Abstract: The present invention provides an assembly of an aluminum-based element and an element made of steel provided on at least one of the surfaces thereof with a metal coating. The metal coating is made of a zinc-aluminum-magnesium alloy including from 2.3% to 3.3% by weight of magnesium and from 3.5% to 3.9% by weight of aluminum. The remainder of the metal coating is zinc, inevitable impurities and possibly one or more additional elements selected from among Si, Sb, Pb, Ti, Ca, Mn, Sn, La, Ce, Cr, Ni or Bi. The coated surface of the steel element is in at least partial contact with the the aluminum-based element. The contact is brought about by a layer of adhesive or sealant having a thickness of less than 5 mm. The present invention also provides a part for a vehicle including at least one assembly and a vehicle.

Abstract translation: 本发明提供一种铝基元件和由至少一个表面上设置有金属涂层的由钢构成的元件的组件。 该金属涂层由包含2.3％至3.3％重量的镁和3.5％至3.9％重量的铝的锌 - 铝 - 镁合金制成。 金属涂层的其余部分是锌，不可避免的杂质以及可能的一种或多种选自Si，Sb，Pb，Ti，Ca，Mn，Sn，La，Ce，Cr，Ni或Bi中的另外的元素。 钢元件的涂覆表面与铝基元件至少部分接触。 接触是由厚度小于5mm的粘合剂或密封剂层引起的。 本发明还提供了一种包括至少一个组件和车辆的车辆的部件。
