Describe passivation Passivation is the formation of a protective oxide
Film on the surface reducing its chemical activity
and its ability to corrode
Describe the following factors and Oxygen: oxygen increases the rate of corrosion
how they affect corrosion temperature
Temperature: corrosion usually accelerated with
increasing temperature
Chemical salts: increase the rate of corrosion by
increasing the efficiency of the electrolyte
humidity: the wetter the environment, the more
corrosion is likely to occur pollutants and acid
gases: all promote corrosion
Two broad categories of corrosion General and localized
can be described as
Describe galvanic corrosion Galvanic corrosion is an electrochemical action of
two dissimilar metals in the presence of an
electrolyte and an electron conductive path, Which
occurs when the dissimilar metals come into
contact
