Impact of grain configuration and doping modulation on the thermal electron emission properties and mechanical properties of hafnium cathode
As an indispensable cathode material for plasma torches, hafnium (Hf) materials frequently exhibit inadequate hot cathode emission current density and operational lifespan, severely restricting their use in applications. Governing principles of thermal emission characteristics of Hf cathodes are not...
