Correlation between the histogram and power spectral density analysis of AFM and SKPFM images in an AA7023/AA5083 FSW joint

Journal of Alloys and Compounds, 2018
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 ...

Multiscale electrochemical study of welded al alloys joined by friction stir welding [PDF]

, 2017
Friction stir welding (FSW) is an efficient way to join high strength aluminum alloys. However, FSW generates different microstructural areas in contact that may give rise to galvanic couplings, affecting the corrosion resistance of the assembly.

The localised corrosion associated with individual second phase particles in AA7075‐T6: A study by SEM, EDX, AES, SKPFM and FIB‐SEM

Materials and Corrosion, 2017
To investigate the role of intermetallic particles in the localised corrosion of AA7075‐T6, three particles were monitored over 16 h immersion in 3.5 wt% KCl solution. These were examined using Auger electron spectroscopy, energy dispersive X‐ray spectroscopy, scanning Kelvin probe force microscopy and focused ion beam‐scanning electron microscopy ...
