Sažetak
Wide usage of construction materials often results in their damage, mainly caused by corrosion. As a mean to prevent it, materials are introduced to methods of protection, increasingly by using green inhibitors. The sea is a source of numerous species with potential anti-corrosive properties which are adorned with countless organic compounds. The aim was to study the inhibition effect of aqueous extract of brown alga Padina pavonica (in 0.2% and 0.8% (v/v) concentration) on corrosion of copper, AISI 304 stainless steel and technical aluminium in the 0.5 mol dm–3 NaCl solution. Total phenolic compounds were isolated and determined, the following experiments were conducted using electrochemical methods, while the surface of the samples was analysed using an optical microscope. Results revealed that examined extract can be classified as an efficient corrosion inhibitor for all three metals, especially for aluminium, and 0.8% extract proved to be the more effective one.
