摘要：
Powder is coated with valve-metal by rotating it in a drum 15 so that it is presented to valve-metal vapor derived by evaporation of a source of valve-metal. In the case of coating with aluminum, the vapor may be produced by directing aluminum wire 10 on to a heater 11, and oxygen or air is admitted to control agglomerate formation. Aluminum and tantalum coating are both described using electron beam evaporators.
