| corrosion | corrosion is the electrochemical deterioration of a material or its properties due to its chemical reaction with the surrounding environment |
| Galvanic Corrosion | occurs when different metals are in contact with each other and an electrode such as sea water |
| Pitting | usually first noticeable as a white or gray powdery deposit, similar to dust, which blotches the surface |
| Intergranualar corrosion | is an attack on the grain boundaries of the metal |
| nickel corrosion | Green powdery deposit |
| What type of corrosion is probably the most common type of corrosion? | Uniform surface corrosion |
| In order to prevent corrosion there must be a constant cycle of what four activities? | Cleaning, Inspections, Operational preservation and lubrication |
| Filiform corrosion occurs on what types of metals? | Steel, Aluminum and magnesium |
| What type of metal is used as protective plating on aircrafts? | Chromium |
| Erosion Corrosion | Accelerated attack of a metal due to the relative movement between a fluid and the metal surface. |
| Fretting | Corrosion which occurs at the interface of two mating surfaces, under load and subjected to vibration and slip. The relative motion between the two surfaces is extremely small |
| Uniform Surface Corrosion | Corrosive etching of metal involving only the surface. |
| Magnesium Corrosion | white powdery snow-like mounds |
| steel corrosion | red rust |
| aluminum corrosion | pitting |
