High Quality Industrial Vacuum Furnace High temperature sintering vacuum furnace China wholesale

Product description

Vacuum sintering is a process in which powders, powder billets or other forms of materials are heated under vacuum at the appropriate

heat at the appropriate temperature to achieve interparticle linkage by means of atomic migration. The purpose of sintering is to make porous

The purpose of sintering is to give a porous powder billet a certain structure and properties of an alloy.

Application of vacuum sintering furnace:

Vacuum sintering furnace is mainly used for powder metallurgy products, metal injection molding products, stainless steel-based

Cemented carbide, super alloy, high specific gravity alloy, ceramic material, magnetic material, NdFeB, etc.

Advantages of vacuum sintering:

1. Vacuum sintering can reduce the harmful components in the atmosphere (water, oxygen, nitrogen and other impurities, etc.). Contamination of the material, avoiding a series of reactions such as decarburization, carburization, reduction, oxidation and nitriding. The vacuum environment is not available in other forms of sintering (when the vacuum in the furnace reaches 1.3*10 Pascal, the remaining gas in the furnace is equivalent to 99.99987% argon gas purity);

2. Vacuum sintering enables the material to be completely excluded from the particle oxide film before the liquid phase appears, thus improving the wettability of the liquid identical carbide phase, improving the alloy structure and improving the alloy properties;

3. Due to the reduced amount of gas in the pores of the pressed billet under vacuum, it is easier for the gas products to be discharged from the pores as well as the removal of gas dissolved in the metal.

4. vacuum sintering can make the material more wear-resistant and stronger;

5. Vacuum sintering also has a significant effect on reducing the cost of the product:
