Abstract

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.
