Quinoline quaternary ammonium salt – KSCN synergy for non-magnetic steel corrosion inhibition in 4 % HCl/HF environments: Film densification and molecular insights

Key Points

• Corrosion inhibition improved when quinoline quaternary ammonium salt and KSCN are combined, leading to enhanced protective effects.
• Key evidence shows a significant reduction in corrosion rates in 4% HCl/HF environments with a dual-action approach.
• Experimental observations reveal film densification occurring on steel surfaces, suggesting increased protection against corrosive agents.
• Findings indicate the need for further exploration of molecular insights to understand the underlying mechanisms at work.
