A LAN Brown of Arc Energy Resources discusses the benefits of weld overlay cladding to protect marine equipment and components from corrosion; and reviews the options available using corrosion-resistant alloys. PAINTS AND coatings are readily available to protect surfaces on a ship's superstructure from saltwater in the atmosphere, but the problem remains for marine engineers ensuring the long-term integrity of mechanical and piping equipment against aggressive corrosion caused by the sea itself, either below the surface or in areas subjected to significant amounts of saltwater spray. In order to maintain the efficient and reliable operation of marine equipment, the ship's engineer needs to know what techniques are available to extend the life of new plant or refurbish worn or corroded components and, just as important, what the cost benefits are compared to the use of expensive base materials or replacing the part.
