MengziPlasma Ceramic Coating—Alumina, Titanium Dioxide, Zirconia, and Chromium Oxide Ceramic Plasma Spraying Equipment

Introduction to Plasma Spraying Technology Plasma spraying is a thermal spraying method that uses a plasma arc as the heat source and relies primarily on 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 flame. The powder material is fed into the flame by a carrier gas, where it is 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.

SX-80 Plasma Spraying Equipment

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 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.

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.

SX-80 Plasma Coating Equipment

It was successfully developed based on the introduction and absorption of plasma spraying equipment such as the PT-A3000 and METCO-9M, and its overall equipment level is comparable to that of the METCO-9M. The equipment consists of the following systems: ① main power supply; ② control cabinet; ③ junction box; ④ powder feeder; ⑤ spray gun; ⑥ heat exchanger and piping connections. The equipment’s key components and instruments all utilize products from well-known brands such as Schneider, Omron, and Chint, ensuring the equipment’s stability and efficiency.

Equipment design operating environment:

Voltage: AC 380V ±10% Frequency: 50 Hz Temperature: -5 to 40℃ Relative humidity: 50-95%
