摘要(Abstract)：

通过中试轧制、电渣压力焊制备了Cu-P-Cr钢及其焊接接头,利用光学显微镜研究了电渣压力焊接接头的组织晶粒度,利用干湿交替实验机、SEM、EPMA、XRD研究了Cu-P-Cr钢及其焊接接头在1.0×10-2mol/L的Na HSO3溶液中的耐腐蚀性能、锈层元素分布及组成,分析了母材与焊接接头的耐腐蚀机理及其影响因素。研究结果表明:焊接接头与母材的腐蚀速率相比碳钢分别为64.6%与61.5%。焊接接头锈层中Cu、Cr元素的大量富集、α-Fe OOH相的转变是腐蚀性能优异的主要原因,而焊缝及熔合区形态各异的铁素体+珠光体+魏氏组织和晶粒尺寸不均等导致了锈层中Cu、Cr富集程度低于母材、腐蚀性能稍弱于母材。
