The precursor anodic porous films enable up to 57% energy savings during PEO and produce ~35–40% increase of the coating microhardness compared with direct PEO. Total specific energy consumption values of 2.5–2.7 kW h m−2 µm−1 and 3.1–3.8 kW h m−2 µm−1 were achieved using phosphoric and sulphuric acid-formed precursors, respectively.}, note = {Online available at: \url{https://doi.org/10.1016/j.matlet.2014.04.077} (DOI).
