点があった。2. Description of the Related Art Carbon materials are brittle and inferior in oxidation resistance, but on the other hand, they have an excellent characteristic that they are hard to be wetted by molten metal, and by utilizing these characteristics, they are used for molten metal parts and welding members. These members are usually formed by cutting out the entire member from a large block, or a part of the member is formed of carbon, and the carbon member is mechanically attached to the main body of the member such as screws or caulking. It is used by integrating with various joining means. However, if the whole is made of carbon, the cost is high and it is often damaged during use due to its brittleness.In addition, if it is mechanically integrated with the metal body, the screws and caulks will become loose. There was a drawback that it was easy to fall off.

労性の改善が強く要望されるのである。Therefore, in order to improve these drawbacks, it is effective to limit the carbon to only the necessary part and form the main body part with a metal material and to join the two metallurgically. Needs to solve the following problems. (1) Problem of thermal stress at the joint Since originally carbon and metal have extremely different expansion coefficients,
Large thermal stress is generated in the joint, and the joint is easily broken. (2) Problem of thermal fatigue Carbon-metal bonded bodies usually reach a maximum ambient temperature of 450 ° C, and the normal temperature is 450 ° C.
Because it is repeatedly heated up to, fatigue occurs and it cannot be used for a long time. However, conventionally, there is no bonded body of a carbon-based material and a metal that solves such problems, and there is a strong demand for improvement in heat resistance and heat fatigue resistance.
