Aviation vacuum brazing process
Brazing, as the earliest material connection method used by humans, has a long history of application in the aviation field. In recent years, with the increase in technical challenges in the fields of aviation manufacturing and aviation maintenance, this technology has also kept pace with the tim...
Vacuum heat treatment is critical for automotive and aerospace component manufacturers
Vacuum heat treatment is critical to automotive and aerospace component manufacturers, as the industry demands the highest levels of quality. Brazing and surface treatment are two process areas that utilize vacuum technology. Vacuum Brazing More parts are produced using vacuum brazing than any ot...
Selecting the right vacuum heat treatment process for powder metallurgy
Powder metallurgy is a process that uses metal powders (or mixtures of metal and non-metal powders) of micron to nanometer scale as raw materials, and combines these particles tightly through molding and vacuum sintering to prepare various engineering materials and parts with complex shapes. In t...
Industrial heat treatment equipment – vacuum furnace
In modern industrial production, the progress of materials science has promoted the development of many fields. Among them, vacuum furnaces, as an important technical means, play an indispensable role in metal processing, semiconductor manufacturing, aerospace and other fields. Vacuum Furnace Pro...
Alloy metal honeycomb vacuum brazing
FeCrAl alloy is an important electric heating material, usually used for electric heating elements. As one of the most widely used metal electric heating materials, FeCrAl electric heating alloy contains a large amount of Cr and Al. Under high temperature conditions, a dense oxide film will form ...
How to use vacuum heat treatment furnace for annealing
The annealing process system is determined according to the requirements of alloy properties, work hardening degree and product technical conditions. The main process parameters of annealing are annealing temperature, holding time, heating speed and cooling method. The determination of the anneal...
Vacuum Furnace Preventive Maintenance Strategies
Daily maintenance of vacuum furnace: (1) Operators should be familiar with various instruments, pumps, and various parts of the equipment. Read and understand various manuals. (2) The cooling water pressure should be maintained between 0.1 and 0.2 MPa, and the outlet water temperature should be ≤...
Optimization measures for vacuum brazing of aluminum alloy water-cooled radiator
Aluminum alloy water-cooled radiators are increasingly widely used in heat dissipation fields such as rail transportation, aerospace, ships, and wind power due to their high efficiency in heat dissipation, green and safe characteristics. Vacuum brazing does not require the addition of brazing flu...
Common defects of vacuum brazing and their solutions
Common defects of vacuum brazing 1. Dissolution Reason: The brazing material does not match the base material, forming a low melting point phase. The heating rate is too slow or the holding time is too long. The vacuum brazing temperature is too high or the local temperature is uneven. Solution: ...
Answering the question of material hardness after vacuum brazing
When vacuum brazing 4340 steel with PDC (polycrystalline diamond composite), it is a technical challenge to ensure that the hardness of 4340 material does not decrease. 4340 steel is a high-strength alloy steel, and its hardness depends on vacuum quenching and vacuum tempering heat treatment. The...
