Evolution of anodic stress corrosion cracking in a coated material [PDF]

open access: yes, 2010
In the present paper, we investigate the influence of corrosion driving forces and interfacial toughness for a coated material subjected to mechanical loading. If the protective coating is cracked, the substrate material may become exposed to a corrosive
