2D-DFA as a tool for non-destructive characterisation of copper surface exposed to substitute ocean water
(2022)Two-dimensional detrended fluctuation (2D-DFA) analysis has been carried out to correlate the Hurst index surface with corresponding irregularities of the cooper surface, because of the localised corrosion attacks after ...
