More Information
Summary:Disclosed are a plasma nano-powder synthesizing and coating device and method, the device comprising: a chamber which forms a sealed space, and comprises a reaction unit provided at one side and a processing unit provided at the other side, the reaction unit provided in an upstream of gas flowing in the chamber, having a high-temperature plasma region formed by a plasma torch generating plasma with an applied electric current, and comprising a mixed gas feeder to supply mixed gas to the reaction unit and a powder feeder to supply powder to the reaction unit, and the processing unit provided in a downstream of plasma flame in the chamber, and comprising a supporter to support a material; and a vacuum forming unit which forms a vacuum inside the chamber, the powder being supplied to the reaction unit and reacting in the plasma region of the reaction unit, and the reacted powder being synthesized in the reaction unit, the processing unit and a surface of the supporter, and coated on a surface of the material of the supporter to form a coating layer. With this, reaction, synthesis and coating of heterogeneous powder are simultaneously performed, and various reaction conditions can be simply and conveniently controlled.
