Vacuum Brazing Process of Slide Valve Sub-assemblies
Vacuum brazing is a process method for welding parts without applying flux in vacuum. It can be used for materials and structures that are difficult to weld. It can obtain smooth and compact brazed joints with excellent mechanical properties and corrosion resistance, and the thermal stress of the...
Alternate Vacuum Brazing Process for Aluminum Alloy Materials
With the development of avionics systems, the requirements for airborne electronic equipment are getting higher and higher, and the chassis of airborne electronic equipment is required to have a complex and compact structure, strong electrical and thermal conductivity, high heat conduction effici...
The situation and solution of the scrapped vacuum furnace
1.The thermocouple breakdown product is scrapped Phenomenon and reasons: When brazing and heating, the high temperature breaks down the thermocouple tube shell. The thermocouple conduction temperature display record is noticeably inaccurate. The atmosphere enters the furnace with the tube shell, ...
MIM Process Equipment
Metal Powder Injection Molding (MIM for short) is a near-net-shape forming technology formed by introducing modern plastic injection molding technology into the field of powder metallurgy. The basic process of MIM is shown in the figure: firstly, the solid powder and organic binder are uniformly ...
Vacuum heat treatment process of automobile gearbox gears
Gearbox gears are located in the transmission part of the car and are used to transmit torque and power and adjust speed. Due to the transmitted torque, the tooth root To withstand large bending stress and alternating stress; due to the wide range of gear speed changes in the gearbox, the gear su...
Carbide vacuum brazing
For the development and application of cemented carbide, quality is becoming more and more important, but in the process of vacuum welding in some manufacturers, some problems often occur, such as cracks. The root cause of vacuum brazing cracks is that the tensile stress generated during the vacu...
Selection of Quenching Cooling Medium
Quenching is the most critical process in the heat treatment process, which ultimately determines the inherent quality and distortion of the quenched parts. Quenching and cooling technology has been continuously improved with the development of heat treatment technology from beginning to end. How...
Tool vacuum brazing
Brazing is a type of welding process that is widely used in many industries. In the welding process of the tool making process, the brazing process is mostly used. The definition of brazing: adding solder (solder) between two or more workpieces to be welded, heating to melt the solder, and formin...
Aluminum alloy vacuum brazing process
Due to the characteristics and advantages of vacuum brazing, it is widely used. If the vacuum brazing process is selected for complex and precise aluminum alloy brazing, the vacuum brazing process can be formulated for the brazing of such parts before brazing. And inspection rules, but also need ...
Vacuum heat treatment of 20CrMnTi steel
20CrMnTi is a low carbon alloy steel with high mechanical properties, and the surface of the parts is carburized 0.7-1.1mm. After carburizing quenching and low temperature tempering, the surface hardness is 58-62HRC, and the core hardness is 30-45HRC. The process performance of 20CrMnTi is better...
