Metal pitting corrosion characterized by scanning acoustic microscopy and binary image processing

[Display omitted] •SAM for detecting the localized corrosion degree of the metal under the rust layer is firstly reported.•Combined TAMI scanning with image processing method, the pitting depth can be characterized.•Under the C-scanning mode, one single pit on the 7050 aluminum alloy can be focused....
