Titanium Nitride Properties
Titanium Nitride Powder has a typical NaCl-type structure. It is a facecentered cubic with a lattice coefficient of 0.4241nm. Titanium Atoms are at the top corner of the facecentered cubic. TiN, a nonstoichiometric material, has a stable composition range between TiN0.37 and TiN1.16. Within a specific range, the nitrogen content of TiN can be altered without affecting its structure.<br />
Titanium Nitride Formula TiN. TiN Powder is yellowish-brown in color, ultrafine TiN Powder is black and TiN Crystal is golden yellow. TiN has a melting range of 2950°C and a Mohs Hardness of 8-9. It also has a good thermal shock resistance. TiN’s melting point is higher than the majority of transition metal Nitrides. But its density is less than most metal Nitrides. This makes it a unique heat-resistant substance.<br />
Titanium nitride Uses:
TiN (Titanium Nitride) is a stable compound, which is why it is used to study the interactions between molten iron and certain elements. TiN Crucibles are also resistant to acidic and alkaline slags under CO and nitrogen atmospheres. TiN can be produced with a low nitrogen content by heating it in a vacuum.<br />
Titanium Nitride Powder has an attractive golden-yellow color, high melting temperature, high hardness and chemical stability. It is also a superconductor and electrical conductor with high electrical conductivity.
The new multifunctional cermet titanium nitride material (TiN) has many excellent properties such as a high melting point, a high hardness and wear resistance, chemistry stability, electrical and thermal conductivity and good optical characteristics. Its melting temperature is between 2930-2950. This material is good at conducting heat and electricity and is superconducting at low temperatures. It is used in the manufacture of jet engines. As science and technology progress, its role has changed. Titanium nitride’s unique golden metallic luster allows it to be used for gold decoration.<br />
The ceramic titanium nitride coating is golden in appearance. The coating has the advantage that it optimizes the appearance of the tool. However, its primary function is not to decorate. It has an HV value of Webster 2500 or more. The thickness of the coating is 3 to 5 m, which provides greater wear resistance and heat resistance as well as a longer life span than the original tool. This technology can extend the life of mechanical equipment used in industrial production by up to four times. It can also increase the speed at which gears are cut or fed. Coated high-speed instruments account for 70% of all high-speed equipment in industrialized countries. In almost all automotive industries, coated high-speed knives are used to process gears. The rolling speed can be as high as 70-150m/mm.<br />
In 2005, Professor Liu Naning of the School of Materials Science and Engineering of Hefei University of Technology hosted a large national scientific and technical project to study modified titanium carbide based cermets using nano-TiN and AlN. The research shows that a TiC-based titanium carbide cutter modified by nanoTiN is a cutter with excellent mechanical properties. This new type of tool has high technical content, and demonstrates a high added value. In addition, the tool’s performance in cutting processes has been proven to be comparable with carbide tools, such as the YT15 and YC8. The tool life is doubled, while the cost of production is similar to or slightly less than that of YC8. This research has allowed the development of new cermet tool made from nanomaterials, in my own country. It is also a new step in the study and application of special ceramics.<br />
(2) Biomedical applications
Clinical medicine has widely used the occluder to treat congenital heart diseases such as atrial septal defect, ventricular septal defect, and patent arteriosus. The majority of conventional concentric occluders, however, are made from nickel-titanium material, which contains up to 55% Nickel. Excessive nickel can cause allergies or poisoning in the human body. It can also lead to cancer over the long term. In the complex human body environment, the internal nickel ion release will increase the content of nickel, which further leads to the deterioration of the tissue compatibility of the occluder.<br />
Related research shows that because titanium nitride (TiN) is a material with good biocompatibility (once used for coronary stents), thrombogenicity is much lower than nickel-titanium itself. As early as 2004, Xianjian Technology (Shenzhen) Co., Ltd. developed a Cera ceramic membrane occluder using high-energy ion precipitation coating technology for this medical problem. Based on the design of the original nickel-titanium alloy occluder Maintain the design of the original room septal occlusion device, interventricular septal occlusion device, and arterial catheter occlusion device, using plasma technology to uniformly wrap a layer of titanium nitride TiN film on the surface of its nickel-titanium alloy, using ion technology to make the metal The combination of titanium coating and C, N, O, etc. is converted into a biological coating, which greatly improves the corrosion resistance of the occluder and the compatibility of biological tissue and blood.<br />
According to the animal experiment data comparison between Cera ceramic membrane occluder and ordinary nickel-titanium occluder: Cera ceramic membrane occluder is far superior to ordinary nickel-titanium occluder in terms of cell crawling growth performance. Improving the repair of congenital heart disease defects while significantly reducing the risk of thrombosis, platelet adhesion, and hemolysis rate is also much lower than ordinary nickel-titanium occluders. At present, the Cera occluder has been approved by regions and countries, including the European Union, India, Brazil, and Russia, and has been used in thousands of patients with congenital heart disease.
(3) Application of the film on the front block of the car
Today’s domestic car owners seem to have become the standard for attaching a heat-insulating protective film to their car after purchasing a car. The film in the main radiation area of the car’s front windshield is even more important. After all, the car film has a part that blocks ultraviolet rays and blocks. Heat and prevent injuries and glare caused by the sudden burst of glass and reduce the damage caused by ultraviolet radiation in objects and people in the car. At present, there are many types of automobile thermal insulation films on the market, which are different in material function, service life, and effective presentation. Based on nano-titanium nitride, the combination of magnetron sputtering technology and metal nitriding technology produces a nano-ceramic film which is not only durable, not easy to corrode, but also has the advantages of not shielding mobile phone signals and good heat dissipation, product performance To a large extent, and it is superior to other types of automotive insulation films. The earliest nano-ceramic insulation film is an amber optical nano-ceramic insulation film developed by German Shaohua Technology Company in 2001, which is used in marine, architectural, and automotive glass films.<br />
The difference between nano-ceramic insulation film and metal insulation film is as follows:<br />
1. Sunscreen and heat insulation are different
The heat dissipation of the metal film is worse than that of the ceramic film, the heat insulation effect is general, and the reflection rate is higher. The ceramic membrane achieves the purpose of heat insulation through the selective filtering function of the solar spectrum. The heat insulation is far more than the metal, the reflection rate is lower, and the stability is excellent.<br />
2. Different signal passing rates
A key difference between the metal film and the ceramic film is the barrier rate to the signal. The metal film interferes with imported GPS. It is also an ETC (non-stop electronic toll collection system), which is easy to affect the passage of various signals. The metal film is generally divided into a single layer The metal film and the multi-layer metal film, although the multi-layer metal film is superior to the single-layer metal film in heat insulation, because of its deeper thickness, the signal shielding becomes more serious. The ceramic film will not shield the signal after removing the metal characteristics.<br />
3. Different oxidative shelf life
The metal film is easy to oxidize, and the shelf life is slightly shorter, while the chemical nature of the ceramic film is relatively stable, it is not easy to oxidize, and it can withstand acid and alkali organic solvents, which can have a long service life. The shelf life of general ceramic thermal insulation film is ten years, and that of the metal thermal insulation film is five years.<br />
