摘　　要：海水中含有大量的氯化物,在有氯离子存在的条件下不锈钢设备容易发生点蚀、缝隙腐蚀以及应力腐蚀等腐蚀形式,这几种腐蚀形式主要的腐蚀机理为闭塞电池腐蚀。通过对闭塞腐蚀电池机理及防护措施的整理和归纳,为不锈钢设备安装调试和防腐蚀维护提供了一定的理论依据,更好的为材料腐蚀防护工作服务。The sea water contained a large number of chloride, for chloride ion existing conditions, it was easy to occur pitting corrosion, crevice corrosion and stress corrosion cracking and so on, the main corrosion mechanism of these several corrosion forms was occluded corrosion cell. Based on occluded corrosion cell mechanism and corrosion protective measures, it had been collected and summed up, For stainless steel equipment installation commissioning and anti-corrosion maintenance provides certain theoretical basis, better worked for material corrosion protection service.
