1. Preparation of nano powder by arc method
Under vacuum conditions, the principle of arc discharge is adopted, and the powder material is vaporized under arc discharge conditions to make nano powder, and nano powder is collected after capture, powder is collected after collection (glove box), purification, oxidation, liquid protection and other completion processes are completed in the powder collection process. At present, it is widely used in engine lubrication, military industry, etc.
2. Vacuum low temperature vulcanization
Under vacuum conditions, sulfur is evaporated and deposited on the surface of the workpiece by the principle of high-pressure discharge. At the same time, due to the plasma generated around the workpiece, the surface of the workpiece is activated, and some sulfur ions penetrate into the workpiece. Because it is under vacuum conditions, the temperature can be made very low, and the time is also short, to achieve its purpose.
At present, this technology is widely used in friction bodies, such as rolling steel, roller friction, body and other dry grinding places, and must be used in the absence of lubricants.
3. Vacuum carburizing, nitriding equipment (glow nitriding furnace)
Under vacuum conditions, negative high pressure is applied to the workpiece, and at the same time it is filled with reactive gas or acetylene and other gases. Because the workpiece has negative high pressure, a glow discharge is generated in the vacuum furnace, which ionizes the gas and activates the surface of the workpiece, so the surface material of the workpiece is modified, so as to achieve nitriding, carbonization (nitriding),
4. Vacuum diffusion furnace
Under vacuum conditions, the plated workpiece, through high-temperature conversion, the use of the plated material in the high temperature further diffusion to the metal structure on the surface of the workpiece, so as to achieve good adhesion, low stress, and give full play to the coating effect.
5. Vacuum brazing furnace
Under vacuum conditions, two workpieces are melted by heating solder to weld the two workpieces together. The usual practice is: in the vacuum through high-frequency induction heating to heat the welding to reach the solder welding temperature to weld, the advantage of this method of welding is that the welding is firm without welding defects, is the current more ideal welding. Its disadvantages are low efficiency and large input costs. Therefore, it is mainly used in extremely demanding parts, such as military industry, aerospace and aviation.
6. Vacuum exhaust table
The vacuum principle is used to discharge the gas inside the container. At present, the company has a solar collector vacuum exhaust table. Various exhaust stations can also be designed on request.
