Abstract: An ultrasonic waterjet apparatus (10) has a mobile generator module (20) and a high-pressure water hose (40) for delivering high-pressure water from the mobile generator module (20) to a hand-held gun (50) with a trigger and an ultrasonic nozzle (60). An ultrasonic generator in the mobile generator module (20) transmits high-frequency electrical pulses to a piezoelectric or magnetostrictive transducer (62) which vibrates to modulate a high-pressure waterjet flowing through the nozzle (60). The waterjet exiting the ultrasonic nozzle (60) is pulsed into mini slugs of water, each of which imparts a waterhammer pressure on a target surface. The ultrasonic waterjet apparatus (10) may be used to cut and de-burr materials, to clean and de-coat surfaces, and to break rocks. The ultrasonic waterjet apparatus (10) performs these tasks with much greater efficiency than conventional continuous-flow waterjet systems because of the repetitive waterhammer effect A nozzle with multiple exit orifices or a rotating nozzle (76) may be provided in lieu of a nozzle with a single exit orifice to render cleaning and de-coating large surfaces more efficient. A water dump valve (27) and controlling solenoid are located in the mobile generator module (20) rather than the gun (50) to make the gun lighter and more ergonomic.

Abstract: 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 VTR of the nozzle, a water pressure P, a water flow rate Q, a length-to-diameter (L/d) ratio, a microtip-to-orifice distance (a), the frequency f, and an amplitude A of the high-frequency signal.

Abstract: An innovative method of prepping a surface entails entraining a coating particle into a fluid stream, directing the fluid stream containing the coating particle at the surface to be prepped to thereby prep the surface using the coating particle. The prepped surface can then be coated using the same or substantially similar coating particle. This method can be used with a continuous airjet, a forced pulsed airjet, a continuous waterjet or a forced pulsed waterjet as the carrier stream. This invention solves the problem of foreign blasting particles becoming embedded in the atomic matrix of the surface to be prepped, which can result in unpredictable behaviour of the surface properties and even catastrophic failure.
