摘要： In a composite casting process for making aluminum alloy components for internal combustion engines, which components are provided at highly loaded surfaces with shaped elements which consist of fibers or whiskers and are bonded to the castings, the shaped elements consisting of fibers of whiskers are infiltrated with an aluminum alloy which has a higher melting point than the aluminum alloy of the casting. The infiltration is effected in such a manner that the infiltrated aluminum alloy forms a cover layer on the shaped element. In order to ensure the formation of a bond between the casting and the shaped element as the aluminum alloy for making the casting is cast in contact with the shaped element, the infiltrated shaped elements are dipped into a molten solder alloy before the aluminum alloy for making the casting is cast in contact with the shaped element, and the latter is subsequently placed into the heated mold for making the casting, whereafter the casting is made.
