Overview of Titanium Nitride

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

Physical and chemical properties of titanium nitride TiN powder Nitriding

Titanium is a synthetic ceramic material with extremely high hardness, approaching that of diamond. Titanium nitride is chemically stable at room temperature, but will be attacked and oxidized by hot concentrated acid at atmospheric pressure of 800 °C. It has infrared (IR) reflective properties, and its reflection spectrum is similar to that of gold (Au), giving it a yellowish color.

The relative coefficient of friction of titanium nitride is about 0.4-0.9 (unlubricated) depending on the base material and base surface finish. Its typical crystal structure is sodium chloride type (the relative stoichiometric ratio of elements is about 1:1), and the thermodynamic stability coefficient X of the TiNx complex is 0.6-1.2. The world's first super-insulating material is made from a thin film of titanium nitride cooled to near absolute zero, adding 100,000 insulating units.

Is titanium nitride stronger than steel?

Is titanium nitride stronger than steel?

When titanium is alloyed with other metals such as aluminum or vanadium, it is much stronger than many steels. In terms of strength, the best titanium alloys are superior to low- and medium-grade stainless steels. However, the highest grades of stainless steel are stronger than titanium alloys.

However, titanium has the highest strength-to-weight ratio of any known metal. Titanium has the same strength as steel but is 45% lighter.

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 basic slag under CO and N2 atmosphere, so TiN crucible is an excellent container for studying the interaction of molten steel with certain elements. TiN loses nitrogen when heated in a vacuum, producing titanium nitride with a lower nitrogen content.

TiN has an attractive golden yellow color. Titanium nitride (TiN) has high melting point, high hardness, good chemical stability, low wettability with metals, high electrical conductivity and superconductivity. Titanium nitride (TiN) can be used in high temperature structural materials and superconducting materials.

Titanium nitride is a hard ceramic material used for the coating of titanium alloys, steel, carbide and aluminum parts. Because of its golden-yellow finish, it can be used in jewelry and high-performance ceramic materials, as well as scalpels and orthopedic bone saw blades and other medical devices. In addition, it is 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 commonly used in 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 ideal for applications that use expensive tooling (such as injection molding, sawing, tapping, and forming).
