Vacuum brazing of high temperature ceramic and metal joints
1. Vacuum brazing of structural ceramics Structural ceramics (such as Si₃N₄, SiC, Al₂O₃) have been widely used in mechanical processing, chemical industry, electronics, aerospace and other fields due to their excellent high temperature resistance, corrosion resistance and wear resistance. The rel...
Relationship between material surface roughness and vacuum brazing
Surface roughness is one of the important factors affecting the quality of vacuum brazing, especially in terms of the flow and wetting behavior of the brazing material and the performance of the joint. Vacuum brazing is a brazing process performed in a vacuum environment and is widely used to con...
Tips on controlling and influencing vacuum degree in vacuum brazing
Vacuum brazing is a brazing process performed in a vacuum environment. It is widely used in aviation, aerospace, nuclear energy and electronics, and is particularly outstanding in high-precision and high-demand applications. The core is to provide a low-pressure environment to avoid oxidation and...
Vacuum furnace manufacturers tell you the common methods of cleaning vacuum brazing furnaces
Oven Dry Run Cycle: This is a standard practice that involves heating the furnace without a load to burn off contaminants. According to the vacuum furnace maintenance procedure, it is recommended to heat the furnace to at least 1200°C (2200°F) and hold it for 30-60 minutes. However, for vacuum br...
Vacuum brazing technology of aluminum cold plate
Vacuum brazing technology Vacuum brazing is a high-precision process for joining metal parts in a vacuum environment by heating and using a brazing material with a lower melting point than the base material. It is widely used in the manufacture of aluminum cold plates. The heating stage is a key ...
Improvement of Vacuum Brazing Technology for Titanium Alloy Plate-Fin Heat Exchanger
A specific process improvement example for multi-layer vacuum brazing of 70-layer titanium alloy (Ti-6Al-4V) plate-fin heat exchangers. The 70-layer structure significantly increases the difficulty of heat transfer, brazing seam consistency requirements and deformation control challenges, so more...
Professional vacuum furnace manufacturer show you how to optimize titanium alloy vacuum brazing
Titanium alloys are widely used in aerospace, medical equipment and chemical industries due to their high strength, low density and excellent corrosion resistance. However, the high chemical activity of titanium alloys makes it easy to react with oxygen, nitrogen and other gases at high temperatu...
Vacuum furnace manufacturer analyzes the reasons for insufficient vacuum brazing rate of automobile aluminum oil cooler
The stacked vacuum brazing oil cooler is a safety part on the car, and the reliability requirements are high. The burst pressure is required to be greater than 4MPa, the pressure is alternating for 500,000 times, and the weld brazing rate is >60%. The air tightness and overall strength of the ...
Vacuum furnace manufacturers tell you a summary of vacuum furnace heating lag time
Summary of the research on the heating lag time of vacuum furnace: I. Main factors affecting the heating lag time a. Heating temperature Principle: When the heating temperature increases, the thermal radiation efficiency of the component increases to the fourth power (radiation energy ∝T⁴), the h...
How much do you know about silicon carbide ceramic sintering technology?
Silicon carbide (SiC) ceramic materials have broad application prospects in traditional industrial fields such as high-temperature kiln tools, combustion nozzles, heat exchangers, sealing rings, sliding bearings, and high-tech fields such as semiconductors and space technology due to their excell...
