2. Manufacture of metal powders
Metal powders are a raw material that can be used in many different ways to manufacture complex parts. There are a number of technologies for producing powders: gas atomization, plasma atomization, hydriding/dehydriding for titanium, rotating electrode, underwater atomization for steel .
Rotating-electrode technology is unusual in that it is not suitable for mass production, and is therefore rather costly: it uses bars of the metal to be melted as raw material, and these bars must be carefully prepared to enable them to be rotated at high speeds without excessive imbalance. The process cannot be continuous,...
