Contains papers presented at a November 2000 symposium, examining laboratory evaluation methods, test methods, and model prediction in research on atmospheric corrosion, corrosion of rebar in concrete, marine corrosion, and other related corrosion phenomena. Topics include degradation of fiber reinf

Engineers with an interest in the marine environment can take advantage of many years of accumulated corrosion experience in a quick and concise manner with this publication. It covers the corrosion behavior in sea water of steel, stainless steel and cast iron as well as alloys of copper, aluminum, nickel and titanium. Applications, commonly-used alloy compositions and mechanical properties are also covered for each alloy system, plus a special section is devoted to galvanic corrosion and its avoidance.

This issue of ECS Transactions, ¿Corrosion in Marine and Saltwater Environments 3¿, is the continuation of successful symposia held in 1999 and 2004, hosted by The Electrochemical Society. The papers in this issue were presented at the 2008 PRiME meeting held in Honolulu, Hawaii, from October 12 to 17, 2008. The goal of this symposium was to address a wide spectrum of corrosion research in marine and other saltwater environments and to provide a forum to examine the most recent ideas and advances in the understanding of corrosion processes, mechanisms, and means of corrosion prevention or control from both a basic and applied research approach.

Atmospheric corrosion in México is creating significant structural problems in the tropical marine regions of the Gulf of México. This is especially true along the southern Gulf coast where increasing petrochemical pollution is present with the extremely high chloride concentrations resulting from strong onshore winds, and the ever-present high time-of-wetness. The climatic and environmental parameters have been measured, between 1993 and 1998, at 12 coupon exposure sites at marine locations around the Gulf of México. Corrosion classifications for iron, aluminum, copper and zinc have been calculated for each site using mean values of the time-of-wetness, chloride and sulfur dioxide concentrations. The theoretically predicted corrosion rates have been determined from the site classification data, and compared to the 12-month corrosion rates measured by coupon mass loss for the four metals exposed at the same sites. The data show that all sites have at least a C4 classification with most having C5 even though many are located over 1 km from the shoreline. The measured corrosion rates of different metals are often not in good agreement with those predicted using the environmental parameters, providing evidence that other climatic factors such as frequency of precipitation can modify the corrosion rates and distort the correlation with theoretical corrosion predictions and models. Spectroscopic analysis of corrosion products from exposed carbon steel coupons shows that large fractions of akaganeite form in high chloride environments, along with lepidocrocite and goethite. The oxides form in distinct layers on the steel surface. The amount of akaganeite formed is related to some extent by the precipitation frequency which controls if pollutants are regularly flushed from the steel surfaces.

The diversity of subjects involved in marine corrosion and fouling processes are evident in the approaches and techniques described in this book. An improvized understanding of biologically influenced corrosion and fouling processes is essential to the development of better corrosion protection systems, and this book shows new perspectives in our appreciation of these subjects. Equally, powerful microscope imaging, surface spectroscopy and electrochemical techniques have become available and are providing new information on metal surfaces experiencing fouling or microbial corrosion. Examples include confocal laser microscopy, scanning probe microscopy, Fourier Transform infrared spectroscopy, scanning electrochemical microscopy and scanning (or vibrating) reference electrode techniques. Advances in knowledge of biocorrosion processes have enabled improvements in corrosion monitoring and protection strategies. Examples include metal or polymer coatings and the use of corrosion inhibitors and biocides. This book aims to provide a contribution to existing literature on biocorrosion in the marine environment.
