Abstract

Pour protéger un acier inoxydable ferritique contre la corrosion par fissuration et par piquage dans un environnement corrosif, on en recouvre une portion avec un autre acier inoxydable qui est moins noble que l'acier ferritique dans l'environnement corrosif.To protect a ferritic stainless steel against cracking and pitting corrosion in a corrosive environment, a portion is coated with another stainless steel which is less noble than ferritic steel in the corrosive environment.
