Pulsed Wire Discharge (PWD)

 

 

   When a pulsed high current is driven through a thin metallic wire, the Joule heating causes electrical energy deposition which can turn the whole wire into a plasma.  By cooling this plasma with an ambient gas, we can obtain a large number of very fine solid particles.  This method of nanosize powder production was originally developed by our institute and was named as gPulsed Wire Dischargeh (PWD).
