Characteristics and applications of titanium nitride

Characteristics of Titanium Nitride

The Vickers hardness of titanium nitride is 1800-2100, the modulus of elasticity is 251 GPa, the coefficient of thermal expansion is 9.35×10 − 6 K −1, and the superconducting transition temperature is 5.6 K.

Titanium nitride will be oxidized in normal atmosphere at 800 °C. Titanium nitride is brown and golden when used as a coating. According to laboratory tests, it is chemically stable at 20 °C, but it is slowly corroded by concentrated acid solutions that increase in temperature. Depending on the substrate material and surface finish, the coefficient of friction between titanium nitride and another titanium nitride surface (unlubricated) ranges from 0.4 to 0.9. The typical TiN formation has a NaCl-type crystal structure with a stoichiometric ratio of approximately 1:1; however, TiNx compounds with x in the range of 0.6 to 1.2 are thermodynamically stable.

TiN becomes superconducting at low temperatures, and the critical temperature of a single crystal is as high as 6.0 K. The superconductivity in thin-film TiN has been extensively studied, and the superconducting properties vary greatly depending on the sample preparation, until the superconductivity is completely suppressed during the superconductor-insulator transition. The TiN film was cooled to near absolute zero, turning it into the first known super insulator, and the resistance suddenly increased by 100,000 times.

Overview of Titanium Nitride

Titanium Nitride (TiN) is a very hard ceramic material, usually used as a coating for titanium alloys, steel, carbides and aluminum parts to improve the surface properties of the substrate. The Vickers hardness of TiN is 1800-2100, the modulus of elasticity is 251 GPa, the coefficient of thermal expansion is 9.35×10-6 K-1, and the superconducting transition temperature is 5.6K.

Application of titanium nitride

Titanium Nitride (TiN) is a fairly stable compound that does not react with metals such as iron, chromium, calcium, and magnesium at high temperatures. TiN crucible does not react with acidic slag and alkaline slag under CO and N2 atmosphere, so TiN crucible is an excellent container for studying the interaction between molten steel and certain elements. TiN loses nitrogen when heated in a vacuum and produces titanium nitride with a lower nitrogen content.

TiN has an attractive golden color, high melting point, high hardness, good chemical stability, low wettability with metals, high conductivity and superconductivity, and can be used in high-temperature structural materials and superconducting materials

Titanium nitride is a hard ceramic material used for coating titanium alloy, steel, hard alloy and aluminum parts. Because of its golden yellow surface, it can be used in jewelry and high-performance ceramic materials, as well as scalpels and orthopedic bone saw blades and other medical equipment. In addition, it is also used as a conductive barrier for 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 generally used for steel, hardened steel and stainless steel materials that require high wear resistance and lubricity. TiN is an important material for physical vapor deposition coatings and is very suitable for the use of 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 stripped and recoated. It can be stripped and repainted.

Manufacturing plastic packaging materials, such as PET bottles.

In the solar vacuum tube, the absorbed sunlight is very large.

The high temperature furnace is used for energy consumption.

Make artificial limbs and biological materials.

Manufacturing optical equipment in harsh environments.

Used as alloy modifier in cemented carbide.
