    • The invention relates to a metal cast component (1), which is intended in particular for parts of internal combustion engines or piston compressors, such as pistons, gearboxes, crankcases and other housings and/or cylinder heads, wherein the cast component (1) consists at least in certain portions of an iron aluminide and/or is a composite cast component comprising at least two portions (2, 3), which consist of a cast iron and/or an iron aluminide and/or a light metal. The invention also relates to a method for producing a metal cast component (1), in particular for parts of internal combustion engines or piston compressors, such as pistons, gearboxes, crankcases and other housings and/or cylinder heads, which consists of one or more cast materials such as cast iron and/or iron aluminide and/or light metal, in which method a first portion (2) of the cast component (1) is produced in a first casting operation and a further portion (3) of the cast component (1) is produced in a further casting operation and a coating, in particular of iron aluminide and/or a nickel alloy, is applied as a coupling agent layer to the first portion (2) before the further casting operation.
    • 本发明涉及一种金属铸造部件(1),其特别用于内燃机或活塞式压缩机的部件,例如活塞,变速箱,曲轴箱和其它壳体和/或气缸盖,其中铸件(1) 至少在铁铝化物的某些部分中和/或是包含由铸铁和/或铁铝化物和/或轻金属组成的至少两个部分(2,3)的复合铸造部件。 本发明还涉及一种用于生产金属铸件(1)的方法,特别是用于内燃机或活塞式压缩机的部件,例如活塞,齿轮箱,曲轴箱和其它壳体和/或气缸盖,其由一个或多个 更多的铸造材料,例如铸铁和/或铁铝化物和/或轻金属,其中铸造组分(1)的第一部分(2)在第一铸造操作中制备,并且其中另一部分(3) 在另外的铸造操作中制造铸造组分(1),并且在进一步的铸造操作之前,将涂覆,特别是铁铝化物和/或镍合金的涂层作为偶联剂层施加到第一部分(2)。
