クス−金属結合体が使用される。In order to improve the thermal efficiency of a diesel engine, the walls of the combustion chamber are made of ceramic, the inner wall of the exhaust pipe is made of ceramic to improve heat retention, or the combustion chamber of an internal combustion engine, such as the ceramic carrier of a monolith type catalytic converter, is made of ceramic.
Ceramic-metal composites are used in high-temperature areas such as exhaust systems, which combine ceramic sintered bodies with good heat resistance and heat insulation with metal members such as iron, stainless steel, and aluminum with excellent mechanical strength. Ru.
しかるに熱膨張係数の小さいセラミックスと熱膨張係数

を提供するものである。This invention provides for a ceramic-metal composite used under conditions of high heat and strong vibration by interposing a cushioning material mainly made of asbestos or graphite on the joint surface between the ceramic sintered body and the metal member. The object of the present invention is to provide a ceramic-metal bonded body with strong binding strength between the two and excellent vibration resistance and heat resistance durability.
