The inhibition of copper corrosion in cooling seawater by novel pyrophosphate SrNiP 2 O 7 (SNP) was investigated under flowing conditions using mass-loss and electrochemical methods. The surface morphology was characterized by SEM coupled with EDX spectra. Comparable results show that SNP acts as a mixed-type inhibitor with predominantly cathodic effectiveness, suppressing the corrosive process by physical adsorption on the copper surface. The highest inhibition efficiency obtained from mass-loss, polarization and EIS measurements are 92.7%, 94.8% and 97.1%, respectively, at 120 mg L À1 of SNP. The influence of increasing temperature on SNP inhibitor efficiency has been studied, and the activation energy has been calculated. Surface morphology observations evidenced the formation of a protective SNP film over the metal surface.

“…The S element is present for TTC‐Cu surface after corrosion, but absent for Cu surface after corrosion. This is probably assigned to the electrostatic interaction between the triazole molecules and aggressive ions such as Cl − and SO 4 2− . The TTC film has the ability to hold these aggressive ions and retarding their attack towards the inner copper.…”

The triazole inhibitor of 1‐(p‐tolylthio)‐1H‐1,2,3‐triazole‐4‐carboxylic acid (TTC) was synthesized via the Cu(I)‐catalyzed azide‐alkyne 1,3‐dipolar cycloaddition reaction. The self‐assembling method was performed to fabricate the self‐assembled film of TTC on the copper surface. The electrochemical measurement results indicate that the TTC film can efficiently protect the copper from corrosion in high concentrated industrial cooling water. The protection efficiency of TTC film for copper is 92.2%. Surface characterizations imply that the copper with TTC film after corrosion is covered with multiple protective layers. It probably contains Cu(I) and Cu(II) complexes mixed with nitrogenous compound, Cl− and SO42−. The result of quantum chemical calculation shows that the superior performance of TTC film is related to the adsorption of TTC molecules on copper surface horizontally. This kind of adsorption is mainly achieved via the adsorption centers of triazole ring and O atoms in TTC molecule.

The inhibiting action of a novel inorganic compound (NaCo(H 2 PO 3 ) 3 $H 2 O) (NaCoPh) synthesized in our laboratory on the corrosion of aluminum in engine coolant solutions has been studied. In this study, potentiodynamic polarization measurements with SEM/EDX investigations were employed. Polarization curves reveal that NaCoPh is a mixed type (cathodic/anodic) inhibitor for aluminum corrosion in the engine coolant solution. The inhibition efficiency increases with increasing concentration of NaCoPh but decreases with increasing temperature and flow rate. SEM/EDX investigations reveal the adsorption of NaCoPh on the aluminum surface. A mixed adsorption (physisorption and chemisorption) for NaCoPh was proposed.
