Since a brazing material containing 1 as a main component is used for joining, the melting point of the brazing material is 584 ° C. or lower, which is lower than the melting point of the JIS standard brazing material, and as a result, an aluminum member having a solidus temperature above this temperature.

Since the joining is performed using a brazing material containing as a main component, the melting point of the brazing material is 560 ° C. or lower, which is lower than the melting point of the JIS standard brazing material, and as a result, an aluminum member having a solidus temperature above this temperature ( The wettability is improved and high-strength bonding is possible with respect to the metal layer containing Al as a main component formed on the bonding surface of the cast material, the wrought material) or the ceramic member. Furthermore, the manufacturing method of the third and sixth means is Cu 26.0.
Since a brazing material containing 27.6% by weight and 4 to 6.5% by weight of Si and having Al as a main component is used for joining, the melting point of the brazing material is 540 ° C. or lower, which is lower than the melting point of the JIS standard brazing material. As a result, the wettability is improved with respect to the metal layer containing Al as a main component formed on the joint surface of the aluminum member (cast material, wrought material) or ceramic member having a solidus temperature higher than this temperature, and the high strength is obtained.

When at least one selected from the group consisting of n and Ti is contained, effects such as lowering of melting point of brazing material, improvement of wettability, acceleration of age hardening and the like can be obtained, and joint strength can be improved. Further, by forming the metal layer containing Al 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 Al as the main component being 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, when the thickness of the “metal layer containing Al as a main component” is thinner than 0.08 μm, the bonding strength is low, but when it is 0.08 μm or more, a high-strength bonded body can be obtained. It is because the metal layer containing Al 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 Al as a main component, which exceeds 5 μm, because it increases the manufacturing cost of the bonded body. Further, even if the metal layer containing Al as a main component alone has a high adhesion strength to the ceramic member,
The adhesion strength between the ceramic member and the metal layer containing Al as a main component is improved by interposing one or more intermediate metal layers having good reactivity with the ceramic member between the metal layer containing Al as a main component and the ceramic member. As a result, the joint strength is increased. For example, Ti layer, Zr layer, Mo
It is preferable to interpose one or more as an intermediate metal layer such as + Mn layer.

The bonded body was obtained by holding it for 0 minutes to carry out bonding. After joining
A tensile test piece was subjected to a finishing test in accordance with JIS No. 4 test piece. Table 2 shows the results. As shown in Table 2, the bonded body obtained by the manufacturing method of the present invention had high bonding strength. Specifically, the aluminum member 2 at the joint interface was deformed first, and then the interface between the aluminum member 2 and the ceramic member 1 was fractured. The fracture surface is the aluminum member 2 on the fracture surface of the ceramic member 1.
Has become attached. The joint strength of the brazing material was equivalent to that of the aluminum member 2 or the ceramic member 1 itself. On the other hand, in the joined body produced by the manufacturing method of the comparative example, the joining strength was low because it was not joined or was the starting point and the progress of fracture was in the joined interface or in the brazing filler metal 3 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.
