displays the highest power density and anodic utilization compared with the others in 4 mol/L KOH solution. Key words: aluminum anode; zirconium oxide nanoparticles; electrochemical impedance... anodic slope (βa). To explain the effect of nano-zirconium oxide particles, the base alloy structure should be studied. Tin particles have strong effects on the aluminum activation and are present......
Long-term deterioration of lubricant-infused nanoporous anodic aluminium oxide surface immersed in NaCl solutionDequan Wu1,Lingwei Ma1,Bei Liu1,Dawei Zhang1,Badar Minhas1,Hongchang Qian1,Herman...:This study investigated the deterioration of a lubricant-infused anodic aluminium oxide surface in a 1M NaCl solution for ~200 days. Direct observation......
on high-strength aluminum alloy can raise evidently the resistance of atmospheric corrosion. Cl- can promote pitting generation on the oxide film of LY12 when exists, LY12 can react much intensely... in dissolution of oxide film in acidic media. The sulphate aluminum film forms on surface of sample exposed to 0.02 mol/L NaHSO3+ 0.006 mol/L NaCl under the action of H+, and Cl- together, which makes polarization......
of the MAO coatings are small and compact, and the corrosion resistance of oxide coatings is increased largely. Key words: 2024 aluminum alloy; KMnO4; microarc oxidation; microstructure; corrosion... cylinder, naval ships and craftwork [10-11]. However, up to now, the way of acquiring proper thickness of oxide coatings on aluminum alloy is to increase the voltage or prolong the disposal time......
Fabrication and characterization of anodic oxide films on a Ti-10V-2Fe-3Al titanium alloyJian-hua Liu,Jun-lan Yi,Song-mei Li,Mei Yu,and Yong-zhen Xu School of Materials Science and Engineering,Beihang University,Beijing 100191,China摘 要:Anodic oxide films of the titanium alloy Ti-10V-2Fe-3Al in ammonium tartrate electrolyte without hydrofluoric acid......
and the deposit by reduction exist, and the behavior of this deposit is based on the formation of the nonuniform oxide film on aluminum substrate[10]. After the pickling by 5% HNO3 solution, Al-Zn alloy layer on the surface, which is formed by the diffusion between zinc deposit and aluminum substrate, seems to suppress the passivation of aluminum substrate, and thus the oxide film dissolves immediately......
