摘　　要：研究了4种常用海水管系材料和HDR双相不锈钢在静止天然海水中的自腐蚀情况,进行了极化曲线测试,并将4种常用海水管系材料分别和HDR双相不锈钢进行了电偶腐蚀试验。结果表明,HDR双相不锈钢具有很好的耐海水腐蚀性能;在常用海水管系材料和HDR双相不锈钢的电偶腐蚀试验中,HDR双相不锈钢作为阴极受到保护,与其偶合的材料腐蚀速度明显加快。Corrosion properties of four marine pipe materials and HDR duplex stainless steel in still natural seawater were studied.Polarization curves of these materials were plot.Galvanic tests of the four marine pipe materials with HDR duplex stainless steel were carried out.The results showed that HDR duplex stainless steel excellent marine corrosion resistance and were protected as cathode in galvanic test by the other marine pipe materials whose corrosion rate was accelerated obviously.
