix Composites

“…Its layered crystal structure is comparable to that of well-known graphite and MoS 2 solid lubricants, implying that it may be an excellent solid lubricant material with a low friction coe cient [6]. Thus, Ti 3 SiC 2 could nd potential applications in bearings, turbines, cutting tools, electrical contacts, heat exchangers [7][8][9][10][11], etc. However, this is severely hampered by low hardness (4.54 GPa) and wear resistance (0.21-1.87×10 −3 mm 3 /N•m) of Ti 3 SiC 2 ceramics [12].…”
