ABSTRACT:
Plasma spray coating of parts in a low-pressure chamber utilizes a linear induction motor drive system having gapped tracks for supporting and driving part carriers to flow in a continuous series of discrete steps through the low-pressure chamber where the parts are momentarily stopped for preheating and spray coating. Input and output air locks are sealed and unsealed by valve gates that move through the track gaps to optimize the sealing of the locks.
