“…Composite peening significantly increases the roughness of the surface. [17] In this study, the roughness after composite peening was R z ¼ 13.7 AE 2.0 μm, whereas 2.6 AE 0.4 μm was observed prior to the peening process. To close open structures near the surface created by the peening process, the samples were deep rolled at a pressure of 40 bar subsequently.…”

Composite peening is a novel process to introduce ceramic blasting particles into the surface of substrates. Depending on the process parameters, the penetration depth of the blasting particles can be several micrometers. In previous investigations by some of the authors, it has been found that the ceramic particles incorporated during composite peening are significantly smaller compared to 10 μm in size before peening. Herein, the microstructure after composite peening is highlighted. To investigate this microstructure, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are performed. The subsequent X-ray diffraction (XRD) analysis provides further evidence of a severely deformed, nanocrystalline ceramic layer consisting of fragmented blasting particles.

Composite peening offers the opportunity to introduce ceramic blasting particles into metallic base material. By embedding Al2O3 particles, mechanical properties of aluminum can be improved. However, those surface modifications might negatively impact corrosion resistance and thus shorten the lifetime of components. This study analyzes corrosion properties of peened aluminum in chloride solution via immersion, scanning electron microscopy and polarization. The data of observed microstructures indicate that peening accelerates corrosion and that intergranular corrosion is the main force of degradation in contrast with pitting corrosion of monolithic aluminum.
