Gear steel high temperature carburizing process
The carburizing process is a traditional manufacturing process for service parts to obtain high hardness surfaces and strong toughness matching the core. The purpose is to improve the load-bearing capacity and service life of the parts, and ensure that the carburized parts have high load-bearing ...
Working principle of ceramic vacuum sintering furnace
Vacuum sintering furnace plays a very important role in the preparation process of advanced ceramics. Vacuum sintering is a key link in the preparation process of advanced ceramics. Its function is to heat-treat the formed ceramic green bodies at high temperatures to promote the bonding and densi...
The Basics of Aluminum alloy vacuum brazing
Vacuum brazing uses an alloy material with a lower melting point than the base metal as the filler metal. The base metal and the filler metal are clamped together with a clamp, and heated in a vacuum furnace to melt the filler metal into a liquid state. The liquid filler metal is in the gap or be...
Detailed explanation of vacuum sintering process
Various powdery iron-containing raw materials are mixed with an appropriate amount of fuel and flux, and an appropriate amount of water is added. After mixing and pelletizing, the materials undergo a series of physical and chemical changes on the vacuum sintering equipment, and the mineral powder...
Ceramic metal vacuum brazing process flow
Ceramics and metals are the main materials. Ceramics generally use ceramic materials with high temperature stability and good thermal expansion coefficient matching, such as alumina, silicon nitride, etc. Metal materials need to be selected with good compatibility and creep properties with cerami...
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...
