Stress‐induced Corrosion on Metals Protected by Surface Coatings There are several methods of protecting the surface of base metals against corrosion agents. Partly, layers will be applied and cause a tight seal as in the case of synthetic resin varnish, and partly, due to the atmosphere metals (such as Cr‐alloyed, corrosion‐resisting steels or aluminium) protect themselves with a dense coat of oxide, if these surface coatings will be damaged, an increased corrosion would be caused. However, the oxide skin generally heals up rapidly. It is not known, whether resistance against cyclic loading would considerably be affected by damaged surface coatings as a result of cyclic strain. This question need not be raised in that, the application and, therefore, the investigation of such metals without surface coatings is uninteresting from the technical point of view.
