POWDER FEEDING AND COATING APPARATUS WITH LOW PRESSURE SPRAY NOZZLE

摘要

PURPOSE: An apparatus for supplying metal powder using a low pressure nozzle with a coating process is provided to form a porous metal coating film with a uniform thickness by consecutively supplying the preset amount of the metal powder. CONSTITUTION: An apparatus for supplying metal powder using a low pressure nozzle with a coating process includes a high pressure generating unit(20), a powder supply tank(50), a metal powder discharging part(60), a second connection pipe(32), a third connection pipe(33), and an injection nozzle(80). The metal powder discharging part discharges the metal powder to the metal powder discharging part with pressure difference. The second connection pipe includes the metal powder discharging part. The second connection pipe includes a heating unit(70).
