Abstract: In an apparatus for initial ion cleaning, vapor metal deposition and protective coating of objects by vacuum deposition, an improved high voltage high current feedthru fitting with improved anti-fouling arc-resistant characteristics. The apparatus includes a vacuum chamber for receiving the objects which are held on a movable rack or support. A metal such as aluminum is vaporized centrally in the chamber in a well known fashion after the chamber has been substantially evacuated of air molecules for uniform vapor deposition of the metal atop exposed surfaces of the objects. The improved feedthru fitting is connected through a wall of an elongated housing which is connected over an elongated opening formed through a chamber side wall. An elongated conductive preferably aluminum rod is disposed within the housing along the opening into the chamber interior generally coextensive with two apertured delivery tubes or members positioned within the housing.

Abstract: A sputter coating apparatus for depositing a thin uniform material coating onto exposed surfaces of objects. The apparatus includes a vacuum chamber having one or more sealably closable doors through which objects treated by sputter coating are loaded into and removed therefrom and a support positionable within the chamber for supporting the objects to be sputter coated. A vacuum source establishes a vacuum in the chamber when the door is closed and the objects are held by the support within the chamber. A sputtering target formed of a material to be sputter coated onto the objects is operably connected within the chamber and spaced apart from the objects. A process gas inlet is operably connected to introduce a process gas such as argon or nitrous oxide into said chamber after a vacuum is established.

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.

A metal such as aluminum is vaporized centrally in the chamber in a well known fashion after the chamber has been substantially evacuated of air molecules for uniform vapor deposition of the metal atop exposed surfaces of the objects. An improved polymerization gun includes an elongated housing having an arcuate or concaved surface which is connected to an external surface of the chamber over an elongated opening formed through a chamber side wall. The polymerization gun also includes an elongated conductive preferably aluminum rod disposed along the opening tangentially to the chamber surface and two apertured delivery tubes or members positioned within the housing. The conductive rod is electrically isolated from the housing and chamber and connected to a d.c. or a.c.
