High precision disc rolling scissors vacuum heat treatment
High-precision disc rolling scissors (hereinafter referred to as rolling scissors), the material is Cr12MoV, and the parallelism and thickness tolerance of the finished product are within 0.005mm. In recent years, with the rapid development of the market economy, the supply period is further shor...
Thrust Chamber Head Titanium Brazing News
The thrust chamber head of the liquid rocket engine requires light weight, compact structure, high strength, good heat resistance and reliable operation. Therefore, most of the small and medium thrust engines working in space use the structural design of the titanium alloy straight-through inject...
Small diamond saw blade vacuum sintering
At present, the production process of small diamond saw blades is roughly as follows: batching – mixing – feeding – cold pressing – sintering. Among them, in the sintering process, pit-type batch furnaces and reducing atmosphere furnaces are mainly used to process the sint...
Vacuum Sintering of Metal Matrix Composites
Metal matrix composites have attracted the attention of scholars and researchers from all over the world due to their high specific strength, specific stiffness, good thermal stability, wear resistance, dimensional stability and composition design. hot spot. At present, steel matrix composites ar...
316L stainless steel vacuum sintering
Powder metallurgy sintered austenitic (SS-300 series) stainless steel is widely used in industry, among which sintered 316L has excellent corrosion resistance. Austenitic stainless steel does not undergo phase transformation after heat treatment, and cannot be hardened by heat treatment. In the c...
Vacuum brazing of honeycomb sealing structure
The power turbine part of the FT8 gas turbine adopts a large number of honeycomb sealing structures. The brazing technology of honeycomb structure is a difficult new technology. Setting, control of brazing material, brazing process and equipment, inspection of brazing quality, etc. 1. Solder sta...
Knife and scissors vacuum heat treatment
In the international market, the cutting tool manufacturing industry in Japan and West Germany is very developed, and the technology and quality are in a leading position in the world, especially in terms of raw materials, which are superior to my country’s knife and scissors industry. Ther...
Vacuum heat treatment of stop spring
The stop spring is one of the important parts in the compensator body of the governor. During the working process, the position of the adjusting screw sleeve is fixed by the stop spring, so as to adjust the oil volume of the engine at medium and low speed. Since the thickness of the part is only ...
Vacuum brazing heat treatment technology of joystick assembly
Vacuum brazing is a kind of advanced welding in which the workpiece is in a vacuum state, that is, in a negative pressure atmosphere, using a heat source to heat the solder into a liquid, and relying on the action of the capillary to fill the gap between the solid parts and form a metallurgical c...
Disc mold vacuum brazing
Discs used in DVD players are thermoformed using molds. In order to ensure the quality of the disc, high technical requirements are placed on the mold. The surface hardness of the mold after quenching is greater than HRC58, and the long-term stability of the mold size must also be maintained. Dur...
