性の良い金属で表面を被覆することにより耐食性の良い
応力緩和を有したセラミックスの接合方法を提供する。By focusing on the low Young's modulus of copper or nickel, we reduce the stress that occurs during bonding, and by coating the surface with highly corrosion-resistant metals such as gold, platinum, and palladium, we are able to bond ceramics that have good corrosion resistance and stress relaxation. provide a method.

緩和材を有する接合方法を提供することを目的としてい
る。In the conventional joining method, as shown in Fig. 2, the stress relaxation material 8 that joins the zirconia 4 and the metal 5 is copper or nickel, and because it is directly exposed on the surface, the environmental resistance (mainly It has poor corrosion resistance (corrosion resistance) and has the disadvantage of spoiling the aesthetic appearance of decorative items. Further, when gold is used as a stress relaxation material, although the environmental resistance is good, the cost of the joint becomes extremely high, so it is not practical. Therefore, in order to solve these conventional drawbacks, the present invention aims to provide a joining method that has good corrosion resistance and uses an inexpensive stress relaxation material.

す。(Example 1) Figure 1 (al shows the cross section of the stress relaxation material before brazing of the present invention. 1 is a core material, 2 is a coating material (gold, platinum, palladium, and its alloy), and the coating material is applied in the range of 1 to 5μ. Figure 1+bl shows a cross section of the joint according to the present invention. 3 is an alloy of the core material 1 and the covering material 2, 4 is zirconia, and 5 is stainless steel (e.g. , 5US304), 6 is a brazing material layer mainly composed of gold and containing active metals such as titanium.Here, the coating material 2 is set to 1 to 5μ, but if it is less than 1μ, it will diffuse too much during brazing and cause stress. This is because the corrosion resistance of the relaxation material cannot be maintained, and the reason why the upper limit was set at 5μ is because the alloy metal due to diffusion during brazing becomes thick and the stress relaxation effect is significantly reduced. Indicates joint quality.
