The NACE TM0208-2018 Jar Test remains an industry-wide recognized standard for evaluating the vapor-inhibiting ability (VIA) of raw materials and finished products to provide off-contact corrosion protection of steel surfaces1. It is particularly useful for comparing the efficacy of different VCI chemistries, as well as for monitoring performance consistency between productions of VCI functionalized materials.

Corrosion is common, costly and a prevalent industrial problem in the oil and gas industry. Corrosion inhibitors, which are surfactant-like molecules, adsorb on the metallic surface of a pipe to form a barrier film that inhibits interactions of the pipe surface with corrosive species. Despite the prominence of surfactants as corrosion inhibitors, their adsorption behavior inside a pipeline is not well understood. In this study, continuous corrosion inhibitors were evaluated to correlate corrosion performance testing with contact angle and surface tension studies. Contact angle method was employed in corrosion inhibition studies for surface characterization. Surface tension method was used to determine critical micelle concentration. Contact angle results showed that for the water-soluble continuous corrosion inhibitors such as quaternary ammonium and imidazoline, a monolayer and bilayer were formed on the metal surface as reflected by an increase and then decrease in contact angle. The bilayer further increased the corrosion inhibition efficiency until the critical micelle concentration (CMC) was reached for quaternary ammonium and imidazoline only. However, the mixed quaternary ammonium and imidazoline in the formulation resulted in the maximum contact angle value being at its CMC indicating a compact monolayer formation. The results can provide a helpful guideline for further studying the synergistic effect of corrosion inhibitor mixtures.
