Gases are produced by oxidation, vaporization, insulation decomposition, oil breakdown and electrolytic action.
2.
Similarly, electrolytic action may also be caused by installing bare-sheath MICC cables on new oak.
3.
However, because of the problem of electrolytic action in salt water ( also known as Galvanic corrosion ), in shipbuilding Monel must be carefully insulated from other metals such as steel.
4.
However, where MICC cables with a bare copper sheath are installed in damp locations, particularly where lime mortar has been used, the water and lime combine to create an electrolytic action with the bare copper.
5.
In 1824 to reduce the impact of this destructive electrolytic action on ships hulls, their fastenings and underwater equipment, the scientist-engineer Sir Humphry Davy, developed the first and still most widely used marine electrolysis protection system.
6.
To prevent corrosion due to electrolytic action all fixings to the roof structure have been electrically isolated from the aluminium castings with plastic washers etc . Examples of identical original cast iron crestings may be seen adorning Slough railway station, Wrexham General railway station and the HSBC Bank in Derby city centre.
7.
There is also electrolytic action causing ferrous metal underground to lose metal when copper is nearby, but that should not depend on AC versus DC current in the copper, as long as the circuit has a return path and is not just unipolar . talk ) 20 : 43, 1 February 2010 ( UTC)
