ABSTRACT:
This invention includes a method featuring steps having a transport (64, 68) to carry metal articles (10, 14) through a vacuum chamber (62, 66, 90) containing a plasma cleaning station (32) followed by exposure to an evaporant of metal (42) generated by an E-Beam (50) caused to condense on the articles in high vacuum. A channel structure (51) is provided to cause selective condensation upon the surface of said articles. The apparatus includes several stations (101, 102, 103) to provide multiple coatings on one or both sides of an article to be coated.
