摘要

Given the well-documented global corrosion challenge, the development of universal coating systems for metals that provide both passive and active protection is desirable. The active part of such systems typically consists of either polymer precursors or efficient corrosion inhibitors contained inside small capsules disseminated throughout the coating. In both cases, coating rupture and the onset of corrosion trigger a release of the active molecules, which can either physically repair the passive coating or form a thin impermeable film over the exposed metal surface. Previous work in our group has focused on the use of corrosion inhibitors; the technology is well-established for aluminium surfaces and typically employs a hybrid sol-gel film as the coating matrix. However, despite some effort, no similarly effective system has been found for steel.'4'11' When applied to steel the same sol-gel film tends to form a noticeably permeable coating that is highly susceptible to corrosive attack.'4' To improve the passive and active protection of steel, the coating matrix should be nonporous with excellent adhesion and incorporate well-dispersed capsules containing a suitable inhibitor in sufficient quantity. Dense polymer-based coatings are a good option for the passive layer; those incorporating inhibitor directly' or inside capsules have been found to provide excellent passive protection of steel surfaces whilst intact.
