The behaviour of hafnium cathodes at the beginning of their service life when operating at high current levels in the plasma arc cutting (PAC) process has been experimentally investigated with the final aim of understanding the phenomena that take place during those initial piercing and cutting phases and optimizing the initial shape of the surface of the emissive insert exposed to plasma atmosphere.

Abstract
The behaviour of hafnium cathodes at the beginning of their service life when operating at high current levels in the plasma arc cutting (PAC) process has been experimentally investigated with the final aim of understanding the phenomena that take place during those initial piercing and cutting phases and optimizing the initial shape of the surface of the emissive insert exposed to plasma atmosphere.File in questo prodotto:
