Science Daily February 23, 2023 Often, the progression of localized corrosion is accompanied by the evolution of porosity in materials previously reported to be either three-dimensional or two-dimensional. Using new tools and analysis techniques, a team of researchers in the US (Lawrence Berkeley National Laboratory, Pennsylvania State University, MIT, Pacific Northwest National Laboratory, University of Virginia) realized that a more localized form of corrosion, which they call 1D wormhole corrosion, has previously been miscategorized in some situations. Using electron tomography, they showed multiple examples of 1D and percolating morphology. To understand the origin of this mechanism in a Ni-Cr alloy […]
