METHOD OF RELAXING RESIDUAL STRESS IN CERAMIC-METAL JOINT BODY, AND CERAMIC METAL JOINT BODY
To improve heat-cycle resistance of a joint body of a ceramic member and a metal member by reducing residual tensile stress in the vertical direction on the joint boundary of a ceramic member and a metal member.SOLUTION: At least either of a load of compression stress or local heating is applied to the surface of a ceramic member 2 in the vicinity of the joint boundary 11 of the ceramic member 2 and the lower end of the side face of a metal member 3 in a joint body constituted of the metal member 3 jointed to the surface of the ceramic member 2, to reduce vertical residual tensile stress on the joint boundary 11 in the vicinity of the joint boundary 11 of the ceramic member 2.SELECTED DRAWING: Figure 5
【課題】セラミックス部材と金属部材との接合体において、セラミックス部材の金属部材との接合境界に対して垂直方向の引張残留応力を低減させ、耐熱サイクル性を向上させる。【解決手段】セラミックス部材２の表面に金属部材３が接合された接合体において、セラミックス部材２と金属部材３の側面の下端との接合境界１１近傍におけるセラミックス部材２の表面に、圧縮応力の負荷または局所加熱のうち少なくとも一方を施し、セラミックス部材２の接合境界１１近傍の接合境界１１に対して垂直方向の引張残留応力を低減させる。【選択図】図５
