Hall–Héroult process Wikipedia
Anode effect. Anode effect is a situation where too many gas bubbles form to the bottom of the anode and join together forming a layer. This increases the resistance of the cell when smaller areas of the electrolyte touch the anode.

Metallurgy Extractive metallurgy |
The basic oxygen furnace (BOF) is a vessel used to convert pig iron, of about 94 percent iron and 6 percent combined impurities such as carbon, manganese, and silicon, into steel with as little as 1 percent combined impurities. The BOF is a large pearshaped unit that can be tilted to charge and pour.

Cathode: O2 + 4e– → 2O2 (1) Anode: C + 2O2 → CO2+ 4e– (2) The fuel is housed on the anode side of the membrane with air being used as the oxidant on the cathode side. The oxygen molecules become ionized [reaction (1)], and the oxygen ions flow across the membrane and react with the fuel to produce CO2 [reaction (2)].

Metallurgy Material Engineering: Types of Corrosion
6. Corrosion of pipeline TYPES OF CORROSION Basically, there are four ways corrosion can occur. Corrosion can occur through a chemical reaction or three general types of electrochemical reactions. The three general types of electrochemical reactions that occur depend on the cause of the potential difference between the anode and the cathode.
