| 20100015892 | METHOD AND APPARATUS FOR PREPPING SURFACES WITH A HIGH-FREQUENCY FORCED PULSED WATERJET - A method of prepping a surface using a high-frequency forced pulsed waterjet entails generating a high-frequency signal having a frequency f using a high-frequency signal generator, applying the high-frequency signal to a transducer having a microtip to cause the microtip of the transducer to vibrate to thereby generate a forced pulsed waterjet through an exit orifice of a nozzle having an exit orifice diameter d and a length L. The forced pulsed waterjet prepares the surface to within a predetermined range of surface roughness. The surface roughness is determined by selecting operating parameters comprising a standoff distance (SD), a traverse velocity V | 01-21-2010 |
