Abstract: A method of pulsed laser processing of solid surface for enhancing surface hydrophobicity is disclosed wherein the solid surface is covered with a transparent medium during laser processing and the laser beam incidents through the covering medium and irradiates the solid surface. Two effects are obtained simultaneously. One is the laser-induced texture formation directly under the laser irradiation. The other is the deposition of the laser-removed materials along the laser scan lines. Both effects introduce surface roughness on nanometer scales, and both enhance surface hydrophobicity, rendering superhydrophobicity on the surfaces of both the laser-irradiated solid and the covering medium. Because the beam scan line spacing can be larger than a single scan line width by multiple times, this method provides a high processing speed of square inch per minute and enables large area processing.

Abstract: Metallic workpieces of diverse shapes having work surfaces which are deformed at the surface and adjacent sub-surface layers by surface impact from ultrasonic transducers employing freely axially moving impacting elements propelled and energized by a transducer oscillating surface vibrating periodically at an ultrasonic frequency. The impacting elements are propelled in a random aperiodic and controlled impact mode at different phases of the periodic oscillation cycles. The transducer may be portable and provides a series of mechanically interconnected stages having mechanical resonances harmonically related as a multiple of the primary ultrasonic frequency and have matched stage resistances under instantaneous loading when the impact elements are driven by the transducer oscillating surface into the surface of the workpiece. This mode of operation produces Q-factor amplification of the input ultrasonic power oscillator energy at the impact needles and high propulsion velocities making it possible to machine metallic workpiece bodies to greater depths for compressing the metal to increase compressive strength of the workpiece work surfaces to substantially the ultimate material strength. The impact machining is done at ambient temperatures.

Abstract: This invention provides methods of treatment for work products of materials such as steel, bronze, plastic, etc. and particularly welded steel bodies by pulse impact energy, preferably ultrasonic, to relax fatigue and aging and extend expectant life. The treatment may occur (a) at original production, (b) during the active life period for maintenance or (c) after failure in a repair stage. The ultrasonic treatment improves the work product strength. In welded products residual stress patterns near the weld sites are relaxed and micro-stress defects such as voids and unusual grain boundaries are reduced. The basic method steps are non-destructive in nature, inducing interior pulse compression waves with ultrasonic transducers and accessory tools impacting an external product surface with enough impulse energy to heat and temporarily plasticize the metal interior and relax stresses. The nature of the work product interior structure being treated is determined by sensing the mechanical movement at the impact surface of the work body to produce feedback frequency and phase signals responsive to input impact signals. These signals automatically conform driving pulse energy frequency and phase to the input transducers to match the mechanical resonance frequency of the working transducers and increase efficiency of energy transfer. Such feedback signals also are available for automated procedures which can improve product quality and consistency.
