摘要
The invention relates to a plasma transfer wire arc thermal spray system, comprising a section for feeding a wire (20) acting as a first electrode, a source of plasma gas providing plasma gas (16), a nozzle (10) directing the plasma gas stream (16) from the source of plasma gas to a free end (21) of the wire (20), and a second electrode (30) located in the plasma gas stream (16) towards the nozzle. The inventions is characterized in that the nozzle (10) is made at least partially of electrically insulating material. The thermal spray apparatus with the inventive spray gun is having a simplified and faster starting procedure and is the spray nozzle is more durable.
