Anodic oxidation of Al–Ag alloys
Corrosion Science, 2002 The anodic oxidation of solution-treated and quenched Al-Ag alloys containing 0.3, 0.6, 0.9 and 1.2 at.%Ag, is examined in ammonium pentaborate electrolyte, which leads to growth of barrier-type anodic films. Enrichments of silver, ~3.1 × 1015 Ag atoms cm-2, are developed in the alloys immediately beneath the amorphous alumina films, with the level of ...

Active Corrosion Protection of Sintered AA7075 Aluminum Alloy via Mn Powder Addition
Advanced Engineering Materials, EarlyView.AA7075 containing Mn‐rich particles is fabricated via spark plasma sintering using AA7075 and Mn powders. Corrosion resistance is evaluated through dip‐and‐dry tests using 0.1 M NaCl (pH 6.0), and mass loss decreases with increasing Mn addition. Mn‐rich particles function as a source of Mn ions, and formation of Mn‐accumulation films on Cu‐containing ...
