A coating apparatus includes a cylindrical holding chamber having open
ends, an opening formed in an inner surface and an inner diameter; a
specimen having a curved inner surface with a radius of curvature that is
equal to one half the inner diameter of the cylindrical holding chamber,
the specimen having a size such that, when inserted in the opening in the
inner surface of the cylindrical holding chamber, the inner surface of
the cylindrical holding chamber and the curved inner surface of the
specimen form a continuous surface; a counter bore formed radially
outward from the opening in the inner wall of the cylindrical holding
chamber; at least one evacuation hole extending from an interior of the
cylindrical holding chamber through a wall of the cylindrical holding
chamber to the counter bore; a flat formed on an exterior surface of the
cylindrical holding chamber around the counter bore; and fastener holes
formed around the counter bore and extending from the flat into the wall
of the cylindrical holding chamber.
