Vacuum Heat Treatment of Fasteners
We all know that the vacuum heat treatment of fasteners can make them have a certain strength, good plasticity, toughness, etc., and then they can be used better, while reducing the phenomenon of relaxation and ensuring the quality and reliability of fasteners. Vacuum heat treatment is the most c...
Vacuum sintering of transparent ceramics
In the preparation process of transparent ceramics, in addition to the key link of preparing nano-powders with high purity, uniform particle size and good activity, the molding and vacuum sintering processes are also crucial. The most commonly used molding methods for transparent ceramics are dry...
Silicon Carbide Reaction Sintering Process
SiC mainly has two crystal forms, namely high-temperature stable hexagonal α-SiC and low-temperature stable cubic β-SiC. The density of α-SiC is 3.217g/cm^3, and the density of β-SiC is 3.215g/cm^3. β-SiC has good stability at 2100 ℃, and it begins to transform into α-SiC above 2100 ℃, especially...
Aluminum alloy and stainless steel vacuum brazing
With the acceleration of the energy saving and environmental protection process and the lightweight trend of various mechanical parts in the automotive and industrial fields, the development and research of aluminum alloy and stainless steel vacuum brazing technology is becoming more and more imp...
Vacuum sintered powder metallurgy parts
Powder metallurgy is an important part forming technology. The continuous emergence of new technologies and processes of powder metallurgy will surely promote the rapid development of high-tech industries, and will also bring bright prospects for material engineering and manufacturing technology....
316L stainless steel vacuum brazing process
316L stainless steel has good corrosion resistance, oxidation resistance and high temperature mechanical properties and is widely used. The corrosion resistance and high temperature performance of nickel-based solder vacuum brazing joints are superior to other solders, especially suitable for vac...
Vacuum heat treatment of aluminum alloy die castings
The lightweight and green manufacturing of automobiles has created a demand for high-stability, high-strength aluminum alloy materials. Aiming at the problems of insufficient strength and stability of the existing aluminum alloy body components, the vacuum heat treatment process was optimized by ...
Selection Guide for Vacuum Sintering Furnaces
Vacuum sintering means that powder, powder compact or other forms of materials are heated at an appropriate temperature in a vacuum environment, and the connection between particles is achieved by means of atomic migration. The purpose of sintering is to make the porous powder compact an alloy wi...
Vacuum Oil Quenching for steel hardening heat treatment
Oil quenching is proposed for small parts with relatively large workpieces, quenching temperatures below 1000°C, and relatively high hardenability. The requirements for vacuum quenching oil are as follows: (1) Low vapor pressure, not easy to volatilize. The vapor pressure is required to be lower ...
MIM degreasing and sintering for ceramic hard alloy
The material systems of the currently used MIM degreasing and sintering furnaces mainly include: Stainless steel, iron-based alloys, magnetic materials, tungsten alloys, hard alloys, fine ceramics and other series. Cemented carbide, known as “industrial teeth”, is widely used in vario...
