Nanosecond pulsed laser-assisted modified copper surface structure:Enhanced surface microhardness and microbial corrosion resistance
文献摘要：
Microbiologically influenced corrosion(MIC)is an unavoidable problem in several industries.Copper(Cu)and its alloys are widely used engineering materials.However,MIC of Cu remains a persistent chal-lenge to their performance and functional lifetime under aggressive environments.This study investi-gated nanosecond pulsed laser processing(LP),which may enhance the corrosion resistance of Cu.The microstructural evolution and corrosion behavior of LP-Cu in the presence of sulfate-reducing bacteria(SRB)were evaluated.Typical deformation-induced microstructural features of high-density dislocations were analyzed on the top surface of LP-Cu coupon.Electrochemical measurements suggested that LP-Cu coupons exhibited better corrosion resistance in SRB-inoculated solution compared with their original counterpart.The enhanced corrosion resistance by LP primarily resulted from the combined influences of compressive residual stress and work hardening in the surface.However,overlap percentage played a key role in improving corrosion resistance.LP produced optimal corrosion resistance at 50％overlap.There-fore,this study introduces a unique and an option for anticorrosion control in manufacturing processes and potentially implements it onto other materials to improve its microbial corrosion resistance through LP.
