Surface morphology, composition and thermal behavior of tungsten-containing anodic spark coatings on aluminium alloy

Effects of cathode current density on structure and corrosion resistance of plasma electrolytic oxidation coatings formed on ZK60 Mg alloy

“…In recent studies, to produce the serviceable PEO coatings, the amplitude modulated ac and pulsed bi-polar electrical * Corresponding author. sources are widely used [20][21][22][23][24]. In these circuits, the positive and negative biasing alternately function on the samples and this alternation directly determines the discharge formation and discharge interruption in the PEO treatment.…”

Anti-corrosion film on 2024/SiC aluminum matrix composite fabricated by microarc oxidation in silicate electrolyte

“…With this method, the wear and corrosion protective ceramic films can be synthesized on valve metals such as Al, Mg, Ti [8][9][10][11]. At present, most of papers about MAO focus on the treatment of light metals [12][13][14][15][16][17][18], and the corresponding investigation on metal matrix composites is much less [19,20]. It is of great interest to analyze the influence of SiC reinforcements on the continuity and corrosion behavior of the film.…”

Anti-corrosion microarc oxidation coatings on SiCP/AZ31 magnesium matrix composite

“…be fabricated on valve metals such as Al, Mg, Ti [8][9][10][11][12][13]. Some papers about MAO on aluminum matrix composite have been reported [14][15][16].…”
