Silicon carbide coating technology is a method of forming silicon carbide layer on the surface of materials, usually using chemical vapor deposition, physicochemical vapor deposition, melt impregnation, plasma mixing chemical vapor deposition and other methods to prepare silicon carbide coating, silicon carbide coating has high temperature resistance, corrosion resistance, oxidation resistance, wear resistance and other excellent properties. Therefore, it is widely used in high temperature, high pressure, complex environment and other fields.
High temperature environment is an important field of application of SIC coating. Traditional materials may suffer from expansion, softening, burning, oxidation and other problems at high temperature, but the silicon carbide coating has high temperature stability and can withstand corrosion and thermal stress in high temperature environment. Therefore, it is feasible to use SIC coating technology at high temperature.
At high temperatures, SIC coatings can be used in the following areas:
First, aerospace
New space engines, rocket engines and other equipment that need to withstand high temperature and pressure environments can use silicon carbide coating to provide better thermal properties and wear resistance. In addition, in the field of large space, planetary exploration, satellite, etc., silicon carbide coating can also be applied to protect electronic equipment and control systems from high temperature radiation and particle beams.
Second, new energy
In the large cell frequency domain, silicon carbide coating can provide higher cell conversion efficiency and better stability, in addition, applied to high temperature fuel cells and other fields can provide higher battery life and efficiency, driving the development of new energy technologies.
3. Iron and Steel industry
In the iron and steel industry, in the production process under high temperature environment, furnace bricks, refractory materials and other equipment as well as metal pipes, valves and other components need high temperature, corrosion and wear resistant materials, silicon carbide coating can provide better protection performance, improve the service life of equipment.
4. Chemical Industry
In the chemical industry, the use of silicon carbide coating can protect chemical equipment from corrosion, oxidation and the influence of high temperature and high pressure, improve the service life and safety of equipment. In summary, silicon carbide coating technology can be applied to many high temperature environment, to provide better protection performance and service life, in the future, with the continuous development of silicon carbide coating preparation technology, there will be more fields of application of silicon carbide coating technology.
