What Is The Pressure On A Vacuum Furnace?
Vacuum solid solution treatment requires a high degree of vacuum (1.33×10-2~1.33×10-3Pa); in order to prevent the evaporation of alloy elements, vacuum partial pressure treatment should be used, that is, the vacuum in the heating chamber should be evacuated to 1.33×10-2~1.33×10-3Pa, and then back...
Tips for setting partial pressure values in vacuum heat treatment
Metal elements in pure metals and alloys will evaporate under certain temperatures and vacuum levels. It has a harmful impact that cannot be ignored on the quality of vacuum heat treatment of parts and the pollution of the vacuum heating chamber. According to the phase equilibrium theory, the eq...
Minimize deformation in high temperature vacuum
Vacuum heat treatment deformation will cause serious losses to the accuracy obtained in the early processing of the workpiece. These losses are sometimes difficult to recover even through complex and advanced modification techniques (gear grinding, alignment, etc.). This will directly affect the ...
What is Vacuum Brazed Diamond
Vacuum brazed diamond tools have attracted great interest in research and product development from industry experts and manufacturers because of their high connection strength and high cutting edge. At present, Ni-Cr-B-Si solder is mostly used to braze diamond to make single-layer diamond tools. ...
What Are The Advantages Of Vacuum Sintered Materials?
As an important structural ceramic material, silicon carbide is used in high-temperature kiln furniture and combustion nozzles due to its excellent high-temperature mechanical strength, high hardness, high elastic modulus, high wear resistance, high thermal conductivity, corrosion resistance and ...
High-vacuum brazing of Mg-bearing aluminum alloys
In vacuum brazing, at a specific temperature, the middle layer of solder melts, wets, and spreads in the gap between the base metals, filling the gaps and completing the connection to the base metals through capillary action. During the vacuum brazing process, the original shape of the base metal...
New vacuum sintering method
Vacuum hot pressing sintering Hot press sintering applies axial pressure to the green body based on the traditional sintering method, so that the ceramics can obtain additional mechanical energy during the sintering process and promote the sintering densification process. The external stress duri...
Exploring Different Types of Vacuum Sintering Techniques
In recent years, improving densification has been a research direction that has attracted much attention in the field of special ceramics. The degree of densification often plays a crucial role in its properties, especially its mechanical properties. The first method is to adjust the composition ...
What Is Vacuum Brazing? Process,Benefits,& More
Vacuum brazing furnace flux Flux is also called flux. In metallurgy, it is a substance that uses chemical methods to clean the surface of the metal to be welded to facilitate soldering, brazing, or positioning welding. Different fluxes are used to weld different metals. According to the classific...
Vacuum brazing quick guide
The so-called brazing refers to a welding method that uses a metal material with a lower melting point than the base metal (material to be welded) as a solder, and uses the solder that melts into a liquid state to infiltrate the base metal and fill the interface gap between the workpiece and diff...
