    摘要:

    實際生產(chǎn)過程中，補(bǔ)焊過程往往焊接接頭的可靠性產(chǎn)生影響。本文研究了補(bǔ)焊對7N01-T5/7N01-T4異種鋁合金腐蝕性能的影響。結(jié)果表明，補(bǔ)焊會導(dǎo)致焊接接頭耐蝕性降低，特別是熱影響區(qū)域。焊接接頭腐蝕性能演變主要與補(bǔ)焊過程中Zn元素從基體向晶界處的擴(kuò)散有關(guān)。

    Abstract:

    Mandatory repair welding for production of structural parts easily causes problems to the reliability of welded joints due to the resultant extra thermal cycle. The evolution of corrosion resistance of repair welded joint between 7N01 aluminum alloy in T5 and T4 state by metal inert gas welding process was investigated. The results reveal that repair welding deteriorated the corrosion resistance of weldment, especially of the heat-affected zone. The main reason for the change in corrosion resistance of repair weldment could be related to the transformation of precipitates and diffusion of Zn from the matrix to grain boundaries caused by the extra thermal cycles.
