Abstract
Four cationic surfactants have been synthesized in the absence of solvent using triethylamine and four different long chain alkyl halides. Using FTIR, 1H NMR spectra and elementary analysis the chemical structure of the synthesized surfactants were confirmed. The physio-chemical properties have been evaluated using standard analytical procedures. The corrosion inhibition properties of these four surfactants as additives were evaluated on zinc phosphate conversion coating on mild steel using nano silica as accelerator. The efficacy of the surfactants as corrosion inhibitor increases with increase in the side chain length and surface activity. With the help of X-ray diffraction (XRD), Atomic force microscope (AFM) and Scanning electron microscope (SEM) the surface morphology have been studied. The protective performance of the coatings was evaluated by salt spray exposure studies.
Kurzfassung
Es wurden vier kationische Tenside in Abwesenheit von Lösemitteln mittels Triethylamin und vier unterschiedlich langkettigen Alkylhalogeniden synthetisiert. Die chemische Struktur der synthetisierten Tenside wurde mit Hilfe von FTIR, 1H NMR und Elementaranalyse bestätigt. Für die Berechnung der phy-siko-chemischen Eigenschaften wurden analytische Standardverfahren eingesetzt. Die korrosionsinhibierenden Eigenschaften der vier Tenside als Additive wurden anhand der Umwandlung des Zinkphosphatcoatings auf Weichstahl mit einem Nanosilicium als Beschleuniger bestimmt. Die Wirksamkeit der Tenside als Korrosionsinhibitor nimmt mit zunehmender Länge der Seitenkette und Oberflächenaktivität zu. Die Oberflächenmorphologie wurde mittels der Röntgenbeugung (XRD), der Rasterkraftmikroskopie (AFM) und der Rasterelektronenmikroskopie (SEM) studiert. Die Schutzwirkung der Coatings wurde bestimmt, in dem sie einem Salzspray ausgesetzt wurden.
