Drugs: A review of promising novel corrosion inhibitors

Abstract

Due to the toxicity of widely used corrosion inhibitors and the ever tightening environmental regulations surrounding their use and disposal, there is great interest in replacing harmful inhibitors with effective non-hazardous alternatives. Over the past two decades, extensive research and development have led to the discovery of new classes of corrosion inhibitors, and the importance on the use of several drugs as corrosion inhibitors has grown. This review presents most of the contributions made to the literature on the use of drugs as corrosion inhibitors of various metals in recent years. (C) 2011 Elsevier Ltd. All rights reserved.
