Corrosion is the natural degradation of a metal or alloy due to the reaction with the environment to which it is exposed.

Corrosion can show different forms, of which three main categories stand out:

  • Group I: those that can be identified by visual inspection.
  • Group II: those that require additional evaluation methods.
  • Group III: those that should be verified by observation and laboratory analytical techniques.

Identifying corrosion shapes and failures requires specific knowledge, analytical resources, and experience.
