The invention discloses an Al-Mg-Zn-Cu aluminum alloy test piece as well as a preparation method and application thereof, and belongs to the technical field of aluminum alloys. The Al-Mg-Zn-Cu aluminum alloy test piece is obtained by depositing an Al-Mg-Zn-Cu aluminum alloy raw material on the surface of a base material in an electric arc fuse mode; the Al-Mg-Zn-Cu aluminum alloy comprises the following chemical components in percentage by weight: 5 to 6 percent of Zn, 2 to 3 percent of Mg, 1 to 2 percent of Cu, 0.1 to 0.3 percent of Cr, not more than 0.9 percent of impurity elements and the balance of Al. The aluminum alloy test piece has high hardness and wear resistance in the deposition direction, the whole test piece has high self-corrosion potential, low corrosion current density and high mechanical tensile property, and the aluminum alloy test piece can be used as a structural part in aerospace, traffic transportation, automobile manufacturing, military equipment or tool clamps.

    本发明公开了一种Al‑Mg‑Zn‑Cu铝合金试件及其制备方法与应用,属于铝合金技术领域。该Al‑Mg‑Zn‑Cu铝合金试件由Al‑Mg‑Zn‑Cu铝合金原料以电弧熔丝的方式沉积于基材表面而得;Al‑Mg‑Zn‑Cu铝合金原料的化学成分包括5‑6wt%的Zn、2‑3wt%的Mg、1‑2wt%的Cu、0.1‑0.3wt%的Cr以及不超过0.9wt%的杂质元素,余量为Al。该铝合金试件在沉积方向具有较高的硬度和耐磨性,且该试件整体具有较高的自腐蚀电位、较低的腐蚀电流密度以及较高的力学拉伸性能,可用作航空航天、交通运输、汽车制造、军事装备或工装夹具中的结构件。
