Making powder is the primary operation of powder metallurgy. Powder metallurgy materials and products continue to increase and their quality continues to improve. The more types of powders required, the better. For example, in terms of material, not only metal powders, but also alloy powders are used. Metal compound powder and so on. From the perspective of powder shape, powders of various shapes are required. For example, when a filter is produced, it is required to form powder; from the perspective of powder particle size, powders of various particle sizes are required. The coarse powder has a particle size of 500-1000 microns, and ultrafine The particle size of the powder is less than 0.5 microns and so on.

The method of turning metals and alloys or metal compounds into powder in a solid state:

There are mechanical pulverization and galvanic corrosion methods for preparing metal and alloy powders from solid metals and alloys, and reduction methods for preparing metal and alloy powders from solid metal oxides and salts. From metal alloy powders, metal oxides and non-metal powders Reduction method for preparing metal compound powder.

The method of turning metal and alloy or metal compound into powder in liquid state:

1. There are substitution method and solution hydrogen reduction method for preparing metal alloy and coating powder from metal salt solution substitution and reduction.

2. Atomization method for preparing alloy powders from liquid metals and alloys, molten salt aging method for preparing metal powders by precipitation from molten metal salts, and metal baths for preparing metal compound powders by precipitation from auxiliary metal baths Law.

3. There is an aqueous solution electrolysis method for preparing metal and alloy powders from metal salt solution electrolysis, and a molten salt electrolysis method for preparing metal and metal compound powders from molten metal salt electrolysis.

The above is about the preparation methods of powder metallurgy. I hope it will be helpful to everyone. If you have other questions or need to process powder metallurgy, please feel free to call for consultation. We look forward to your call!
