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...
Study on Vacuum Brazing Technology of Silver-Cu-Based Solder
Vacuum brazing technology is one of the important processes in engine production. It is mainly used for the processing of stator rings, cold air passages of air-cooled blades, fuel main pipes and conduits, and metal honeycomb sealing structures. The welding of fuel pipes, oil inlet pipes, and ven...
Vacuum carburizing of aviation gear steel
At present, the accessory systems of aviation turbojet and turbofan engines all adopt gear transmission. With the increase of thrust and thrust-to-weight ratio of aero-engines, it is required that aero-engine gears must be able to withstand the comprehensive effects of various complex stresses, s...
Vacuum Brazing of Stainless Steel Plate-fin Radiator
Brazing is to use a filler material with a lower melting point than the base metal as the solder, heat the weldment and the solder to a temperature higher than the melting point of the solder and lower than the melting point of the base metal, and fill the gap between the base metals by melting t...
Vacuum brazing process of aluminum automobile radiator
The radiator has experienced three generations of development, namely copper radiator, aluminum assembled radiator and aluminum vacuum brazed radiator. So far, aluminum vacuum brazing radiators have become the trend of the times, and aluminum vacuum brazing is the most important way to manufactur...
Vacuum carburizing process for gearbox shafts and gears
Features of vacuum heat treatment Compared with the traditional controllable atmosphere carburizing heat treatment, the vacuum heat treatment technology has the technical characteristics of “green, environmental protection, energy saving and high efficiency”. The technology of automob...
