Abstract
The invention relates to a method for attaching a first body which is of one of a metal matrix composite (MMC)-material or copper to a second body which is a ceramic member for acting as a heat sink, wherein the surface of the ceramic member which is placed against the MMC- or copper body is coated with a first metal by heating the two bodies to above the eutectic temperature of a system comprised of the matrix metal of the MMC-body or the copper of the copper body and the first metal applied to the surface of the ceramic member; and subsequently cooling the system to room temperature.
Claims25
A method for attaching a metal matrix composite (MMC) body to a ceramic member, comprising the steps of:
- coating a first metal on a surface of the ceramic member;
- placing the ceramic member with the metal-coated surface upon the MMC body;
- heating the MMC body and the ceramic member to a temperature above an eutectic temperature of the eutectic system defined by the matrix metal of the MMC-body and the first metal applied on the surface of the ceramic member;
- and
- cooling the system to room temperature.
