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

The paper proposes a method of laser treatment of the steel surface for protection against the formation of electrochemical corrosion. AISI 430 stainless steel plates were used in the work. The influence of laser structuring on the contact angle and the interaction of laser-structured steel surfaces with an aggressive environment during corrosion tests are considered. The composition of oxides formed after laser treatment, as well as the roughness of the modified surface, are considered. Positive dynamics in protection against pitting corrosion formation on the surface of metals have been revealed.
