摘要：

Recently, higher grade materials have been used for seawater pumps. However, it is desirable that more economical materials, e. g. , cast iron, carbon steel, and type 316 stainless steel, are properly used for their services. This paper proposes the practical protection methods from seawater corrosion, i. e. , (a) differential aeration cell corrosion (caused by the flow rate difference), (b) galvanic corrosion (caused by the use of two different materials), (c) crevice corrosion and others, which frequently occur in seawater pumps, and describes the applicability of these measures based on the actual application of seawater pumps.
