What Are The Differences Between Chemical And Electrochemical Corrosion?

Answer»

Chemical corrosion:

  1. It occurs dry state
  2. Local attack to metal by environment
  3. Chemical corrosion is self-controlled
  4. It follows adsorption mechanism
  5. Ex: formation of mild scale on IRON surface

Electrochemical corrosion:

  1. Wet state (i.e) presence in MOISTURE
  2. Large number of CATHODIC and anodic AREAS
  3. It is continuous PROCESS
  4. It follows electrochemical reaction
  5. Ex: rusting of iron in moisture
