Electrochemical Synthesis of Heterocyclic Compounds. Part 21.1 Anodic Oxidation of 1-Arylmethylenesemicarbazides in Methanol [PDF]

, 1989
Anodic oxidation of 1-arylmethylenesemicarbazides (1-5) was performed in methanol-tetraethylammonium perchlorate electrolyte solution by constant-current electrolysis. As a result of anodic oxidation, the corresponding oxadizoles (la-3a) were isolated

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 ...

High-Pressure Torsion and Anodic Oxidation as a Method for Surface Engineering of Ti-13Nb-13Zr Biomedical Alloy

Metals
The anodic oxidation technique was used for surface modification, resulting in the creation of a titanium-based nanotube oxide layer on a coarse-grained and ultrafine-grained Ti-13Nb-13Zr alloy. The modified surface morphology was analyzed using scanning
