Abstract
ABSTRACT: Temperature control has been a major concern during High Velocity Oxygen Fuel (HVOF) processing since its introduction to the aerospace industry. Typically, substrate temperature must not exceed 300oF to prevent heat damage/ tempering of steel alloys, and even lower temperature requirements for aluminum and titanium alloys. Shop air cooling, most common temperature control, has proven to be inadequate for controlling substrate temperatures during many HVOF applications. As a result, longer off-part dwell times are required to allow for component cooling that results in significant cost due to powder and gas consumptions. Traditionally temperature measuring control has been a continuous single infrared point location on the component being sprayed. Consequently, temperature variations across the component causes inaccuracies. Phase I and II of this effort matured the ES3 novel cooling and temperature monitoring system on 6Al-4V Ti substrate to a TRL 7 by evaluating the system"s affect on fatigue and coating integrity characteristics; including Demostration/Validation testing on a C-5 slat track proving its overall effectiveness for future implementation. Phase II.5 will focus on additional qualification testing on 4340 steel and Inc718 substrates, and develop a technical data package for engineering evaluation for implementation, maturing the overall process to a TRL 8. BENEFIT: ES3 anticipates the results of Phase II.5 work will qualify and validate the usage of the ES3 novel cooling and temperature monitoring system for typical alloys utilized on aircraft components qualified for HVOF coating application. ES3 anticipates the following benefits from Phase II testing: A novel cooling process for HVOF coating applications Specifications for a Multi-location Temperature Monitoring System Eliminate extended off-part dwell time for cooling Reduce process time Reduce powder and fuel costs Environmentally friendly process
