ABSTRACT:
A molten metal spray-depositing apparatus employs an ejection nozzle for receiving a molten metal stream and having a configuration for confining and imparting mechanically an angular momentum thereto which produces stream break-up into a metal particle spray when the stream becomes unconfined upon exiting the nozzle. There are stationary and rotating versions of the ejection nozzle. The stationary ejection nozzle has a flow channel with internal angular elements, such as spiral grooves, which engage the moving molten metal stream to impart angular momentum thereto as it passes through the channel. The rotating ejection nozzle may have internal elements within the flow channel, such as notches or serrations, which engage the moving molten stream and cause it to rotate with the nozzle as it passes through the channel. The two nozzles can also be combined to impart the angular momentum and accomplish melt stream break-up.
