Unifonn corrosion

Localized corrosion is far more treacherous in nature and far less readily predictable and controllable tlian unifonn corrosion and it is, moreover, capable of leading to unexpected damage witli disastrous consequences, especially since inspection of corrosion damage is in many cases difficult. 

Genera) (unifonn) corrosion is normally associated with spatially and temporally random cathode and anode zones on a homogeneous metal suiface (Table 10.4). In practice, the corrosion engineer is generally much more concerned with situations where corrosion is accelerated because it is limited to particular sites... 

In the following, the most typical modes of corrosion—other than the above discussed unifonn dissolution (active corrosion) and localized pitting and crevice corrosion (local active dissolution)—are briefly presented.
