Titanium Nitride (TiN) is an extremely hard ceramic material

Risk aversion plunged on the positive news of the Russia-Ukraine talks. After several days of rising oil prices, the price of precious metals continued to fall. Domestic futures markets remain stable for the time being.

Back in international markets, WTI crude futures briefly dipped below $100 a barrel, while Brent crude hit its lowest intraday level in nearly two weeks. Spot gold briefly fell below $1,900 an ounce. Comex gold futures closed down 1.1 percent at $1,918.4 an ounce. Comex silver futures closed down 1.14 percent at $24.91 an ounce. "Recently, crude oil prices have been extremely sensitive to changes in geopolitical news." Traders believe that the current oil price is still in the broad impact, Ukraine will still be a premium in the case, although the market further decline, but should not be too pessimistic, it is recommended to wait and see for the time being. The Ukrainian premium is still there and there will be some volatility in the Titanium Nitride TiN market.

Overview of Titanium Nitride TiN

Titanium nitride TiN (sometimes called Tinite) is an extremely hard ceramic material commonly used as a coating for titanium alloys, steel, carbide and aluminum parts to improve the surface properties of the substrate.

As a thin coating, TiN is used 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, a coating of less than 5 microns (0.00020 inches) is applied.

TiN has a Vickers hardness of 1800–2100, an elastic modulus of 251 GPa, a thermal expansion coefficient of 9.35 × 10-6 K-1, and a superconducting transition temperature of 5.6 K. In normal atmosphere, TiN oxidizes at 800 °C. TiN is brown in color and golden when used as a coating. According to laboratory tests, it is chemically stable at 20°C, but it is slowly attacked by concentrated acid solutions as the temperature increases. The coefficient of friction of TiN to another TiN surface (unlubricated) ranges from 0.4 to 0.9, depending on the substrate and surface finish. Typical TiN formation has a NaCl-type crystal structure with a stoichiometric ratio of about 1:1; however, TiN x compounds with x ranging from 0.6 to 1.2 are thermodynamically stable. TiN becomes superconducting at low temperature, and the critical temperature of single crystal is as high as 6.0 K. Superconductivity in thin-film TiN has been extensively studied, and its superconductivity properties vary from sample preparation to complete suppression of superconductivity at the superconductor-insulator transition. The TiN film was cooled to near absolute zero, turning it into the first known superinsulator, with a sudden 100,000-fold increase in resistance.

Application of Titanium Nitride TiN

A well-known use of TiN coatings is for edge retention and corrosion resistance in machine tools such as drills and milling cutters, often increasing their lifespan by a factor of three or more. Due to the metallic gold color of TiN, it is used to decorate the coating of costume jewelry and automotive trim. TiN is also widely used as a top coat, typically on nickel (Ni) or chrome (Cr) plated substrates for consumer sanitary equipment and door hardware. As a coating, it is used in aerospace and military applications to protect the sliding surfaces of bicycle and motorcycle suspension forks and the shock shafts of radio-controlled automobiles. TiN is also used as a coating for the moving parts of many rifles and semi-automatic firearms. Protective coating as it is very durable. In addition to being durable, it is also very smooth, making it very easy to remove carbon deposits. TiN is non-toxic, complies with FDA guidelines, and has applications in medical devices such as scalpel blades and orthopedic bone saw blades, where sharpness and edge retention are important. TiN coatings are also used to implant prostheses (especially hip replacement implants) and other medical implants.

Although less obvious, TiN films are also used in microelectronics, where they act as conductive connections between active devices and metal contacts used to operate circuits, while acting as a diffusion barrier to prevent metal from diffusing into silicon. In this case, TiN is classified as a "barrier metal" (resistivity ~25 µΩ cm), although it is clearly a ceramic from a chemical or mechanical behavioral point of view. Recent chip designs using 45 nm technology and beyond also use TiN as the "metal" to improve transistor performance. Combined with gate dielectrics with higher dielectric constants (such as HfSiO) compared to standard SiO 2, gate lengths can be reduced while having low leakage, higher drive currents, and equal or better threshold voltages. In addition, TiN films are currently being considered for coating zirconium alloys for fault-tolerant nuclear fuels. Due to their high biostability, TiN layers can also be used as electrodes in bioelectronic applications, such as in smart implants or in vivo biosensors that must withstand severe corrosion caused by bodily fluids. TiN electrodes have been used in subretinal prosthesis projects as well as in biomedical microelectromechanical systems (BioMEMS).

Where is the best place for humans to live in outer space? So far, the moon is more habitable in outer space, and it is likely to be turned into a planet. However, whether humans can live on the moon for a long time, these questions have always been lingering in everyone's minds, always There is no way to get an answer. According to the report, a team from the University of Aeronautics and Astronautics in Beijing, after nearly 370 days of closed life, finally simulated the life experiment on the moon, and finally knew what the final truth was. Live here for a long time.

All aspects of human beings are constantly improving, and the demand for Titanium Nitride TiN is also increasing.If you are engaged in the Titanium Nitride TiN industry, you just happen to contact us.
