Concentration and coating time effects ofN-acyl sarcosine derivatives for corrosion protection of low-carbon steel CR4 in salt water – defining the window of application

Abstract: Potential natural and environment-friendly substances are often used as substitutes for inhibitors to protect steel against corrosion in a sustainable way. Here, three biodegradable N-acyl sarcosine derivatives are evaluated for corrosion protection by polarisation, weight loss, electrochemical impedance, optical and scanning electron microscopy (SEM) spectroscopy including energy dispersive spectroscopy (EDS) to find the best possible application interval of concentration and dip-coating time. The substances … Show more

“…Ochoa et al [31][32][33] investigated the synergistic effect of a combination of fatty amines containing oleoyl residues together with phosphorus-containing carboxylic acids on the corrosion reduction of carbon steel and classified them as mixed type inhibitors. As reported in recent works, the efficiency of an inhibitor system composed of sarcosine amino acid and fatty residues reduces corrosion as a function of carbon chain length, molecular weight, its concentration, and the dip coating time of steel in the inhibitor solution needed for surface adsorption [6,34]. The linkage between the polar sarcosine and the hydrocarbon chain of the fatty acid improves the overall solubility in many solvents and increases the acidity of the carboxyl group, resulting in better adsorption than free fatty acid [17].…”

“…As detected by GC-MS (Thermo Finnigan Q-GC, GCQ/Polaris MS, Thermo Fisher Scientific Inc., Waltham, MA, USA) the present, natural composed compound C contained the following as main fatty residues: 3.1% C 8, 4.2% C 10, 41.8% C 12, 18.9% C 14, 9.7% C 16, and 9.3% C 18. Stock solutions for the dip coating were provided at four concentrations (25,50,75, and 100 mmol/L) of both single compounds in toluene (see Supplementary SI 1) [34]. For the inhibitor combinations C + OI, respective stock solutions were combined in 50:50 volume percent so that they finally had the same molecular concentrations (25,50,75, and 100 mmol/L).…”

“…This is directly associated to the sorption of TOE compounds at carbon steel surface. It is noteworthy that the surface of the material exposed to TOE-seawater is homogenous: this means that the surface is totally covered by TOE extract (at least at 400 mg L −1 TOE dosage); indeed, a partial coverage of the surface would show inhomogeneity in the distribution of coating aggregates 63 .…”
