Wavelet analysis and bispectrum was applied to Acoustic Emission (AE) signals from
scratch tests on corroded hot-dip galvanized samples in order to achieve the detection of corrosion
products in pieces non reachable by visual inspection. AE signals were correlated with the fracture
mechanisms occurring during scratch tests, while the contact force increased. Results were
corroborated by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray spectroscopy
(EDX) and X-Ray Diffraction (XRD).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
