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).

Claims (13)

1. A method of applying a tamper resistant coating comprising:

placing a plurality of parts to be coated into a device-holding fixture;

positioning the device-holding fixture into a primer pallet designed to accommodate a plurality of device-holding fixtures;

applying a primer coating to the primer pallet;

removing the device-holding fixture from the primer pallet;

fixing the device-holding fixture to a thermal spray target wheel having a plurality of radial arms and spaces therebetween, each of the plurality of radial arms having a distal end, the plurality of radial arms being connected to each other at their respective distal ends;

applying a thermal spray coating; and

removing the device-holding fixture from the wheel.

2. The method of claim 1 wherein placing the one or more parts to be coated into the device-holding fixture comprises:

inserting the one or more parts to be coated into a handling strip; and

placing the handling strip between a mask plate and a receptacle plate of the device-holding fixture.

3. The method of claim 1 , further comprising cleaning a mask portion of the device-holding fixture before applying the thermal spray coating.
