Pratt & Whitney has launched ultrasonically pulsed waterjet stripping method PurePulse, a technology to remove hard coatings/materials applied by thermal spraying and plating processes, using 30% of the pressure of traditional units. The method was procured from Ottawa-based VLN Advanced Technologies, and has received its first purchase order, from an unnamed land based turbine engine company.
VP-business development and aftermarket services Bill Begert told, “It uses the pulse of the water that’s precisely tuned to whatever part you’re trying to strip, of chrome or some other type of material, and it does it at a much lower PSI than traditional water stripping machines do. As a result, it improves the producability of stripping it 5 times, 10 times, 15 times depending on the size and the kind of part that you have. It’s able to do this without harming the substraight beneath the chrome or the other material.”
Begert said the PurePulse method may be extended beyond engine technology to landing gear and other aviation parts.
