Experimental measurement of the powder flow velocity in a three-port coaxial laser metal deposition nozzle by high-speed imaging

Abstract: Additive manufacturing has been successfully used as a new technology to produce complex components with improved properties compared with the traditional manufacturing process. However, the powder used as feedstock requires a homogeneous powder mass flow. Velocity and amount of powders fed into the molten pool are crucial to obtain reproducible deposits (tracks). Therefore, monitoring of key parameters in the laser metal deposition (LMD) process is of high importance to obtain repeatability during either repa… Show more
