    Abstract: A method is described for reducing surface oxide growth which heating aluminum containing surfaces in a vacuum environment prior to the deposition of a ceramic coating. The method comprises flowing an inert or non reactive gas into the coating apparatus adjacent to the surface to be coated to reduce oxygen reaction with the surface.

    Abstract: The present invention relates to an apparatus for simultaneously coating a plurality of workpieces (54). The apparatus includes a module (10) fixture having a plurality of bushing (48) and spindle (64) arrangements for supporting the workpieces to be coated. The bushing and spindle arrangements allow each workpiece to rotate about its longitudinal axis (122) and tilt along an axis (14) which intersects the rotational axis of the fixture. By providing such a bushing and spindle arrangement, it is possible to coat surfaces of the workpiece which are substantially perpendicular to other surfaces of the workpiece. A process for simultaneously coating the workpieces is also described. The process comprises the steps of mounting a plurality of workpieces to the fixture so that the workpieces can roll about their longitudinal axes and so that the workpieces are positioned at an angle with respect to the rotational axis of the fixture, rotating the fixture about its rotational axis so as to cause said workpieces to roll, and exposing the workpieces to a coating material as the fixture is being rotated.

    Abstract: A modular fixture (14) for coating a plurality of workpieces comprises a first end plate (20) and a second end plate (22) spaced from said first end plate (20). A longitudinal axis (28) extends from the first end plate (20) to the second end plate (22). Means is provided for enabling said fixture to be rotated about a first axis (36) parallel to the longitudinal axis. A first arm (42) is attached to the first end plate (20) and first rotation means incorporated within the first arm (42) for allowing a first part to rotate about a second axis (56) at an angle relative to the first axis (36) and for allowing the first part to tilt relative to the first axis (36) while the first part is rotating about said second axis (56). A second arm (42) is attached to the second end plate (22) and second rotation means incorporated within the second arm (42) for allowing a second part to rotate about a third axis (56') at an angle relative to the first axis (36) and for allowing the second part to tilt relative to the first axis (36) while the second part is rotating about the third axis (56').
