Successful operations include a titanium pelvis implanted into a British patient, titanium lower jaw transplanted to a Dutch patient, [50] and a plastic tracheal splint for an American infant. [51] The hearing aid and dental industries are expected to be the biggest areas of future development using custom 3D printing technology. [ 52 ]
The coefficient of thermal expansion of cemented tungsten carbide is found to vary with the amount of cobalt used as a metal binder. For 5.9% cobalt samples, a coefficient of 4.4 μm/m·K was measured, whereas 13% cobalt samples have a coefficient of around 5.0 μm/m·K.
Titanium nitride (TiN) is a refractory solid exhibiting extreme hardness, thermal/electrical conductivity, and a high melting point. [13] TiN has a hardness equivalent to sapphire and carborundum (9.0 on the Mohs scale), [14] and is often used to coat cutting tools, such as drill bits. [15]
Ilmenite is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. Ilmenite is the most important ore of titanium [5] and the main source of titanium dioxide, which is used in paints, printing inks, [6] fabrics, plastics, paper, sunscreen, food and cosmetics.
Ceramic armor is armor used by armored vehicles and in personal armor to resist projectile penetration through its high hardness and compressive strength. In its most basic form, it consists of two primary components: A ceramic layer on the outer surface, called the "strike face," backed up by a ductile fiber reinforced plastic composite or metal layer.
Titanium diboride (TiB 2) is an extremely hard ceramic which has excellent heat conductivity, oxidation stability and wear resistance. TiB 2 is also a reasonable electrical conductor, [ 1 ] so it can be used as a cathode material in aluminium smelting and can be shaped by electrical discharge machining .
