Organic Inhibitors of Corrosion of Metals
The use of computational chemistry as a tool in the design and development of organic corrosion inhibitors has been greatly enhanced by the development of density functional theory DFT. Moreover, the testing conditions and the methodology used for corrosion inhibition performance evaluation are presented.
The impact of this review is to illustrate the enormous power of DFT and to identify organic corrosion inhibitors pdf download in past work, including the assumption that inhibitors only interact with bare metal surfaces. Thus, ongoing hardware and software advances have opened the door for powerful use of theoretical chemistry in corrosion inhibition research at a reduced cost.
Whereas, traditionally, corrosion scientists have identified new corrosion inhibitor molecules either by incrementally changing the structures of ocrrosion inhibitors or by testing hundreds of compounds in the laboratory, these experimental means are often very expensive and time-consuming.

Weight loss and electrochemical techniques were among the most frequently used techniques to evaluate the corrosion inhibition effectiveness of the studied compounds. The paper also organic corrosion inhibitors pdf download the principles upon which modern corrosion science is based with emphasis on corrosion in the oil and gas industry and with the goal of identifying important issues in the design of new, more effective inhibitors in this field.
