ABSTRACT:
An improved plastic camera housing having an exterior decorative metallic coating and method of producing the same is disclosed. The camera housing assembly can comprise a polycarbonate glass fiber filled molded part that has been plasma etched in an inert argon gas filled pressure vessel. The camera part is plasma etched for a brief period of time to deteriorate the cross linkage of plastic bonding of the surface polymers without causing any outgassing of the elements of the plastic. A layer of copper is deposited to an approximate thickness of 1 to 3 microns in the inert subatmospheric environment. A second exterior layer of chromium approximately 0.2 to 0.5 microns is subsequently deposited to provide a hard abrasion resistant surface. Alternatively, a lacquer subsurface layer can be sprayed onto the camera part before the initial plasma etching.
