Vacuum Hardening Strengthening Process for Low Carbon Steel
Some parts in the textile machine were originally made of malleable cast iron, which had low mechanical properties and often broke during work. 20 steel vacuum hardening was used to replace the original malleable cast iron material. The actual operation proved that the service life was increased ...
The characteristics and working principle of vacuum heat treatment furnaces
Vacuum heat treatment is a kind of heat treatment process. As long as it involves the field of mechanical manufacturing, heat treatment is a widely used and very important basic process. Metal materials after vacuum heat treatment can give full play to their performance potential, which is very i...
Maintenance of Vacuum Carburizing Furnaces
The application of vacuum carburizing treatment technology has spread to all walks of life, and it is one of the indispensable heat treatment methods in industrial development. The surface of the workpiece after vacuum carburizing treatment is smooth, with high mechanical properties and long serv...
Applied Crack Repair Technology of Vacuum Brazing
Speaking of the perception of soldering, the scene of connecting electronic components with electric soldering iron and tin wire will appear in everyone’s mind, which is the most common welding method in soldering connection. Brazing is divided into hard brazing and soft soldering according...
Vacuum carburizing process of transmission gear
The vacuum carburizing process that carries out carburizing treatment under reduced pressure has many advantages such as no grain boundary oxidation, no abnormal carburized layer on the surface of the workpiece, shortened heat treatment time, less exhaust gas, and energy saving. It is the most su...
Vacuum Heat Treatment of Carbon Boron Steel Fasteners
The greater the hardenability of the steel, the greater the yield ratio after quenching and tempering. The increase in the yield ratio means that the potential of the steel can be better utilized. It is necessary to meet the tensile strength and yield ratio specified for motorcycle products. High...
Correct use and maintenance of vacuum brazing furnace
In the vacuum furnace, it is estimated that it is used for brazing to account for about 10%. A large number of early products mainly meet the strict requirements of aerospace products, and the trend in recent years has shifted to general industrial applications. Vacuum brazing produces cleaner, f...
Overview of Vacuum Hardening Furnace
1.1 Overall design of vacuum hardening furnace Vacuum hardening furnace is mainly composed of furnace body (including quenching oil tank), evacuation system, heating power supply, control cabinet and so on. The furnace body is a horizontal structure, and the material is loaded and unloaded in the...
Influence of Vacuum Brazing Process on Microstructure of Tungsten and Steel
Tungsten has the characteristics of high melting point, high hardness, high wear resistance and low vapor pressure. It is not only a rare metal, but also a strategic metal. It has a wide range of applications, such as hard alloys, high-strength wear-resistant alloys for aerospace rockets, alloys ...
Silicon carbide module silver sintering technology
SiC modules face several technical challenges, including reliability and heat dissipation. For this reason, the silver sintering process is very popular, and some companies have also developed a copper sintering process. In 2006, Infineon Easypack1 used double-sided silver sintering technology; i...
