ABSTRACT:
An improved electrode contact system for metal vaporization electrodes or rods which are electrically and supportively connected to a movable carriage which also receives and supports objects such as parts and components in a vacuum chamber during metal vapor deposition. A metal such as aluminum, chromium, or nickel-chromium, etc. is vaporized centrally in the chamber by contact with electrically energized electrodes or elongated rods in a well known fashion after the chamber has been substantially evacuated of air molecules for uniform vapor deposition of the vaporized metal atop exposed surfaces of the objects. The electrode contact system provides an automatic, self-aligning plug-in assembly for each electrode rod so that, as the carriage, loaded with parts and components to be metal vapor coated is rolled into position within the vacuum chamber, each two-part contact system automatically fully engages. Vibration from carriage rotation during cleaning and vapor deposition and monomer coating will not materially affect current or voltage levels being transferred to each electrode thereby.
