Book Description

This synthesis will be of interest to bridge designers, materials engineers, maintenance engineers, and others concerned with coating systems used to protect bridge steel from corrosion. Information is presented on the causes of steel corrosion and the types of surface preparation and coatings used to protect the steel. Steel bridges need some type of protective coating to keep them from corroding. This report of the Transportation Research Board explains the mechanisms of steel corrosion and how coatings protect the steel, discusses the need for and types of surface preparation, and describes twenty types of available coating systems under three general categories: inhibitive systems, zinc-rich (sacrificial) systems, and barrier systems.

Book Description

This synthesis will be of interest to state department of transportation (DOT) bridge maintenance engineers, coating specialists, chemists, and researchers. Manufacturers and suppliers of corrosion protection products and systems for exposed structural steel on existing bridges will also find it of interest. This synthesis describes current practice regarding maintenance and protection strategies for exposed structural steel on existing bridges. NCHRP Synthesis 251, Lead-Based Paint Removal for Steel Highway Bridges ( 1997), provides a complementary and more in-depth treatment of maintenance issues involving lead-based paint removal. This report of the Transportation Research Board defines the maintenance management systems and decision making criteria used by transportation agencies for maintaining exposed bridge steel. Material selection criteria, surface preparation and application practices, quality control and quality assurance programs, and funding mechanisms are discussed in detail. The impact of recent and proposed environmental and worker protection regulations on current practice is reported. Information for the synthesis was collected by surveying state transportation agencies and by conducting a literature search. Responses to the survey, Appendix C to this document, are published on the Internet as NCHRP Web Document 11.

Book Description

A current state-of-the-art survey is presented with regard to painting of highway structural steel. A thorough literature review was conducted and an inspection and evaluation made of more than 4,000 paint exposure tests. Paint film thickness measurement studies were made. Specific recommendations are given for selecting typical paint systems on the basis of six environmental zones, which represent the range of severity of environment in which highway steel structures are located in the United States. Model specifications are suggested for surface preparation, application, material procurement, and paint system.

Book Description

This synthesis will be of interest to bridge painting contractors, bridge maintenance and construction engineers, environmental engineers, equipment manufacturers and suppliers, and others interested in bridge paint removal. Information is provided on current practices in bridge paint removal, containment, and disposal, with special attention paid to environmental, health, and cost issues, along with a discussion of current environmental regulations governing paint removal practices. The removal of bridge paint is a nationwide problem with sensitive environmental concerns and rapid changes in available technology and regulatory oversight. This report of the Transportation Research Board describes the current state of the practice for bridge paint removal, containment, and disposal, especially with regard to lead-based or other toxic paints. Additionally, current environmental regulations and health concerns in this area are examined.

Book Description

Smart Protective Coatings for Corrosion Control Overview of the latest research in advanced coatings for anticorrosion and the development of optimized surfaces with high anticorrosion ability Smart Protective Coatings for Corrosion Control introduces the newest research developments in self-healing coatings, self-reporting coatings, and superhydrophobic coatings, reviewing corrosion processes and strategies, smart coatings for corrosion protection, techniques for synthesizing and applying smart coatings, different kinds of self-healing and self-reporting coatings activated by different environmental stimuli, and current and future trends of protective coatings for automotive, aerospace, marine, nuclear, oil/gas, and military applications. This book also discusses new ideas in the field, such as the combination of self-healing and self-reporting properties, new techniques to study localized microscale electrochemical corrosion behavior, as well as atmospheric corrosion monitor technique to study the real-time protection behavior of coatings in different environments. The processes of coating degradation and metal corrosion are discussed in detail so that non-experts can gain a basic understanding of the corrosion protection techniques. Written by two highly qualified academics with significant research experience in the field, Smart Protective Coatings for Corrosion Control includes information on: Coating preparation, filler preparation, surface characterization, macroscopic and microscopic electrochemical properties, and self-healing performance of self-healing coating systems under different environmental stimuli Photothermal conversion species such as graphene oxide, titanium nitride, and Fe3O4 Different types of corrosion indicators, such as phenolphthalein, sulfosalicylic acid-modified carbon dots, and phenanthroline High-mobility polymer networks that endow a shape memory effect and allow coatings to recover their original shape and barrier properties Solutions to three corrosion conditions—room temperature immersion, alternating wet-dry, and outdoor atmospheric exposure conditions Presenting the latest research in the field, Smart Protective Coatings for Corrosion Control is a practical and highly valuable reference on the subject for scientists, researchers, and students in diverse programs of study.

Book Description

The operation of numerous components that are critical to safety in industries around the world relies on protective coatings. These coatings often allow process equipment to serve a purpose in environments well beyond the operational limit of the uncoated components. Durability, ease of application, repairability, reliability and long-term performance of such coatings are all key to their application. Therefore, this book, Coatings for Harsh Environments, is devoted to research and review articles on the metallic, non-metallic and composite coatings used in aggressive environments. In particular, the topics of interest include, but are not limited to: coatings for high temperature and molten salt applications; thermal spray and cold spray coatings for aggressive environments; corrosion, wear and cavitation resistant coatings; coatings for mitigating marine corrosion; coatings for chemical and petrochemical plants; thermal barrier coatings.

Book Description

This book covers a broad range of materials science that has been brought to bear on providing solutions to the challenges of developing self-healing and protective coatings for a range of metals. The book has a strong emphasis on characterisation techniques, particularly new techniques that are beginning to be used in the coatings area. It features many contributions written by experts from various industrial sectors which examine the needs of the sectors and the state of the art. The development of self-healing and protective coatings has been an expanding field in recent years and applies a lot of new knowledge gained from other fields as well as other areas of materials science to the development of coatings. It has borrowed from fields such as the food and pharmaceutical industries who have used, polymer techniques, sol-gel science and colloidosome technology for a range encapsulation techniques. It has also borrowed from fields like hydrogen storage such as from the development of hierarchical and other materials based on organic templating as “nanocontainers” for the delivery of inhibitors. In materials science, recent developments in high throughput and other characterisation techniques, such as those available from synchrotrons, are being increasing used for novel characterisation – one only needs to look at the application of these techniques in self healing polymers to gauge wealth of new information that has been gained from these techniques. This work is largely driven by the need to replace environmental pollutants and hazardous chemicals that represent risk to humans such as chromate inhibitors which are still used in some applications.
