Book Description
In 2007, the Federal Highway Administration initiated a program to develop an improved corrosion resistant steel for highway bridge construction. The ATLSS Center (Advanced Technology for Large Structural Systems) at Lehigh University in Bethlehem, PA was contracted to implement a series of investigations to develop copper-nickel precipitation-strengthened weathering steels with similar or improved weldability and toughness to high performance grade steels as well as enhanced corrosion resistance without the need of protective coating systems. The corrosion properties of the developmental steels were investigated based on electrochemical surface potential and mass loss measurements after exposure of the alloys to accelerated cyclic corrosion protocols in order to discover the effects of elemental additions on the corrosion-products of weathering steel such that a new improved steel composition for highway bridges can be proposed.

Book Description
Electrochemical properties of earthen materials such as electrical resistivity, pH, salt concentrations, and organic contents are commonly used to characterize the corrosion potential of buried metal elements that are in direct contact with the surrounding soil. The TRB National Cooperative Highway Research Program's NCHRP Research Report 958: Improved Test Methods and Practices for Characterizing Steel Corrosion Potential of Earthen Materials proposes a protocol describing best practices for sampling, testing, and characterizing the steel corrosion potential of earthen materials. The protocol incorporates alternatives to the current AASHTO test standards for measuring electrochemical properties.

Book Description
The book entails investigative methods for better understanding of the degradation process and uses of high performance paints formulation and also compares them on mild steel (MS) and weathering steel (WS) through various AC/DC electrochemical test methods and surface characterization through electron microscopy, XRD and Raman spectroscopy. This book also deals with the corrosion studies undertaken considering three phases (solid, liquid and gas) with latest techniques and the emphasis has also been given on degradation of materials due to atmospheric corrosion as this is of immense interest to present engineers and researchers. MS has got versatile application as structural steel for construction of buildings, bridges, flyovers, pipelines etc. But this is very much prone to corrosion in industrial and marine environments in presence of harmful pollutants and other industrial effluents in addition to normal humid atmosphere. These corrosion problems are much severe in a tropical country like India with vast coastline. MS corrodes relatively faster and thus leads to colossal loss in every year and to reduce this loss some kind of protection in the form of paints and coatings is always used. Painting is an effective means but quite costly amounting 10-15% of the initial construction cost of superstructures besides cost of repainting at regular interval.

Book Description
Half cell mapping has for at least fifteen years been the most popular non-destructive methods of investigating the corrosion state of embedded reinforcement. However, although this method is becoming widely used in civil engineering for determining the corrosion state of the steel reinforcement in concrete, there has been very little consideration of the principles and potential measurement. This practical guide explains the principles of potential measurement, shows how these should be undertaken and, most critically, provide ways of interpreting the data.

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.

Book Description
Electrocorrosion, the corrosion of metallic constructions by external currents, is the most significant factor in conductive aggressive environments. Corrosion of underground and underwater metal constructions by stray currents has been comprehensively studied in the past decades and is considered here only in the form of a review. The primary attention is on corrosion, by external anodic (mainly) and cathodic currents, of metal constructions in the highly aggressive environments typical for electrochemical plants, where penetration of the external currents (leakage currents) from the electrolytic baths into metal constructions is unavoidable.A new approach to the problem of electrocorrosion protection of passive structural metals is considered in this book, keeping the metals attacked by external currents in the boundaries of their passive field. The systems, developed in accordance with this approach, are based on the modification of existing and elaboration of new methods of electrocorrosion protection. These systems take into account corrosion and electrochemical characteristics of the aggressive media (redox potential, conductivity etc.) and of the passive metal (corrosion and activation potentials, current density in a passive state, etc) as well as the sizes and distribution character of the external currents.The book covers analysis of leakage current distributions in electrochemical plants, their influence, methods to estimate corrosion stability of metallic structures subject to external currents and presents many concrete examples of the successful introduction of corrosion protection systems in operating plants. - A new approach to protection from electrocorrosion, taking into account the passive state of the metal in aggressive media - Newly developed and modifications of well known methods of electrocorrosion protection are presented - Systematized data on electrocorrosion and protection of metals, especially in electrochemical plants, allow corrosion engineers, researchers and personnel maintaining the equipment of electrochemical plants to analyze the corrosion state of metallic equipment and prevent electrocorrosion
