Why Switch to Brazing in the Vacuum Furnace
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...
High temperature vacuum furnace application introduction
A high-temperature vacuum furnace is a specialized piece of equipment that is widely used in materials science, chemistry, physics, and many industrial fields, especially where precise control of reactions or processing environments is required to achieve specific material performance requirement...
Understand the Advantages of Vacuum Heat Treatment
Vacuum heat treatment removes the air from the furnace so that the workpiece is heated and cooled in a vacuum state. Compared with vacuum heat treatment, controlled atmosphere heat treatment has lower cost and is easy to use. It is one of the current development directions of heat treatment. Its ...
What are the advantages of vacuum heat treatment?
Compared with conventional heat treatment, the mechanical properties (especially plasticity and toughness) of metal material workpieces after vacuum heat treatment have been significantly increased. The reason is that the vacuum heat treatment has a good degassing effect. Surface purification and...
Why should heat treatment furnaces be vacuum sealed?
The importance of vacuum sealing The chemical activity of the high vacuum atmosphere is extremely low. During vacuum heat treatment, the reactions that occur at the interface between the gas phase and the solid phase, such as oxidation, reduction, decarburization, carburization, etc., will not pr...
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 ...
