Understanding the effect of surfactant aggregation on corrosion inhibition of mild steel in acidic medium

Corrosion inhibition by surfactant molecules is related to the surfactant's ability to aggregate at interfaces and in solution. Understanding the factors that affect aggregation as well as the state of aggregation of surfactant molecules on metal surfaces is, therefore, an important prerequisite to understanding corrosion inhibition by surfactant molecules. This article investigates the relationship between surfactant aggregation and mild steel corrosion inhibition in acidic medium using cetyl pyridinium chloride and cety trimethyl ammonium bromide.
