Use of Titanium Coated Film

Titanium thin film is generally used to improve the wear resistance of objects. For example, taps and drill bits for high-speed machining centers can be coated with titanium to improve the wear resistance of the tool, and the surface treatment of the piston ring is also titanium-plated, also in order to improve the wear resistance.

The titanium film not only has a very high wear resistance, but also has good decorative and aesthetic properties. The color of the titanium film is golden. After coating with a thin titanium film, the object can prevent oxidation, rust, etc.



Commonly used titanium coating processes
1. Titanium coating processes: vacuum coating and spraying process.
The vacuum coating includes: magnetron sputtering method, arc ion plating method, evaporation method, etc. Titanium sputtering targets are indispensable raw materials in the vacuum coating process.
The method of spraying is cold spraying.
Both coating methods have their own advantages. The advantage of vacuum coating is that the film it coated is very thin, and has high compactness and excellent performance. While the biggest advantage of spraying is that it is cheap. However, the coating is very thick to the order of millimeters and the surface roughness requires subsequent processing.

What kind of gas does the magnetron sputtering titanium need?
1. When a metal film is applied, argon gas is generally used as a working gas. It is an inert gas, and does not undergo oxidation when the substrate is heated under vacuum. Generally speaking, argon gas is used to adjust the pressure of the furnace body, and the effect on color is not obvious!
2. Oxygen is generally used for plating non-metallic films, such as TiO2, and there is no need to worry about membrane oxidation after plating.
3. Nitrogen is the gas that is flushed into the vacuum chamber when the target coating is changed, so that the pressure in the vacuum chamber and the atmospheric pressure are kept equal, and the other film can be plated for the target. Nitrogen generally increases the yellow b value, such as zirconium, which is golden yellow!


What color can the titanium film form through different gases?
1. TiN (gold)
2. TiZrN (Gold)
3. TiC, TiNc (bright gray ~ gun black)
4. TiNC (rose gold ~ brown)
5. TiO (gem blue ~ iridescent)

六方晶窒化ホウ素および立方晶窒化ホウ素 (Hexagonal Boron Nitride and Cubic Boron Nitride)

2019年06月20日 | Advanced ceramics
In recent years, new materials based on ceramics have developed rapidly. Boron nitride ceramic is a kind of hexagonal crystal system with phosphorus structure and special physicochemical properties. It is a new industrial material developed with the development of the aerospace and electronics industry and has a wide range of applications in industry and production.

At present, research on boron nitride is mainly concentrated on the hexagonal phase (h-BN) and the cubic phase (c-BN). Hexagonal boron nitride has good lubricity, thermal conductivity and high temperature performance. Recent studies have shown that the hexagonal phase is also in thermodynamic equilibrium and steady state at room temperature and pressure. The main application of hexagonal boron nitride is to act as a raw material for the synthesis of cubic boron nitride.



Hexagonal boron nitride is called white graphite because it has a similar layered crystal structure and physical and chemical properties similar to graphite (good lubricity and thermal conductivity). Hexagonal boron nitride is commonly used as a sintered ceramic material. In addition, due to its high thermal conductivity, good electrical insulation properties, low thermal expansion coefficient and non-thermal properties, h-BN structural ceramics have been widely used in high temperature insulation components, atomic energy, metallurgy, aviation and other fields. As a raw material for synthesizing cubic boron nitride, hexagonal boron nitride is a theoretical low-temperature stable phase, and its excellent performance is more attractive. Therefore, hexagonal boron nitride is commonly used to synthesize cubic boron nitride.

Boron nitride ceramics have excellent thermal stability and dielectric properties. They are one of the few compounds that can decompose at high temperatures, and have excellent thermal and electrical stability even over a wide temperature range. However, single-phase boron nitride ceramics have not been put to practical use due to low strength, hardness, elasticity, high thermal conductivity, low corrosion resistance, and difficulty in forming a shape component.
As an advanced ceramic material, boron nitride is widely favored in the field of materials research due to its excellent mechanical properties. The new boron nitride synthesis method has become a hot topic in boron nitride research.
