Abrasive blasting of steel using garnet is a commercial surface cleaning procedure, for removing old corrosion scales and paint prior to the application of new coatings. A certain percentage of the garnet and its impurities remain attached, partially covering the steel. Between cleaning and repainting, seawater aerosol droplets can impact the steel and initiate corrosion, which may subsequently lead to coating failure. An innovative approach for the deposition of corrosion inhibitors on steel is proposed, making use of material deposited on the steel during abrasive blasting. This aims to immediately protect the steel from corrosion after cleaning until repainting, to improve the longevity of coatings. The optimum approach to deposit a suitable corrosion inhibitor onto the steel as part of the blasting process was investigated. A selection of anti-corrosive materials were mixed with garnet and tested in abrasive blasting. Material deposition was analysed by electron microscopy and the inhibition efficiencies of the treatment determined in electrochemical corrosion tests. It was found that the impact of garnet particles effected the required cleaning, whilst anti-corrosive materials were successfully deposited on the steel. A correlation was observed between the proportion of the anti-corrosive agent in the blasting mixture and the amount deposited. Direct addition of tannic acid, a solid-state green inhibitor, into the abrasive improved the corrosion resistance of steel by up to 80% for at least 8 h. Commercial encapsulation products can be repurposed for abrasive blasting, showing inhibition efficiencies of up to 65%. Further encapsulation methods were investigated for corrosion inhibitor retention and performance in abrasive blasting. Silica capsules with various shell morphologies and high mechanical stability were prepared. Post-preparation loading of macroporous capsules, with high void volumes, presented a versatile and efficient way of encapsulating inhibitors that cannot be directly mixed with garnet, such as benzotriazole (BTAH). After blasting, BTAH was released from deposited capsules upon contact with a solvent and spread to cover the steel surface, as required for corrosion protection. The extent and strength of adsorption of BTAH from toluene onto steel, iron oxide, garnet, calcium carbonate and silica are presented, including solution self-association corrections for the inhibitor. X-ray photoelectron spectroscopy, sum-frequency generation spectroscopy, and quartz crystal microbalance measurements supported the solution depletion conclusions: for low bulk concentrations, BTAH preferentially adsorbs onto steel, even in the presence of other minerals, due to the increased adsorption strength. With higher availability of BTAH, the other substrates can adsorb significant amounts, in fact, more than S355 steel. However, under this regime, the steel and iron are still expected to have a complete monolayer of BTAH and the corrosion inhibition efficiency should not be affected.
