“缓”然一新——深蓝里的金属防腐

The Metal Protection in Ocean Engineering

缓蚀剂和缓蚀涂层能够在金属表面形成一层致密保护膜,从而达到延缓金属腐蚀的目的。其具有成本低、可操作性强、缓蚀效果好、寿命长等优点,成为海洋工程防腐中一类重要的材料。围绕海洋工程中钻井平台、风力发电机、航空母舰和核潜艇等中易发生腐蚀的部位介绍化学缓蚀剂及缓蚀涂层的结构、性质,并突出其重要作用。

The corrosion inhibitor and anti-corrosion coating can form dense film on the surface of metal under some specific environments to achieve the purpose of protecting metal.Since such chemical corrosion inhibitors and coatings have the advantages of low cost,strong operability,good corrosion inhibition effect,and long durability,they have become one of the most important anti-corrosion strategies in ocean engineering.This paper will introduce the structure of chemical corrosion inhibitor and anti-corrosion coatings in the applications of oil wells,wind turbine,aircraft carrier and submarine where are prone to corrosion,as well highlight its importance.
