Metallic cathode surface modification by using low pressure pulsed vacuum arc discharge
Electrical discharges in a pulsed vacuum arc system at low pressure were produced using a peak current of 100A with pulses of 30 ms. Discharges were carried out applying a voltage of 104 V between the electrodes. Materials used as cathode were Ti, Zr, Ni, Cu, Mo and W. The cathodes morphology after...
