ABSTRACT:
The present invention relates to a modular, rotisserie type coating fixture for use in electronic beam physical vapor deposition (EB-PVD) coating processes. The fixture includes a support structure which rotates about a first axis during coating and a plurality of cassettes mounted within the support structure. The cassettes each hold a plurality of workpieces to be coated and are mounted in the support structure so that they rotate about axes parallel to the first axis. This allows each workpiece being coated to rotate about its longitudinal axis and to achieve an evenly distributed, substantially uniform coating on surfaces of the workpiece to be coated.
