Titanium diboride (TiB2) materials have garnered significant attention due to their remarkable comprehensive properties. They offer potential applications in high-temperature structural materials, cutting tools, armor, electrodes for metal smelting, and wear-resistant parts. However, due to the low self-diffusion coefficient, the TiB2 exhibits poor sinterability, excessive grain growth at elevated temperatures, and inadequate oxidation resistance, limiting its wide application. Therefore, many research works are devoted to processing TiB2 at a lower sintering temperature and improving the properties through various sintering additives and more advanced techniques. This article comprehensively reviews the multiple synthesis methods and sintering technologies of TiB2, and at the same time, critically discusses the impacts of sintering additives and reinforcing agents on densification, microstructure, and various properties, including those at high temperatures, and finally predicts the future development of TiB2 composite materials.

“…On the basis of the previously presented results [12,13], the selection of input powder materials and methods of preparation for ceramic-based bulk TiB 2 /Ti composites, intended for high-temperature PVD coatings, was made. Samples were prepared to obtain the composite with Ti/TiB 2 , with the ratio of 15/85 wt% in a fully reacted state.…”

“…To minimize these drawbacks, our approach proposes utilization of self-propagating high-temperature synthesis (SHS) or combustion synthesis for fabrication of the powder feedstock representing a collection of “pomegranate-like” particles consisting of TiB particulates bonded/clued by titanium. SHS has been widely accepted for production of various materials including ceramics, composites, and intermetallic and nano-phase materials [ 16 , 17 ] due to its high efficiency, negligible energy consumption, short processing time, and high productivity. It utilizes the advantages of extreme heat generated by the exothermic reaction in a reactive mixture during processing, resulting in the formation of a needed solid product [ 6 ].…”

Titanium alloys and composites are of great interest for a wide variety of industrial applications; however, most of them suffer from poor tribological performance, especially at elevated temperatures. In this study, spark plasma sintering was utilized to produce a fully dense and thermodynamically stable TiB–Ti composite with a high content of ceramic phase (88 wt.%) from self-propagating high temperature synthesized (SHS) powders of commercially available Ti and B. Microstructural examination, thermodynamic assessments, and XRD analysis revealed the in situ formation of titanium borides with a relatively broad grain size distribution and elongated shapes of different aspect ratio. The composite exhibits a considerable hardness of 1550 HV30 combined with a good indentation fracture toughness of 8.2 MPa·m1/2. Dry sliding wear tests were performed at room and elevated temperature (800 ℃) under 5 and 20 N sliding loads with the sliding speed of 0.1 m·s−1 and the sliding distance of 1000 m. A considerable decline in the coefficient of friction and wear rate was demonstrated at elevated temperature sliding. Apart from the protective nature of generated tribo-oxide layer, the development of lubricious boric acid on the surface of the composite was wholly responsible for this phenomenon. A high load bearing capacity of tribo-layer was demonstrated at 800 ℃ test.
