| 摘 要： | 通过测定H65铜合金搅拌摩擦焊接头和手工电弧焊接头在3.5%NaCl溶液中的开路电位和极化曲线,研究其电化学腐蚀性能。结果表明,搅拌摩擦焊接头的抗腐蚀性能优于手工电弧焊接头。搅拌摩擦焊接头微观组织的细化、均匀化和致密化降低了晶界和晶粒在电化学上的不均匀性。手工电弧焊接头脱锌层和基体界面处产生的拉应力对抗腐蚀性能有较大影响。

| Abstract: | The electrochemical corrosion properties of welded joints of H65 brass alloy by friction stir welding and manual arc welding were studied by measuring open potentials and polarization curves in 3.5% NaCl solution. The result shows that the corrosion resistance of the friction stir welded joint is better than that of manual arc welded joint, because microstructural refinement, homogenization and densification reduced the electrochemical heterogeneity of grains and grain boundaries. The tensile stress between the dezincification layer and substrate has great effect on the corrosion resistance of the manual arc welded joint |
