Spray coating apparatus and fixtures

Abstract

A system for applying a sprayed coating includes a spray mechanism operative to spray a liquefied coating material; a target system including a rotatable spray target wheel; and one or more device-holding fixtures configured to be mounted onto the spray target wheel without requiring either an unattached threaded fastener or a locking pin. Preferred embodiments of the system are configured for thermal spray application of Tamper Resistant Coatings (TRCs).

1 . A target wheel for a spray coating apparatus the target wheel comprising: 
 a wheel portion having a plurality of radial arms and spaces therebetween; and    one or more clamping assemblies attached to the wheel portion, the one or more clamping assemblies operative to clamp a provided device-holding fixture to the wheel portion;    wherein the wheel portion includes a circumferential surface at an outer periphery of the plurality of radial arms, the circumferential surface configured for monitoring surface temperature of parts subject to spray coating.
