anodic reaction

anodic reaction

[ə′näd·ik rē′ak·shən]
(metallurgy)

It is seen that the plating over potential instantly goes back to positive and thus the anodic reaction of equation 1 will dominates and the plated lithium converts to lithium ions and re-insert in graphite through two steps of electrochemical reactions.
The purpose of many corrosion inhibitors is to prevent or retard the anodic reaction.
0008 volts/pH between 4 and 10 does not correspond to any known single solution oxidation process and it is likely that the anodic reaction is a mixture of anodic oxidation of hydrogen that was adsorbed onto the platinum electrode at -1.
In this study, the cathodic reduction of oxygen was thought to be dominant and the effect of the anodic reaction at the scratch was presumably small.
Hence, for study of the corrosion mechanism of pure aluminum in alkaline solution, it is enough to consider indirect metal dissolution by consecutive film formation and dissolution as a partial anodic reaction.
In MMCs reinforced with conducting materials, the presence of less conductive phase at the interface is quoted [23] as not providing an easier path for electron exchange for oxygen reduction and driving the anodic reaction at a higher rate.
The metabolically produced sulfide was oxidized directly at electrode, providing an anodic reaction that produces sulfate or thiosulfate.
Corrosion, in what is known as an anodic reaction, involves the movement of metal from a surface into a solution as an electrically charged species.
At the graphite anode, the main anodic reaction in the electrophoretic cell is the decomposition reaction of water to produce [H.
A strongly spontaneous or prevalent cathodic reaction can push a sluggish anode towards corrosion or a very sluggish cathodic reaction can be used to hinder a very spontaneous anodic reaction.
4), (16) So, it can be concluded that PAni coatings on active metals like iron provide anodic protection, act as electronic, chemical, and physical barriers to inhibit anodic reaction, and maintain high resistance to ionic flow--thereby blocking the metal dissolution and providing excellent corrosion protection.
