ABSTRACT:
As intermetallic composite, bar evaporation source constructed from a mixture of borides and nitrides for use in the evaporation of metals, e.g., aluminum, is arc sprayed with a layer of the metal to be subsequently evaporated therefrom before use. The coated layer of the metal to be evaporated increases the wettability of the bar source cavity and creates greater electrical stability when compared with similar but uncoated bars.
