Spray coating processing SPRAY PROCESSING
Plasma-sprayed alumina insulating coating for torch (welding gun) components
Characteristics of Plasma Spraying: (1) It can spray a wide variety of coating materials, especially those with high melting points and refractory materials such as refractory metals, ceramics, metal-ceramics, and other special functional materials. (2) Inert gases can be selected as the working medium, reducing oxidative reactions of sprayed particles during flight. (3) The coating exhibits high bonding strength and low porosity; fine coatings can be prepared by precisely controlling process parameters.
Product Description
Plasma-sprayed alumina insulating coating for torch (welding gun) components
Introduction to Plasma Spraying Technology
Plasma spraying is a thermal spraying process that uses a plasma arc as the heat source and primarily employs spray powder materials.
Steps of Plasma Spraying
During plasma spraying, a direct-current arc is generated between the cathode and the anode (nozzle). This arc heats and ionizes the introduced working gas, transforming it into a high-temperature plasma that is ejected from the nozzle, forming a plasma jet. Powder particles are fed into the plasma jet by a powder-feeding gas, where they are melted, accelerated, and sprayed onto the substrate material to form a coating. The working gas can be argon, nitrogen, or a mixture of these gases with hydrogen added; alternatively, a mixed gas of argon and helium can also be used.
Characteristics of Plasma Spraying
(1) Capable of spraying a variety of coating materials, especially high-melting-point and refractory materials such as refractory metals, ceramics, metal-ceramics, and other special functional materials;
(2) Inert gases can be selected as the working medium to reduce oxidative reactions of spray particles during their flight.
(3) The coating exhibits high bonding strength and low porosity; fine coatings can be prepared by controlling process parameters.
