| Abstract: | Direct current plasma spray torch is the core component in the plasma spraying system, which
determines the melting softening deposition effect of particles and the coating performance. The influence of
the structural characteristics of key components such as cathode, anode ( nozzle ) and gas distribution ring on
plasma jet was summarizes. The structural optimization and development of DC plasma spray torch were further
introduced, focusing on the stability of plasma jet and the improvement of coating deposition efficiency. The
optimization of jet stability by cascade plasma spray torch and the improvement of coating deposition efficiency
by powder feeding method were introduced. The future development trend was prospected. |
