Information

At present, the preparation methods of metal powder can be divided into reduction method, electrolysis method, atomization method, etc., each method has its own characteristics.

Among them, the reduction method and the electrolysis method are mostly used in the powder metallurgy industry, and are more suitable for the production of elemental metal powders. If it is alloy powder, these two methods will not be very practical. The atomization method can be used for the production of alloy powder, and the atomization process technology can also control the shape of the powder, which gradually makes it the main powder production method.

According to the way of powder solution, the atomization method can be divided into two-stream atomization method, centrifugal atomization, ultrasonic atomization and so on. These atomization methods have their own characteristics and have been applied in industrial production. Among them, the water atomization method has the characteristics of simple production equipment, low energy consumption, and can be produced in large quantities. It has become the main industrial production method.

Water atomization method:

The production cost of the water atomization method is very cheap, but it will perform very well in the atomization effect. This is because the medium cost of the atomization method is low and it is relatively simple to obtain. At present, the atomization method is mainly used to produce steel powder, matrix powder for diamond tools, pre-alloy powder for oil-impregnated bearings, and so on.

Because the specific heat capacity of water is greater than that of gas, in the process of atomization, the broken metal droplets solidify too quickly and become irregular, which will affect the sphericity of the powder.

In addition, there will be some highly active metals or alloys on the market. After they come into contact with water, they will also undergo chemical reactions, which will increase the oxygen content in the powder.

The above is the introduction of the preparation method of the metal powder. Do you all understand it clearly? I hope that the editor’s sharing can help you and let you know more professional knowledge.
