Spray coating processing SPRAY PROCESSING
Silicon carbide substrate coated with a zirconia-alumina composite coating for wear resistance and corrosion protection.
Introduction to the Configuration of the SX-80 Plasma Spraying Equipment The SX-80 plasma coating equipment was developed based on the introduction and absorption of plasma spraying equipment such as the PT-A3000 and METCO-9M. Its overall performance level is comparable to that of the METCO-9M. This equipment comprises the following systems: ① main power supply ② control cabinet ③ transfer box ④ powder feeder ⑤ gas-electricity safety center ⑥ spray gun ⑦ heat exchanger and piping connections, among others.

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.
① 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 into a high-temperature plasma, which is then ejected from the nozzle to form 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.
② 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.
③ Main equipment for plasma spraying
Including the spray gun, powder feeding mechanism, rectifier current, air supply system, water cooling system, and control system.
