Titanium Nitride (TiN) is a very hard ceramic material, usually used as a coating for titanium alloys, steel, carbides and aluminum components to improve the surface properties of the substrate. The Vickers hardness of TiN is 1800-2100, the elastic modulus is 251 GPa, the coefficient of thermal expansion is 9.35×10-6 K-1, and the superconducting transition temperature is 5.6K.
TiN will oxidize at 800°C at normal temperature. TiN is brown and appears golden when it is coated. According to laboratory tests, it is chemically stable at a temperature of 20°C but will be slowly corroded by concentrated acid solutions at high temperatures. Depending on the material and surface finish of the substrate, the friction coefficient between TiN and another TiN is 0.4 to 0.9 TiN surface (unlubricated). The typical TiN formation has a NaCl-type crystal structure with a stoichiometric ratio of about 1:1. However, TiNx compounds with x in the range of 0.6 to 1.2 are thermodynamically stable. Titanium nitride melting point is 2950 degree.
TiN becomes superconducting at low temperatures, and for single crystals, for titanium nitride coating, the critical temperature is as high as 6.0K. The superconductivity in thin-film TiN has been extensively studied, and its superconductivity varies greatly depending on the sample preparation until the superconductivity in the superconductor-insulator transition is completely suppressed. Cooling the TiN film to an absolute value close to zero, converting it into the first known super insulator, suddenly increased the resistance by 100,000 times.
Titanium nitride is a hard ceramic material used as a coating on titanium alloys, steel, carbides and aluminum parts. Because of its golden surface, it can be used for jewelry and high-performance ceramic materials, as well as medical equipment such as scalpels and plastic bone, saw blades. In addition, it is also used as a conductive barrier in microelectronics and electrodes in bioelectronic applications.

Chemical Composition of Titanium Nitride
Titanium nitride can be made by directly reacting titanium and nitrogen at 1200°C. The coating can be formed by a vapor deposition method using a mixed gas of titanium tetrachloride, nitrogen, and hydrogen. Titanium dinitride is obtained by heating metallic titanium in nitrogen or ammonia at 900-1000°C. Titanium tetranitride is obtained by heating titanium tetrachloride in ammonia at 1000°C.

In addition, it is also used as a conductive barrier in microelectronics and electrodes in bioelectronic applications.
TiN is used as a thin coating to harden and protect cutting and sliding surfaces, for decorative purposes (due to its golden appearance), and as a non-toxic exterior for medical implants. In most applications, the applied coating thickness is less than 5 microns (0.00020 inches).
TiN is usually applied to steel, hardened steel and stainless steel materials that require high wear resistance and lubricity. TiN is an essential material for physical vapor deposition coatings and is very suitable for applications that use expensive tools (such as injection molding, sawing, tapping, and molding).
The coating is also used in many medical (implants, surgical instruments, etc.) and food processing applications. TiN can be easily peeled off and can be recoated. Can be stripped and recoated.
