Steel protection by the use of piper betle leaf extract
A recently published work proposes a new inhibitor that can be added to a green corrosion inhibitor system for delivering high corrosion resistance of steel.
Leaf extracts are widely used to mitigate the steel corrosion in an acidic environment. A new work focuses on the effective acidic inhibition of a piper betle leaf extract (PBLE) that can be added to a green corrosion inhibitor system, giving a high corrosion inhibition performance of steel in a 0.1 M HCl solution.
Increased inhibition efficiency
Surface analysis demonstrated that a nano porous film formation is PBLE concentration dependent. Test results indicate that the inhibition efficiency is increased by the addition of PBLE at a concentration up to 2000 ppm due to a compact, robust, and uniform protective film formation. Moreover, an increase in PBLE concentration up to 2500 ppm decreased the inhibition efficiency due to a decrease of the PBLE species’ activity in the solution that significantly affects the nano porous film formation.
The study has been published in Progress in Organic Coatings, Volume 158, September 2021.
