摘要/Abstract

摘要： 用金相法观察和分析了用1Cr18Ni9Ti焊丝进行焊接的1Cr18Ni9Ti奥氏体不锈钢板和1Cr13马氏体不锈钢板焊接接头的组织;通过海水模拟溶液浸泡试验,测量焊接接头极化曲线和交流阻抗曲线,对比分析了焊缝与母材的耐腐蚀性能。结果表明,焊接接头组织为典型的柱状晶凝固组织;焊接接头中,马氏体母材和焊缝区容易受到腐蚀,而奥氏体母材不易受到腐蚀。

Abstract: The structure of welded junction of 1Cr18Ni9Ti austenite stainless steel plate and 1Crl3 martensite stain- less steel plate welding by 1Cr18Ni9Ti electrode has been observed and analyzed by metallographic method; and the polarization curves and alternating current impedance curves were measured by immersion test of simulation seawater solution to contrast and analyze the corrosion resistance of weld seam and parent metals. Results showed that the structure of weld junction was typical columnar solidified structure; in welded junction, the martensite parent metal and weld seam region were easy to be corroded, while the austenite parent metal was not easy to be corroded.
