Abstract
In vacuum plasma spraying a turntable must be provided which not only makes it possible to rotate and tilt a heavy workpiece, but to operate at vacuum plasma temperatures to do so. In the vacuum plasma coating of large parts such as combustion chambers of rocket engines the workpiece must not only be rotated, but it must be tilted. Hence the turntable must be capable not only of supporting heavy parts, but of angulating such heavy workpieces. And this must be done without drive means failure due to extremely high temperatures under which the turntable mechanism is operated. Herein a turntable mechanism is provided which is capable of operating under such conditions. For cooling the turntable drive mechanism internal cooling means are included.
