Corrosion inhibition by anionic surfactants of AA2198 Li-containing aluminium alloy in chloride solutions

In general, these substances stifled both the cathodic and anodic processes and noticeably shifted the pitting potential (breakdown potential, EBR) in the positive direction. The most efficient compounds were N-lauroylsarcosine sodium salt and sodium dodecyl-benzenesulfonate, able to withstand the effects of 0.1 M Cl−.
