ABSTRACT:
Field emission spraying of liquified metals is obtained using an electrically heated face plate in contact with the metal to be sprayed with nozzles formed in the face plate. The face plate is wettable by, but insoluble in, the metal to be sprayed and is maintained at a temperature in excess of the melting point of the metal to be sprayed by passing an electric current therethrough.
