It’s Time for Another Look at Vacuum Oil Quenching
Factors affecting the appearance of vacuum quenched workpieces Vacuum quenching often has high requirements for appearance. There are many factors that affect the appearance of vacuum quenching workpieces, including: vacuum degree, air leakage rate, cooling medium characteristics, materials, etc....
Vacuum Furnace with Oil Quench
Hardening of steel is one of the main heat treatment processes. In this process, which is initially carried out using aqueous solutions, the quenching medium affects the final properties of the steel and can therefore be controlled to optimize the hardness, microstructure and degree of deformatio...
Vacuum Oil Quenching Effects on Gear Distortion
Vacuum furnaces are used for quenching. Small parts with relatively large workpieces, quenching temperatures below 1000°C, and relatively high hardenability are intended to be quenched with oil. There are following requirements for vacuum quenching oil: (1) The vapor pressure is low and not easy ...
Study on the Process of Vacuum Low Pressure Carburizing
The product quality of vacuum carburizing is better than that of controlled atmosphere furnace carburizing. For gear carburizing that needs to control quenching deformation, after carburizing in controlled atmosphere furnace, it is necessary to use a quenching press to perform quenching and corre...
Why Vacuum Heat Treatment is a Good Idea
It has the following characteristics in high vacuum: 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, carburizatio...
What is the vacuum sintering method
Vacuum sintering is a special heat treatment process. Its purpose is to turn porous powder compacts into alloys with certain structures and properties. Sintering is the last step in the production process of cemented carbide. The structure and properties of the alloy are of course It depends on m...
Comparative study on vacuum nitriding and carburizing processes
Nitriding is a chemical heat treatment process that penetrates nitrogen atoms into the surface of the workpiece in a certain medium at a certain temperature. Commonly used are liquid nitriding, gas nitriding, and ion nitriding. Traditional gas nitriding is to put the workpiece into a sealed conta...
Introduction to vacuum brazing process of aluminum and aluminum alloys
Aluminum alloy liquid cooling plate With the widespread application of liquid cooling technology in various industries, there is a huge demand for aluminum alloy liquid cooling plates. Among the welding processes of various aluminum alloys, the brazing process occupies a very important position ...
Vacuum Furnace Brazing Process
Basic principles of vacuum brazing Brazing refers to a welding method in which the solder is melted by heating (above 450°C, but lower than the melting temperature of the base metal), and the capillary action of the liquid solder is used to fill the solder joint and mutually diffuse with the base...
Advantages of vacuum nitriding furnace for mold materials
Vacuum pulse nitriding furnace, vacuum nitriding furnace, referred to as nitriding furnace or nitriding furnace, is used for surface nitriding or nitrocarburizing of various aluminum molds, extrusion dies, screws, screw rods and other spare parts, especially suitable for There are nitriding treat...
