Application of vacuum brazing heat treatment technology
Advantages of vacuum brazing technology Vacuum brazing is an advanced welding method in which the workpiece is in a vacuum state, that is, in a negative pressure atmosphere, the solder is heated into liquid by a heat source, and the gaps between solid parts are filled by the action of capillaries...
Application of powder metallurgy degreasing and sintering in stainless steel parts
Metal Injection Molding (MIM) is a new type of powder metallurgy net forming technology that introduces plastic forming technology into the field of powder metallurgy. It is one of the hot spots in the current research of advanced manufacturing technology. The high-performance special-shaped meta...
Vacuum brazing: precision connection technology in the microscopic world
Vacuum brazing is a connection process performed in a vacuum environment. The basic principle is to use a filler metal (i.e., brazing material) with a lower melting point than the base material, heat it to a temperature higher than the melting point of the brazing material and lower than the melt...
Application characteristics of vacuum brazing
Vacuum brazing technology can be rapidly developed and applied, mainly because it has a series of advantages compared with other welding methods. (1) During the entire brazing process, the brazed parts are in vacuum conditions (10-2Pa ~ 10 Pa range), and there will be no oxidation, expansion, dec...
Maintenance of Vacuum Heat Treating Furnaces
Regular maintenance measures for vacuum heat treatment furnaces: Vacuum pump maintenance: Mechanical vacuum pumps need to regularly replace lubricating oil, clean the pump cavity, check the wear of the vanes and rotors, etc., to ensure stable pumping performance; Diffusion vacuum pumps need to re...
How is the vacuum degree of the sintering furnace achieved?
Sintering furnace is a kind of equipment used to heat and sinter powder materials to densify them and form materials or products with specific properties, and vacuum is an extremely critical environmental factor in its operation. To create a vacuum environment in the sintering furnace, a vacuum s...
Do you know what are the main uses of vacuum sintering furnace?
The vacuum sintering furnace uses a high-temperature vacuum sintering furnace for the vacuum sintering process of samarium cobalt, aluminum nickel cobalt, metal mesh, cemented carbide, ceramic materials, optoelectronic coating materials, graphite purification, magnet materials and rare refractory...
Let you know about vacuum furnace process gas
Design principles of vacuum furnace: The principle of vacuum furnace design is to extract the ambient air in the furnace at the beginning of heat treatment, and at the same time, process gas can be introduced to reach a specific pressure below atmospheric pressure. Therefore, the vacuum furnace c...
Problems that should be paid attention to in vacuum brazing
Vacuum heating is accompanied by the release of surface adsorbed gas, volatilization and release of water, decomposition and release of organic matter such as oil, decomposition or reduction of oxide film and oxide, precipitation and release of gas elements in metal, volatilization of metal eleme...
Vacuum brazing furnace failure and troubleshooting methods
The vacuum brazing furnace is the key to ensure the stable operation of the equipment and the quality of brazing. The following is classified according to common fault types, and provides cause analysis and solutions: Vacuum system failure The vacuum system is the core to ensure the normal operat...
