Metal powder manufacturing method: divided into physical method and chemical method.
Physical methods include mechanical ball milling, water atomization, gas atomization, etc.
Chemical methods include electrolysis and carbonyl method.
Here is a brief introduction to the most commonly used physical method of mechanical ball milling:
1. Put the metal block into the melting furnace and heat it to melt.
2. After the metal melt flows through the screen or turns the disc, it falls into the liquid cooling medium and condenses into small socks.
3. Add small particles of metal together with protective gas into the sealed vortex pulverizer for pulverization by extrusion and friction between metal particles.
Disadvantages: Mechanical crushing is difficult and will bring in impurities.
