Highlights The Proposed multi-microjet impact model suitable for high hydrostatic pressures. Cavitation erosion experiments can be conducted in an ultrasonic cavitation system composed of a spherical cavity focused transducer with high acoustic energy in a sub-wavelength focal region. Quantitative analysis of cavitation pit morphology can be achieved through the proposed microjet impact model. A microjet velocity inversion model was proposed to quantitative evaluate the cavitation erosion intensity.

“…Finally, at the border of the exposed area, the NP multilayer appears clearly, with holes resulting from cavitation (zone 3 in Figure c,f). This damage pattern is representative of the erosion process usually observed for bulk materials or thin coatings, which results from the multiple impacts of cavitating bubbles. ,,, …”

“…This damage pattern is representative of the erosion process usually observed for bulk materials or thin coatings, which results from the multiple impacts of cavitating bubbles. 13,25,37,38 In the following, an experimental estimate of the relative cohesive energy density of the NP assembly is given on the basis of the surface area of multilayer removed by ultrasonic cavitation. For this, optical microscope images of the sample after each sequence of ultrasonic testing were thresholded and the surface area of the observed bare silicon substrate normalized by the area of the sonotrode tip (Figure 3b).…”

Experimental Characterization of the Nanoparticle Size Effect on the Mechanical Stability of Nanoparticle-Based Coatings

We present an experimental investigation of the mechanical stability of silica nanoparticle-based coatings as a function of the size of the nanoparticles. The coatings are built following a layer-by-layer procedure, alternating positive and negative surface charges. The mechanical stability of the multilayers is studied in water, on the basis of an ultrasonic cavitation test. The resistance of the coating to cavitation is found to remarkably increase with decreasing the size of the nanoparticles, indicating an increase of the cohesive energy density. The relative contribution of van der Waals and electrical double-layer interactions to the stability of the multilayer is discussed toward their size dependence.
