ABSTRACT:
Joined ceramic and metal is characterized by ceramic and metal thermally joined through an intermediate layer. The intermediate layer is composed of 20-70% by weight of silver, 1-20% by weight of palladium, 10-60% by weight of nickel and 1-10% by weight of titanium. The joined ceramic and metal has sufficient joining strength both at normal temperature and at high temperature, because the joined ceramic and metal suffers little deterioration even at high temperature. Since the joined ceramic and metal has the characteristics of ceramic such as resistance to heat, corrosion and wear, it can be used for a structure operated at high temperature such as a gas turbine engine, a turbo charger rotor, a piston, a suction valve, and an exhaust valve.
