Titanium Nickel Nitride Properties:
A typical NaCl-type structure for titanium nitride powder is a cubic cubic with a lattice constant = 0.4241nm. Titanium atoms reside at the edges of this cubic. TiN is non-stoichiometric and has a stable composition range of TiN0.37-TiN1.16. It is possible to alter the nitrogen content of TiN within a specified range, but not cause structural changes.
Formula TiN, TiN is yellowish brown, while the fine TiN is black. TiN crystals are golden yellow. TiN powder has an excellent thermal shock resistance, having a melting point at 2950 degrees Celsius, a density of 5.4-5.44g/cm3, Mohs toughness 8-9 and a weight of 5.43-5.44g/cm3. TiN’s melting point is more than the most transition metal nutrides. But, it has a lower density than most metal nitrides. It is therefore very heat-resistant.
Titanium Nickel Nitride:
TiN is a relatively stable compound. At high temperatures it does not react to metals like iron, chromium or calcium. TiN Crucibles don’t react with acidic and alkaline slags under CO and nitrogen atmospheres. The TiN Crucible provides a great container for studying the interaction of molten and other elements. TiN can lose nitrogen when heated in a vacuum. This results in titanium nitride having a very low nitrogen content.
The attractive yellow colour of Titanium Nitride Powder is due to its high melting points, hardness and chemical stability. This powder can also be used in superconductivity materials as well as high-temperature structural material.
TiN, a brand new multifunctional ceramic material with excellent properties, is Titanium Nitride (TiN). Its characteristics include high melting points and hardness. Wear resistance. Good electrical and thermal conductivity. Excellent optical properties. It has an extremely high superconductivity at lower temperatures and a melting temperature of 2951-2930. It can be used in the manufacture of jet engines. Because of the advances in science and technology it has played a significant role in many different fields. Its distinctive golden-yellow metallic luster can also be used to decorate gold.
(1) In tool making
A titanium nitride ceramic coated has a golden look. While it can optimize the appearance of the coated tool, the main purpose is not decoration. It is hardened to a Webster hardness value (HV) of at least 2500. A coating of thickness 3 to 5 microns is applied on the tool. It provides greater wear resistance and heat resistance than the uncoated product. By applying this technology to machinery in industrial production (e.g. coating titanium Nitride on gear hobs), its lifespan can be extended from 3 to 4. The cutting speed and feed can be increased when cutting gears. This can help reduce the material machining times. High-speed coated tools account for 70 percent of all high-speed tool usage in developed industrial countries. To process the gears of automobiles almost all use coated high speed steel knives. Their rolling speed is 70-150 m/mm.
A major scientific and technical project was undertaken in our country by Professor LiuNing of Hefei University of Technology, School of Materials Science and Engineering. This research focused on the study of nano-TiN and AlN modified Titan carbide-based Cermet Tools. Research has demonstrated that the TiC cermet cutter, modified by nanoTiN, exhibits excellent mechanical properties. It is also a unique cutter with high technical value and high added values. This tool is also capable of partially replacing carbide tools like YC8/YT15 after more than 4 months of usage by the users. Tool life has been more than doubled and production costs are comparable or even lower to YC8 tools. My country has been able to create new cermet tools using nanomaterials. This also represents a breakthrough in the research of special ceramics.
(2) Applications in biomedicine
In clinical medicine, the occluder is used for treating congenital heart disease, atrial septal defect and ventricular septal defects. Conventional concentric obstructions, however, are usually made out of nickel-titanium alloys. These materials can contain as much as 55% nickel. It can cause allergic reactions and poisoning, which can then lead to cancer. Ordinary nickel-titanium seals can remove the protective membrane covering the nickel/titanium mixture. Due to human bodies complex environment, internal nickel ion releases can increase nickel content, which in turn leads to deterioration in tissue compatibility.
According to related research, nitride (TiN), has a high biocompatibility and is used in coronary stents. This means that thrombogenicity of the material is lower than Nickel-titanium. Xianjian Technology, Shenzhen, Ltd. has developed a Cera Ceramic Membrane Occluder using high-energy ion precipitation coating technology to solve this medical problem. Keep the original design for the nickel-titanium-alloy occluder. Use plasma technology and ion tech to apply a layer titanium nitride Tilt on top of the nickel-titanium alloy. This coating can then be used as a biological layer, increasing the resistance to corrosion and compatibility with blood and biological tissues.
Comparing Cera ceramic occluder with ordinary nickel-titanium, the results of animal experiments show that Cera ceramic occluder performs better in cell crawling and growth than ordinary nickel-titanium. This occluder can significantly improve congenital heart disease repair and decrease the risk of platelet adhesion and thrombosis. It also has a lower hemolysis rate than other nickel-titanium ones. Cera has been tested in thousands of cases with congenital hearts disease and is approved by countries around the world, such as Russia, India and Brazil.
(3) The film is applied to the block in front of the vehicle
The standard procedure for attaching heat-insulating film to a domestic vehicle is now followed by most car buyers. It is more crucial to protect the windshield at the front. Car film can block ultraviolet rays. It can heat, prevent injuries from sudden glass breaks and reduce ultraviolet radiation damage on objects and persons in cars. There are many different types of thermal insulation film for automobiles on the current market. Each has a unique material function and service life. The combination of magnetron and metal nitriding techniques create a nano-ceramic coating that uses nano-titanium nutride. They are not only strong and durable but can also be used to shield mobile phones signals. German Shaohua Technology Company, 2001 developed an optical nano-ceramic nano-ceramic film that is used to insulate marine glass, automotive, and architectural windows.
Here’s the main difference between nano-ceramic and metal insulation films.
1. There are two types of sunscreen: heat insulation and sunscreen.
While the heat dissipation in the metal film is less than the ceramic film’s, it has a general heat insulation effect and reflects more heat. Through the selective filtering function in the solar spectrum, the ceramic membrane can achieve the heat insulation purpose. It is much more efficient than the metal in heat insulation, has a lower reflection rate, and is stable.
2. Different signals passing rates
One key difference between metal and ceramic films is their barrier rate to signal. It interferes with import GPS. ETC is an electronic toll collection system that allows for the easy manipulation of different signals. The multi-layer and single layer metal films are generally separated. The multi-layer metallic film has better heat insulation but the signal shielding of the single-layer metal is much more difficult. Once the metallic characteristics have been removed, the ceramic film cannot shield the signal.
3. Different Oxidative Shelf Life
While the metal film is more difficult to oxidize and lasts slightly longer, its chemical nature is much stronger and is resistant to acid and alkali organic chemicals, so it has the potential to have a very long life expectancy. The general ceramic thermal insulation film has a shelf-life of 10 years and the metal thermal insulation movie is 5 years.
