なる。When the brazing material composition contains Zn at a content of 18 atomic% or less, the melting point of the brazing material is further lowered, and a wide range of aluminum member types can be selected as the joining member. However, if the amount of Zn added exceeds 18 atomic%, the bondability is adversely affected and the joint strength is reduced. Further, by forming the metal layer containing Ni as a main component on the surface of the ceramic member, the wetting property between the surface of the ceramic member and the brazing material is improved, and the bonding strength with the aluminum member can be increased. Further, by forming a plurality of layers with the metal layer containing Ni as the uppermost layer on the surface of the ceramic member, the wetting property between the surface of the ceramic member and the brazing material is improved and the bonding strength with the aluminum member is improved. Can be increased. Further, the thickness of the “metal layer containing Ni as a main component” is 0.
When the thickness is less than 08 μm, the bonding strength is low, but 0.08
When the thickness is at least μm, a high-strength joined body can be obtained. It is because the metal layer containing Ni as a main component increases the wetting property between the surface of the ceramic member and the brazing material at the time of joining. However, it is not preferable to extremely thicken the metal layer containing Ni as the main component so as to exceed 5 μm since this increases the manufacturing cost of the bonded body. Further, by interposing one or more intermediate metal layers having good reactivity with the ceramic member between the metal layer containing Ni as a main component and the ceramic member, the ceramic member and the metal layer containing Ni as a main component are adhered to each other. This will improve the strength and thus the bonding strength.

It had high strength. As for a specific fracture mode, first, the aluminum member 2 was deformed, and then the aluminum member 2 was fractured. As a result, the aluminum member 2 was attached to the fracture surface of the ceramic member 1. The joint strength of the brazing material was similar to that of the aluminum member 2 itself. On the other hand, the bonded bodies (No. 35, 36, 47, 48) manufactured by the manufacturing method of the comparative example are
The joint strength was low because the joint was not joined or was the starting point, and the progress of fracture was in the joint interface or in the three brazing filler metal layers.

となる。EFFECTS OF THE INVENTION By using the manufacturing method according to the present invention, it is possible to join a cast aluminum material having a low melting point and difficult to braze to a ceramics member. Therefore, the aluminum member as the joining member can be selected in a very wide range including the wrought material, and a high-strength joined body of the ceramic member and the aluminum member can be obtained.
