Pressure-Controlled Atomization Process (PCAP) for Dimensional Restoration of Aviation Parts. Part 1

摘要

The Pressure-Controlled Atomization Process (PCAP) is a new thermal spray process in which a liquid metal is atomized in a supersonic nozzle, which also directs the spray to a suitable substrate. The Spray Casting Project was jointly sponsored by the United States Air Force, Armstrong Laboratory Environics Directorate at Tyndall AFB, and the United States Department of Energy, Office of Technology Development (DOE-OTD) under the U.S. Air Force-DOE Memorandum of Understanding (MOU). The Air Force application uses the Pressure Controlled Atomization Process (PCAP) to thermally spray metallic replacement coatings for electroplated hard chromium. The report presents a history of PCAP as it relates to the development of the process, the development of the hardware to support the process development and the testing that was conducted to understand the process and generate engineering data to support the replacement hard chromium electroplating with PCAP sprayed coatings.
