Description

Technical Field

[0001] This utility model relates to the technical field of plasma spraying equipment, specifically a controlled atmosphere plasma spraying equipment. Background Technology

[0002] Atmospheric plasma spraying, or simply plasma spraying, is achieved through a plasma spray gun. The nozzle (anode) and electrode (cathode) of the spray gun are connected to the positive and negative terminals of a power supply, respectively. A working gas is introduced between the nozzle and the electrode, and an electric arc is ignited by a high-frequency spark. The electric arc heats and ionizes the gas, generating a plasma arc. The thermal expansion of the gas propels a high-speed plasma jet out of the nozzle. A powder feed gas delivers powder from inside the nozzle (internal powder feed) or outside (external powder feed) into the plasma jet, where it is heated to a molten or semi-molten state and accelerated by the plasma jet, spraying it at a certain speed onto the pre-treated substrate surface to form a coating. Commonly used plasma gases include argon, hydrogen, helium, nitrogen, or mixtures thereof. With the widespread application of plasma spraying technology, some parts require coatings on the surfaces of small internal holes, placing specific requirements on the plasma spray gun, such as the inner hole diameter, length, and power of the spray gun, to meet the coating requirements of specific sprayed objects.
