た。However, with the conventional joining method, it is difficult to process a metal-ceramic composite material as a cast-in material, and furthermore, the thermal expansion of aluminum or an aluminum alloy is reduced by the metal-ceramic composite material. Because of the larger size, it shrinks greatly in the cooling process after assembling to form a gap at the joint, which causes rattling at the time of use and makes it impossible to fix it with high reliability.

A joining structure in which a dovetail-shaped concave portion of a cast-in material made of aluminum or an aluminum alloy and a dovetail-shaped convex portion of a metal-ceramic composite material are engaged and joined together. Achieved by structure. Further, the object of the present invention is to form an aluminum or aluminum alloy characterized by casting a molten metal made of a metal-ceramic composite material into an as-cast material made of aluminum or an aluminum alloy having a dovetail-shaped recess. This is also achieved by a method of joining a cast-in material with a metal-ceramic composite material.

い接合構造が得られるという効果がある。The reason why the insert made of aluminum or an aluminum alloy has a dovetail-shaped recess is that the thermal expansion of aluminum or an aluminum alloy is larger than that of a metal-ceramic composite material, so that the cooling process after the insert is inserted. The dovetail of the dovetail of the metal-ceramic composite material at the joint is firmly engaged with the dovetail of the dovetail groove of aluminum or aluminum alloy, so that there is no backlash during use and reliable joining. There is an effect that a structure can be obtained.
