- the sintering process becomes complicated and difficult, and the sintering temperature is as follows.
- the temperature must be such that the copper conductive terminal member is not deformed and lower than the melting point of the metal powder, which limits the sintering temperature of the carbon base material.
- the carbon material must be selected to be close to the sintering shrinkage rate of the metal powder, which limits the range of carbon material selection and limits the carbon characteristics.
- the iron powder is adhered to the surface of the carbon base material, and this is sintered at a temperature not lower than the diffusion temperature of the carbon and not higher than the melting temperature of the iron, so that the iron layer is integrally formed on the surface of the carbon base material.
