Introduction – Aluminum and aluminum alloys exhibit good corrosion resistance by virtue of a layer of aluminum oxide that forms on the surface. While aluminum is often not coated because of its good corrosion resistance properties, there are occasions when coatings are applied to provide added protection in given environments (e.g., when the pH is […]

Introduction Concrete is the most widely used building material worldwide because it has many unique properties that make it ideal for use in construction. Concrete is formable and is naturally resistant to UV, mold and insects. Concrete is noncombustible and is relatively inexpensive relative to other building materials. Why Coat Concrete? There are several reasons
Introduction Ironically, the demand for improved water quality has made the service environment of wastewater treatment facilities even more aggressive, requiring higher performance coatings for corrosion protection. Environmental regulations have restricted the heavy metal content and required pH control of water discharged to wastewater treatment facilities. Prior to the implementation of these regulations, the microbes

Unlike many industrial structures, ships often contain a variety of multi-layer coating systems on a single vessel, and even on the exterior hull itself, often including a complex sequence of anticorrosive layers followed by antifouling layers. This article focuses on the recoating of a ship’s exterior hull that resulted in catastrophic failure before the ship
