630 パルス通電焼結法におけるパルスの効果(新技術開発レポート)
詳細
Investigation of an influence of pulse condition on heating rate and a model experiment for estimating interface temperature are done in order to investigate the effect of pulse current on sintering in pulsed current sintering. Using a graphite mold, the heating rate depends on energy by pulsed current, but it is independent of a pulse frequency. In the model experiment using Al ball, variation of the interface temperature with time depends on a pulse frequency. The temperature difference between an interface and an Al body in the case of frequency 2Hz to 100Hz changes similarly, and it is preserved for a long time in comparison with that in the case of DC current.
