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...
Research on Sintering Technology of Silicon Carbide Ceramic Material
With the development of science and technology, especially the rapid development of modern national defense, aerospace, marine engineering and automobile industry, the market has higher and higher requirements for various properties of materials. Silicon carbide ceramics are widely used in precis...
Effect of Vacuum Annealing on Alloy Sheet
TC4 titanium alloy contains 6% α stable element Al and 4% β stable element V, which belongs to the typical α+β type titanium alloy of Ti-Al-V system. This alloy accounts for about 40% of the market volume of titanium alloy series, and it is very difficult to cold work, mainly because the alloy ha...
Vacuum oil quenching and tempering spring steel wire
Alloy spring steel wire is divided into three categories, alloy spring steel wire, vacuum oil quenching and tempering silicon-manganese spring steel wire, vacuum oil quenching and tempering chromium-silicon alloy spring steel wire for valves, from the current status of alloy spring use in develop...
Why use process boxes in vacuum brazing
Vacuum brazing uses a vacuum atmosphere without using flux, and realizes the connection of various easy-to-solder or difficult-to-solder materials at high temperatures. The resulting brazed joints have high quality and beautiful shapes. It is very suitable for vacuum brazing of precision parts an...
Ceramic-To-Metal Vacuum Brazing Services
With the development of science and technology and people’s increasing requirements for various properties of materials, metal-ceramic assemblies have developed rapidly in recent years and have been widely used in various fields such as national defense and aerospace. In nuclear power and s...
