Micro-organisms live in jet fuel which are contaminated with water and iron oxides of mineral salts. Slime is formed by these fungoid creatures which often serve as excellent electrolytes and promotes excessive corrosion. |

From the standpoint of corrosion prevention, it is
necessary to keep aircaft fuel tanks clean and use only clean, water-
free fuel. Water condensate must be drained from the fuel tank
frequently. Further, fuel storage facilities should be monitored
to ensure that the fuel is clean.Biocide treatment may be used for
control of micro-organism in jet fuel tank.
Metallic mercury corrosion on aluminum alloys. A number of airlines have experienced this phenomenon. It is quite serious once started the corrosive action is rapid in both pitting and intergranular attack and very difficult to control. Radiographic inspection has been used to locate the small particles of spilled mercury. |

| Corrosion of ferrous metals. | |||
| One of the most familiar types of corrosion is ferrous oxide | |||
| Corrosion of aluminum and aluminum alloys. | |||
| Corrosion attack on aluminum surfaces is usually quite obvious. | |||
| Corrosion of magnesium alloys. | |||
| Magnesium is the most chemically active of the metals used,. | |||
| Treatment of titanium and titanium alloys. | |||
| Attack on titanium surfaces is generally difficult to detect | |||
| Protection of dissimilar metal contacts. | |||
| Certain metals are subject to corrosion when placed in contact with other metals | |||
| Processes and materials used in corrosion control | |||
| Aircraft parts are almost always given some type surface finish | |||
| Chemical treatment. | |||
