A technique for presenting and fixturing small items that are coated by vapor deposition techniques. The objects are caused to be moved within the plasma stream to effect full coverage. The coating, if titanium nitride, is gold colored and is, for example, useful for coinage applications.

An apparatus for plasma coating objects, the system comprising a sealable reactor chamber, means for introducing at least one ionic plasma stream into the reactor, an object of storage means disposed within the reactor chamber situated to receive the ionic plasma stream, the improvement comprising the object storage means including four peripheral sides defining a substantially open frame, a plurality of spaced parallel longitudinal races bridging two opposed sides, the longitudinal races adapted to hold the objects and allow rotational and continuous reciprocating translational locomotion of the objects along the length of the races, the length of each longitudinal race being longer than the total length of the objects situated within the longitudinal race, the open frame pivotally mounted on a support disposed within the reactor, and the support adapted to repetitively tilt the open frame through a predetermined arc to effect object locomotion within the races.
