Enhancing the pitting resistance of AISI 430 stainless steel by laser treatment

Abstract

The paper proposes a method of laser treatment of the steel sur-face for protection against the formation of electrochemical corrosion.AISI 430 stainless steel plates were used in the work. The influ-ence of laser structuring on the contact angle and the interactionof laser-structured steel surfaces with an aggressive environment dur-ing corrosion tests are considered. The composition of oxides formedafter laser treatment, as well as the roughness of the modified sur-face, are considered. Positive dynamics in protection against pittingcorrosion formation on the surface of metals have been revealed.
