摘要：
Zirconium cathodes with a nitrided surface layer are promising candidates for arc-heater tests in air because of their good erosion resistance and excellent physical properties Nitriding of a zirconium cathode is performed by a microwave plasma generator Nitrided cathode, yield a stable plasma flow of argon air up to 80 A at a maximum flow rate of 4 l/min argon and 08 l/min air for a long duration The specific input power corresponds to 11 8 MJ/kg During arc-heater testing nitriding is a governing reaction and golden zirconium nitride is formed at the tip of the cathode surface The formation mechanism of a ceramic layer during microwave plasma generator treatment and arc-heater testing will also be discussed (C) 2010 Elsevier Ltd All rights reserved
