Correlation between the histogram and power spectral density analysis of AFM and SKPFM images in an AA7023/AA5083 FSW joint
Abstract
Microstructural and Volta potential behavior of a friction stir welded dissimilar joint of AA7023 to AA5083 has been investigated. Interfacial regions were characterized by SEM-EDS, AFM, SKPFM and optical microscopy techniques. A quantitative correlation between corrosion data from histogram and power spectral density (PSD) analysis, which are related to Volta potential distribution, was established. PSD analysis of SKPFM images showed that the lowest Volta potential in the highest spatial frequency belongs to AA5083, while the highest Volta potential in lowest spatial frequency corresponds to intermetallic particles mainly on AA7023 matrix. Immersion test showed that intermetallic particles in the two matrices, and especially FSW interface, were susceptible to corrosion attack due to a high driving force between these surface constituents.
