Arc evaporation deposition is a common method for workpiece mechanical abrasion treatment. However, this method is easy to produce particles of impurities and the quality of the film can not be guaranteed.
To solve this problem, China has developed a new filtered cathodic vacuum arc coating zinc oxide technology. This patented technology can not only be applied to high-quality amorphous tetrahedral carbon membrane, but also other film metallization and metal oxides. The finished products fully meet the stringent conditions in the actual production.
Cathodic vacuum arc coating process, the cathodic arc ion beam emission (mixed macro-particles and neutral atoms). Electromagnetic filter elbow is responsible to filter out unnecessary macro-particles and neutral atoms, only those with a certain energy ion Scientology piece. This particular technology can produce a harder, denser, more pure film. FCVA method plated film: higher binding capacity and the substrate; good optical, chemical, electronic and mechanical properties; and reproducible, and fully meet various production requirements.
In addition, the coating process, the surface temperature of the substrate can generally be kept below 70 . Therefore, you can FCVA coating of plastic or rubber. With traditional methods (for example: chemical vapor deposition, physical vapor deposition) FCVA technology to produce energy stability of the arc and 100% pure ion beam energy according to different requirements for precise control. Through this technology can produce ta-C film, and can produce high-quality Al2O3 film.
Comparing with other similar technologies, FCVA technology’s advantages are: ion beam energy adjustable nature of the film can be selected and fine-tuning. Therefore, the binding force of the film and the titanium dioxide substrate better the nature of the film is more stable. Through such as ion scanning patented technology, the coating has superior uniformity and repeatability, and large area coating, which are similar technologies beyond the reach of. The FCVA technologies used to produce much less macro particles. Ta-C film, compared to other similar technologies per square centimeter of about 103 FCVA coating per square centimeter contains only about a macro-particles. Such coating equipment has been successfully applied to the hard sliding head surface coating and other friction and mechanical fields of application. FCVA technology also contains a set of complex electromagnetic field of the anode / cathode area, the cathode and anode size adjustable, to ensure that the output of plasma for the bundle. This large area of high deposition rate of coating is particularly important. FCVA technology is a low temperature process, the coating process can be controlled below 70 ° C. The coating process does not require high temperatures will not produce high temperature. Therefore, it can be applied to a variety of low- temperature melting of the substrate, such as plastics, rubber and so on.Source:http://www.mhcocm.com
The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
