Selection of an appropriate corrosion inhibitor, inhibitor combination or package is an exceptionally cost effective and materials saving measure in various industries. The article reviews recent (2008-2010) patents reported on corrosion inhibitors. Up-to-date developments in the inhibition technology are presented in accordance with the areas of application of inhibitors - industrial cooling water systems, oil and gas fields, coatings, acid pickling, lubricants, vapor phase inhibition, concrete corrosion etc. Nanotechnological advancements in inhibitor technology (in coatings) and novel products employing vapor phase corrosion inhibitors were discussed.
Keywords: Corrosion inhibitors, cooling water systems, oil and gas field, paint and coatings, smart coatings, vapor phase inhibition, concrete corrosion, inhibitor technology, inorganic inhibitors, alkylalkanolamine based compounds, Catalytic polymerization, chromate based coatings, chromate-free corrosion inhibiting additives, steel corrosion inhibitor, oil aldehyde, chromate aqueous corrosion, aluminum hydroxides
