Oxidation of monolithic TiB2 and TiB2–20wt.% MoSi2 composite at 850°C

Correlation between phase evolution, mechanical properties and instrumented indentation response of TiB2-based ceramics

“…[1][2][3][4] This unique combination of properties renders TiB 2 -based materials suitable for a wide range of technological applications, such as armor materials, wear components, conductive coatings, cathode materials the possibility of obtaining dense TiB 2 -based cermets at lower temperatures, the presence of metallic sinter-additives result in significant degradation of the high temperature properties and corrosion resistance of TiB 2 .…”

Oxidation Kinetics and Mechanisms of Hot‐Pressed TiB2–MoSi2Composites

“…As far as the oxidation resistance of TiB 2 in the presence of Si 3 N 4 sinter‐aid is concerned, parabolic weight gains were observed for TiB 2 ‐2.5 wt% Si 3 N 4 composite at T <1000°C and this was attributed to the formation of TiO 2 and B 2 O 3 ( l ) on the surface 25 . Recently, we reported preliminary oxidation studies of monolithic TiB 2 and TiB 2 ‐20 wt% MoSi 2 composite for longer duration (64 h) at 850°C 33 . Koh et al 34 reported the improved oxidation resistance of TiB 2 due to coating of protective amorphous SiO 2 layer on the surface.…”

“…For high temperature applications of TiB 2 , understanding the oxidation behavior of the materials is one of the most important aspects. In view of this, considerable research efforts are invested to study the oxidation behavior of TiB 2 materials 25–37 . However, the study of sintering additive effect on high temperature oxidation of TiB 2 is limited.…”

In situ Reaction Synthesis and Mechanical Properties of TaC–TaSi2 Composites

“…It has been proved that MoSi 2 possesses excellent oxidation resistance and high‐temperature mechanical properties 26–30 . In previous reports, MoSi 2 was successfully used as the additive to densify the poor‐sintering ceramics, such as ZrB 2 , HfB 2 , TiB 2 , and ZrC 31–34 . Similarly, it is promising for TaSi 2 to densify TaC.…”
