Conversion coatings and primers used for the corrosion protection of aluminum alloy components in aircraft are based, almost exclusively, on chromate systems that are on the Environmental Protection Agency List of hazardous materials. Chromium is targeted for elimination from the workplace. This effort is part of a research program to develop a suitable replacement for chrome in coatings technology. This effort focused on the use of cerium chemistry to provide the corrosion inhibition for aluminum alloys used in the aircraft industry. The primary tasks were the development of a non-chromated conversion coating and surface treatment and a non-chromated primer coating system for military aircraft. This report presents the development, characterization, and evaluation of inorganic coatings that can serve as potential replacements for current chromate coatings. This effort was performed by the Materials Research Center at the University of Missouri-Rolla and the Boeing Corporation.

The Air Force requires the development of an environmentally compliant chromate-free aircraft coating system that meets or exceeds current corrosion protection capabilities. A number of non-chromated pretreatments and primers have been independently developed over the past years. This report compares the corrosion resistance performance of selected fully non-chromate systems to the standard chromate containing coating system. The data identified two non-chromated systems that performed comparably to the standard chromated aircraft coating system.

A smart coating is defined as one that changes its properties in response to an environmental stimulus. The Handbook of Smart Coatings for Materials Protection reviews the new generation of smart coatings for corrosion and other types of material protection. Part one explores the fundamentals of smart coatings for materials protection including types, materials, design, and processing. Chapters review corrosion processes and strategies for prevention; smart coatings for corrosion protection; techniques for synthesizing and applying smart coatings; multi-functional, self-healing coatings; and current and future trends of protective coatings for automotive, aerospace, and military applications. Chapters in part two focus on smart coatings with self-healing properties for corrosion protection, including self-healing anticorrosion coatings for structural and petrochemical engineering applications; smart self-healing coatings for corrosion protection of aluminum alloys, magnesium alloys and steel; smart nanocoatings for corrosion detection and control; and recent advances in polyaniline-based organic coatings for corrosion protection. Chapters in part three move on to highlight other types of smart coatings, including smart self-cleaning coatings for corrosion protection; smart polymer nanocomposite water- and oil-repellent coatings for aluminum; UV-curable organic polymer coatings for corrosion protection of steel; smart epoxy coatings for early detection of corrosion in steel and aluminum; and structural ceramics with self-healing properties. The Handbook of Smart Coatings for Materials Protection is a valuable reference for those concerned with preventing corrosion, particularly of metals, professionals working within the surface coating industries, as well as all those with an academic research interest in the field. Reviews the new generation of smart coatings for corrosion and other types of material protection Explores the fundamentals of smart coatings for materials protection including types, materials, design, and processing Includes a focus on smart coatings with self-healing properties for corrosion protection

The Environmental Protection Agency (EPA) in the US has imposed legislations on the use of hexavalent chromium and solvents contributing to emission of volatile organic compounds in primer coatings. This has led researchers to pursue development of alternative environmentally-friendly coatings which would eliminate chromate conversion coatings (CCC). This thesis discusses the work done towards the development of a novel, chromate-free, low-VOC, water-based, organic coating system for corrosion protection of AA 2024-T3 aerospace alloy. These special coatings which can be applied directly to the metal are termed as 'superprimers' and consist of novolac epoxy binder, silanes, polyurethane and non-chromate inhibitors. Coating evaluation tests were employed to compare the performance of the superprimer coatings with controls. SEM, FTIR and NMR were carried out to understand the chemistry of the coatings. The requirement for a conversion coating was obviated and the coating system developed was on par with the chromate-based control coating in terms of performance.

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.

This proceedings book presents the main findings of the 13th International Seminar on Polymer Science and Technology ( ISPST 2018), which was held at Amirkabir University of Technology, Tehran, on November 10–22, 2018. This forum was the culmination of more than three decades of academic and industrial activities of Iranian scholars and professionals, and the participation of many notable international scientists, in covering various important polymer-related subjects of concern to Iran and the world at large, including polymer synthesis, processing and properties, as well as issues concerning polymer degradation, stability, and environmental aspects. For the past half a century, the growing concern for advancing human health, quality of life, and – especially in the last few decades – avoiding and combating environmental pollution have shaped and driven scientific activities geared toward the creation of smart materials that are compatible with the human body, and have prompted scientists and technologists to pursue research using natural and sustainable sources. This book highlights efforts to responsibly address the problems caused by, and which can potentially be solved by, polymers and plastics.
