Abstract

Plasma, generated by vacuum-arc discharge with titanium cathode at Ar and N₂ presence, has been investigated using a quadruple RF mass spectrometer and multigrid electrostatic probe. Metal and gas ions radial flows intensities and their energies depending on discharge current and gas pressure has been investigated. It is defined that gas ions created by interaction between primary erosion metal plasma flow and gas target motion mainly in the radial direction as a result of particles dispersion on the large angles, which is characteristic to recharging processes
