Abstract

A model for the relationship between the healing time of the scratched diamond-like carbon (DLC) film and the localized corrosion incubation period of metal was established. Based on model calculations combined with experimental results, the scratched DLC film on 13Cr stainless steel was able to heal within 10–16[Formula: see text]h in NaCl solution with an adsorbent-type corrosion inhibitor. However, the localized corrosion incubation time was 30–40[Formula: see text]h. Healing of the scratched DLC film can be completed before localized corrosion occurs. This model provides a theoretical reference for the scratch-repassivation of inert films in corrosion inhibitors solutions.
