Titanium carbide, Ti C, is an extremely hard (Mohs 9–9.5) refractory ceramic material, similar to tungsten carbide. It has the appearance of black powder with the sodium chloride ( face-centered cubic ) crystal structure .
Some of them, including titanium carbide and tungsten carbide, are important industrially and are used to coat metals in cutting tools. [ 3 ] The long-held view is that the carbon atoms fit into octahedral interstices in a close-packed metal lattice when the metal atom radius is greater than approximately 135 pm: [ 2 ]

The first cemented carbide developed was tungsten carbide (introduced in 1927) which uses tungsten carbide particles held together by a cobalt metal binder. Since then, other cemented carbides have been developed, such as titanium carbide, which is better suited for cutting steel, and tantalum carbide, which is tougher than tungsten carbide. [1]
Titanium silicon carbide, chemical formula Ti 3 SiC 2, is a material with both metallic and ceramic properties. [1] [2] It is one of the MAX phases. See also.
Titanium is a chemical element; it has symbol Ti and atomic number 22. ... Titanium carbide (TiC), which is also very hard, is found in cutting tools and coatings.
Materials include M50 tool steel (AMS6491), carbon chrome steel (AMS6444), the corrosion resistant AMS5930, 440C stainless steel, silicon nitride (ceramic) and titanium carbide-coated 440C. [ 1 ]
Kennametal, a metal-working and tool company based in Latrobe, PA, USA, developed the first titanium carbide cermet with a 19 megapascals (2,800 psi) and 100-hour stress-to-rupture strength at 980 °C. Jet engines operate at this temperature and further research was invested on using these materials for components.
