PURPOSE:To efficiently manufacture a joining body without lowering of characteristics and deformation for materials due to joining by radiating laser beam on a ceramics surface so as to deposit the metallic element of a ceramics component on its irradiated part, and joining metallic materials together through this metallic layer. CONSTITUTION:Argon gas is led to flow into a vacuum container after both joining samples 7, 8 are mounted into a joining jig 9 in the vacuum container 1 having an exhaust system 2 to keep its inside under vacuum and the degree of vacuum in the vacuum container is set by exhaust to approximately 5X10<-6>Torr with the exhaust system 2. A laser beam 3 is radiated on the joining sample 7 through a condensing lens 4 so as to deposit the metallic element of a ceramics component on the irradiated part after argon gas is ionized by an ion beam generator 5 and radiated on both joining samples 7, 8. Next, the joining samples 7, 8 are brought in contact with each other and pressurized by the joining jig 9, and heated at a low temperature by irradiation of the ion beam 6. By this process, the joining body for ceramics having the strong joining strength and metallic materials can be formed at a low temperature. |
