Two engineering tests series were conducted to qualify the Pressure Controlled Atomization Process (PCAP) for use as a replacement for hard chromium electroplating as a means of refurbishing US Air Force aviation parts. The test series, Boeing and Wright Laboratory Test Series, were conducted on PCAP-coated specimens that were sprayed by MSE, Inc., and then tested by Boeing and the Wright Laboratory. Tests conducted included fatigue, abrasion, corrosion, adhesion, internal stress, chemistry, metallurgy, hardness, and materials compatibility and workability. In addition to the two test series, modifications to the spray system have been implemented to make the PCAP repeatable and controllable by a single operator. Modifications included installation of a vacuum/pressure spray chamber, design and installation of a new high temperature 1,800 C (3,272 F) inert gas heating system, and an automated tundish pressure control system to regulate the spray process. As the PCAP process has been refined, potential research and development applications have also been identified. These applications are well-suited to the characteristic narrow spray plume, low thermal input, and high deposition efficiency of the PCAP. Potential applications include development of a self-locking threaded fastener, development of anew method for rapid manufacturing of printed circuit boards, and possibly spraying ceramics as near-net shape components.
