Abstract

Publisher Summary This chapter mentions that copper, aluminum, and titanium alloys are the most important of the alloys belonging to the group of non-ferrous metals generally used in marine engineering. The chapter focuses on the corrosion behavior of copper and aluminum alloys. Copper alloys are mainly used for pipelines, heat exchangers, screw propellers, valves, gate valves, clad plates for steel hulls of small ships, clad plates for drilling rigs' splash zones, etc. Aluminum alloys are used for hulls of fast ships and superstructures of other ships to improve their stability, for construction of Liquefied Natural Gas (LNG) cargo tanks and also for construction of yachts, sport boats, police boats, etc. The chapter considers aluminum and tin brasses, cupro–nickels 90/10 and 70/30, aluminum–nickel, tin, and silicon bronzes, as well as the Al–Mg and Al–Mg–Zn aluminum alloys. It discusses several kinds of corrosion and the main causes of their occurrence and presents the problems of modeling corrosion processes on aluminum and copper alloys and to the long-term prediction of life for these alloys.
