Abstract: The invention provides a structure having a porous metal body firmly attached to a solid metal carrier as in figure 1. This composite structure is built up from a porous body (10) which is at least partially made of aluminium or an aluminium alloy and a solid metal carrier (20) made of aluminium or an aluminium alloy. There is also a formed in situ layer (30) obtainable by thermal spraying. This layer is bonded directly to at least a portion of said solid metal carrier material (20) and the porous body (10) is sintered to said layer (30) which is bonded to the solid metal carrier. Further, the present invention provides a method for firmly attaching a porous metal body to a solid metal carrier and the use of those structures in heat exchangers, electronic assemblies and heat sinks. More specifically, the invention provides a firmly bonded aluminium construction containing porous aluminium material and a solid aluminium carrier.

Abstract translation: 本发明提供一种结构，其具有牢固地附接到如图1所示的固体金属载体的多孔金属体。该复合结构由至少部分地由铝或铝合金制成的多孔体（10）和固体 由铝或铝合金制成的金属载体（20）。 还可以通过热喷涂获得形成的原位层（30）。 该层直接粘合到所述固体金属载体材料（20）的至少一部分上，多孔体（10）被烧结到与固体金属载体结合的所述层（30）上。 此外，本发明提供了一种用于将多孔金属体牢固地附接到固体金属载体的方法以及这些结构在热交换器，电子组件和散热器中的使用。 更具体地，本发明提供了一种牢固结合的铝结构，其包含多孔铝材料和固体铝载体。
