The secret of golden luster: Why does titanium nitride shine in the medical and decorative world?
Titanium nitride (TiN), this golden ceramic material, is not only famous for its hardness and corrosion resistance in the industry, but also shows its unique charm in the medical and decorative fields. It has a wide range of applications, from mechanical cutting tools to biomedical equipment, TiN can provide added value, making us wonder what the secret of this golden luster is.
Titanium nitride has a Vickers hardness of 1800 to 2100, making it an indispensable material in industry.
TiN is mainly manufactured through physical vapor deposition (PVD) technology, such as sputter deposition or electron beam heating. It can also be produced through chemical vapor deposition (CVD). In a high-energy vacuum environment, pure titanium reacts with nitrogen to form thin films. These thin films are applied to a variety of substrates to improve their surface properties and wear resistance. In addition, due to its golden appearance, TiN is also widely used in decorative coatings to add a sense of luxury to products such as clothing accessories and automotive trim.
The material's resistance to corrosion and wear has made it a popular treatment choice for machine tools, which can increase the life of these tools by more than three times. Titanium nitride is also used in aerospace and military applications and is found in shock-absorbing elements on bicycles and motorcycles, where its durability protects mechanical properties under extreme conditions.
In addition to its industrial applications, titanium nitride has also become an important material for biomedical equipment because it complies with FDA standards.
In the medical field, TiN is widely used in surgical blades and electric saw blades required for orthopedic surgeries due to its non-toxicity. These instruments need to be kept sharp during surgery, and the use of TiN can effectively maintain the edge of the knife. Furthermore, thin films of TiN play a key role in microelectronics, providing conductive connections and acting as diffusion barriers to prevent metal from diffusing into the silicon.
With the continuous development of medical technology, the application prospects of titanium nitride are becoming more and more extensive. In many implantable prosthetics and joint replacement surgeries, TiN coatings can improve corrosion resistance and increase the biological stability of the material. This makes TiN also play an important role in bioelectronic applications such as smart implants and in-body biosensors.
According to reports, various commercial variants of titanium nitride, such as titanium carbon nitride (TiCN) and titanium aluminum nitride (TiAlN), have been widely used since 2010. These variants further improve its corrosion resistance and hardness.
In addition, titanium nitride can also be used in the compression drive diaphragm of some tools, which not only improves performance but also brings a beautiful appearance to the product. In the past few years, in-depth research on titanium nitride has made these variant materials more widely used, and can provide different colors and properties. They can be seen in sports equipment, knives and pistols.
However, behind these glamorous applications, the manufacturing of titanium nitride is not easy. Processing methods such as physical vapor deposition and chemical vapor deposition require extremely high energy and vacuum environments to ensure the quality and uniformity of the film. A TiN coating that is too thick may fall off due to insufficient adhesion, so the manufacturing technology of the film is particularly critical.
In the future, with the advancement of science and technology, titanium nitride may play a role in a wider range of fields, especially in the fields of safety and biomedical electronics, and may even be used in new nuclear energy fuels.
When we discuss the various uses of titanium nitride in the medical and decorative fields, should we also think about the scientific principles and future potential behind it? What changes can these outstanding materials bring to our lives?< /p>
