Multifunctional corrosion inhibition of brass by interface engineering based on ternary layer-by-layer self-assembly with trivalent cerium captured
Source abstract
Abstract
A nanoscale ternary layer-by-layer self-assembly (LbL) thin film was fabricated on brass via a simple dipping method. Dual driving force of intermolecular interactions and coordination realized the high homogeneous dispersion of Ce 3+ , thereby improving the controlled distribution and release of inhibitors. Compared to previous nanometer-thick conversion coatings, ternary LbL film exhibited excellent multifunctional corrosion protection. The maximum strengthening reached 496.8 % in impendence, and corrosion inhibition efficiency remained 95.0 % after a 10-day exposure in 3.5 wt% NaCl. These improvements originated from dynamic barrier effect by crosslinked gel film of PA/PAH and the surface passivation through interface deposition of Ce species.
