The samples were strengthened by embedding Al2O3 nanoparticles with the energy generated by cavitation-bubble collapse and then a strengthening model was established to perform test verification. By utilising a microhardness tester, a scanning electron microscope (SEM), an X-ray diffractometer (XRD), and an X-ray photoelectron spectrometer (XPS), various parameters (e.g. microhardness, surface morphology, phase composition, element content, and chemical state) of the strengthened samples were analysed. The result showed that, after experiencing the combined effect for 5 min, nanoparticles appear on the sample surface observed under the SEM; by applying the XRD and XPS, it is found that the Al2O3 content in the samples increases, implying that Al2O3 particles have been embedded in the sample surface. The microhardness of the samples improves by 29.1 HV. In terms of the strengthening mechanism under the combined effect, the energy generated due to cavitation-bubble collapse is transferred to Al2O3 particles to enable these particles to strike the sample surface. Thus, the samples suffer from more gentle impact and the transition zone with pits formed on the sample surface is significantly smoother and more continuous; moreover, the samples are further strengthened after Al2O3 nanoparticles are embedded within the sample surface as these nanoparticles present high strength and microhardness, however, with increasing duration of the strengthening process, the failure characteristics of surface morphologies of the samples gradually develop, as observed through the SEM; after experiencing the combined effect for 10 min, a large area of the surface is damaged. XRD and XPS results indicate that Al2O3 particles induce a decrease in the binding capacity with the surface layer of the samples and thus gradually separate from the samples. Therefore, the properties of the samples are adversely affected.
