With the aid of a sketch, describe the mechanism of crevice corrosion of metals. In your answer, you should indicate the location of the different reactions, give the equations for the reactions, and state the condition for a crevice to continue to grow.
condtions to crevice to grow
1) presence of elctrolyte like NaCl and other incerases the rate of corrosion and crevice will grow
2) differential concentarioan of chemicals like Oxygen and other electrolyte increases rate of crevice corrosion
3)presence air , moisture also increases crevise corrosion
