ABSTRACT:
One shot coating of powdered material with a metal film is achieved by allowing the material to fall through a vertical refractory cylinder, the inside of which is covered with the metal. The process takes place in a vacuum chamber and the cylinder is heated to evaporate the metal onto the falling material as it passes through the cylinder.
