Non-toxic Schiff bases as efficient corrosion inhibitors for mild steel in 1 M HCl: Electrochemical, AFM, FE-SEM and theoretical studies

Assessment of Corrosion Inhibition Performance and Adsorption Thermodynamics of Hydrogen Phosphate (HPO42−) and Molybdate (MoO42−) Oxyanions on Tin in Maleic Acid

“…Furthermore, it is noted that that the protonation process of MoO 4 2À and HPO 4 2À follows a reduction of ΔE, which involves less reactivity of protonated species. A similar tendency was described elsewhere for several inhibitor compounds [42,43].…”

Electrochemical Behaviourof Some Amino Acids as Corrosion Inhibitors for Mild Steel in Sweet Brine

“…In Figure 12 can be appreciated the surface morphology images of the polished AISI 1018 steel sample (figure 12a); and the steel sample after 24 h of immersion in the aggressive electrolyte with 10 ppm of Phe (Figure 12b); 100 ppm of Leu (Figure 12c) and 250 ppm of Val (Figure 12d). It can be observed that the polished line of the sample can still be seen after the 24 h immersion in the presence of the three amino acids; meaning that organic molecules adsorbed in those areas forming a protecting layer and inhibiting the metal dissolution; the agglomerations seen in images are associated to corrosion products and NaCl incrustations due to the presence of Na and Cl signals in EDX images [39,40]. The cluster presence in substrate surface validates electrochemical results; since the system with…”

Adsorption and Inhibition Analysis of Aconitine and Tubocurarine Alkaloids as Eco-friendly Inhibitors of Pitting Corrosion in ASTM – A47 Low Carbon Steel in HCl Acid Environment

“…5 and Table 5, the addition of tubocurarine and aconitine alkaloid molecules shifted the corrosion potential (E corr ) values away from the noninhibited solution and also showed changes in both the cathodic and anodic polarization branches and values. These results indicate that the added inhibitors acted as mixed-type inhibitors [26][27]39,[48][49][50].…”
