Mechanisms involved in the destruction of insulating films on metal surfaces in electrolytes were investigated. Loss of corrosion-protective properties of the film was found to be due primarily to penetration of the electrolyte, through film pores and defects, onto the metallic surface.
The electrochemical nature of the metal and magnitude of its corrosion potential in the particular electrolyte are other important factors in the initial deterioration of the insulating film.
