が現状である。For example, in the cylinder block of an internal combustion engine, when a liner made of steel or cast iron with good wear resistance is cast in an aluminum alloy cylinder block, it has been considered to perform this casting by die casting. Generally, when constructing a composite material by such casting, in order to form a composite phase, the two must be completely fused and an alloy layer of aluminum and iron must be formed on this fused surface. It is necessary to be present. However, with the conventional die-casting technology of aluminum alloys,
At present, no alloy layer is formed between the aluminum alloy and iron by fusion, and the conditions for a composite material are not satisfied.

This was done with the aim of obtaining a compound monthly yield with high strength and good heat conduction between the two.In order to achieve this purpose, in the present invention, iron is added to a part of the aluminum die-cast product. When casting the iron-based material, at least the surface of the cast-in side of the iron-based material is plated with Ni, Cu, etc., an aluminum base material is die-cast, and the aluminum base material and the iron-based material are fused at the interface. It is characterized by forming an alloy layer.

ものである。次に、本発明の詳細な説明する。That is, to explain the method of the present invention in more detail, first,
The surface of the iron-based material that is the cast-in base material is coated with a metal that has good fusion properties with the aluminum alloy, such as a plating metal such as Ni or Cu. After that, the ferrous material treated in this way is placed in a mold, and the molten aluminum alloy is cast as a die cast. During such casting, the molten aluminum alloy and the ferrous material are mixed into the plated layer. A diffusion reaction occurs through the process, and the two are completely fused to form an alloy layer.In this way, a composite material with high bonding strength and good heat conduction between the two is created. That's what you get. Next, the present invention will be explained in detail.
