In the 80s of the 20th century, the TIN coating prepared by the physical vapor phase product (PVD) method was widely used in the cutting of alloy steel and high-alloy steel, but the anti-high temperature oxidation temperature of TIN was low, and it was difficult to maintain its hardness and stability due to high temperature during high-speed processing, the appearance of Tiain coating increased the oxidation resistance of the coating to about 800C, and the appearance of the coating further improved its oxidation resistance, and the oxidation temperature of the composite Tiain CRN was as high as 900 degrees. At present, the methods for preparing composite coatings mainly include magnetron sputtering ion plating and arc ion plating deposition. The coating prepared by the former has uniform thickness and dense structure, but the deposition rate is low, the evaporation rate of arc ion plating is high, and the film-based adhesion is good, which is widely used in the industrial field.
TIN is a general-purpose PVD coating, which is the most mature and widely used hard coating material, which can improve the hardness of the tool and has a high oxidation temperature, which is suitable for high-speed steel cutting tools or forming tools to improve their machining performance.
Titanium nitride coating has good physical and chemical properties such as high melting point, good chemical stability, high hardness, good electrical conductivity, thermal conductivity and light properties, which makes it have very important uses in various fields, especially in the field of new cermets and metal decoration. There is more and more demand for nitridin powder in the industry, and nitridda is a coating ** which is both inexpensive and wear-resistant and corrosion-resistant, and its many properties are better than vacuum coatings. The application prospect of nitride bowl is very broad.
It is mainly used in the following aspects:
1) Titanium nitride is highly biocompatible and can be applied to clinical medicine and stomatology, and titanium nitride coating is used for dental implants.
2) Titanium nitride has a low coefficient of friction and can be used as a high-temperature lubricant.
3) Titanium nitride has a metallic luster, which can be used as the best gold decoration material, and has a good application prospect in the gold decoration industry; Titanium nitride can also be used as a gold coating in the jewelry industry; It can be used as a potential material to replace WCC, so that the application cost of the material can be greatly reduced. Everyday porcelain with titanium nitride coating and coloring.
4) It has super hardness and wear resistance, which can be used to develop new types of tools, which are significantly more durable and service life than ordinary carbide tools.
