The Oerlikon Metco F4 atmospheric plasma spraying system is based on a conventional direct-voltage single-cathode plasma generator. The arc is lit using a pen-shaped cathode and an anode which is set up as a nozzle. The plasma gas that flows by is ionised and dissociated at the arc and thus transferred into the plasma state. The core zone of the recombination lies directly behind the nozzle exit, where the powder-formed spraying material is radially injected into the flow of plasma. In a general way, mixtures of argon, nitrogen and hydrogen are used as plasma gases. The typical output of the F4 torch is P = 40 – 55 kW.
