Claims
- 1. A method of bonding a member made of alumina to another member made of a metal, comprising the steps of:
- providing a sheet containing aluminum;
- interposing said sheet between said alumina member and said metal member so that the surface of the sheet is in contact with respect to the surfaces of the alumina member and the metal member; and
- keeping said sheet and the respective surfaces of said members in contact while heating to a temperature higher than the solidus line of said aluminum containing sheet and applying pressure to interfaces defined between said sheet and said members during said heating, wherein said sheet is a three-layer material having an aluminum containing core and two skins, each skin comprising an aluminum and silicon based alloy.
- 2. A method according to claim 1, wherein said core is composed of pure aluminum.
- 3. A method according to claim 1, wherein said core is composed of an aluminum based alloy.
- 4. A method according to claim 1, wheren the pressure applied to the interfaces is in such degree that the core is protruded from the outer periphery of said interface.
- 5. A method according to claim 1, wherein said another member is made of a metal selected from the group consisting of iron, steel and aluminum.
- 6. A method according to claim 1, wherein said said temperature is less than or equal to 660.degree. C.
- 7. A method according to claim 1, wherein said temperature is in the range of from 580.degree. C. to 610.degree. C.
- 8. A method according to claim 1, wherein said pressure is in the range of from 0.2 to 2.0 Kgf/mm.sup.2.
