Book Description
The dissolution of metals in acids is a heterogeneous electrochemical reaction, taking place at the interface between a solid and a liquid, described in terms of energy and configuration of the species involved. The energy of activation for two stainless steels (SSs) in phosphoric acid (PA) was determined from their corrosion rates in the temperature range of 20,Äì120¬∞C, applying the Arrhenius equation. Energy of activation values for the overall process of anodic metal dissolution and cathodic hydrogen release is in the 10,Äì20 Kcal mol,àí1 range. Metal corrosion is a structure-sensitive process; its mechanism and rate are related to the density of surface defects, based on the Boltzmann expression. A model for the activated complex is proposed based on considerations of energy and configuration. This work is an integration of a theoretical analysis and an experimental investigation of metal corrosion in acids.

Book Description
Corrosion is a global threat and a burning topic for new and innovative research. Corrosion causes shut downs, economic losses, delays, failures, accidents, losses of life, and losses in productivity. “Wherever metal is, there corrosion will occur” – this is a general concept as not many protection methods are available to mitigate corrosion. The available methods can only delay the process but cannot stop or protect the metal completely. So there is always a need for good research and inventions in this field. This book includes the recent research work done in the field of corrosion. The chapters are written by reputed authors in the field of corrosion and have been reviewed extensively before acceptance. The chapters focus on different aspects of corrosion to provide readers with a good idea of the overall process. The diversification of the chapters will keep the readers interested and motivated for new innovations in the field of corrosion. It will be very useful to scholars, academicians, researchers, and industrialists.

Book Description
Electrochemistry is the branch of chemistry that deals with the chemical action of electricity and the production of electricity by chemical reactions. In a world short of energy sources yet long on energy use, electrochemistry is a critical component of the mix necessary to keep the world economies growing. Electrochemistry is involved with such important applications as batteries, fuel cells, corrosion studies, hydrogen energy conversion, bioelectricity. Research on electrolytes, cells, and electrodes is within the scope of this old but extremely dynamic field. This volume deals with prevention of metal corrosion.
