内容記述 | Electrochemical charging of hydrogen for 99.6% and 99.99% aluminum has been tried under the current density of 4 mA/mm^2 and the charging time of 40 h using 1N H_2SO_4 solution, and the hydrogen evolution behaviors from both aluminum samples have been investigated by the thermal desorption spectroscopic (TDS) method. The amount of hydrogen evolved from 99.99% aluminum was about three times as large as that from 99.6% aluminum in the 1st-running of TDS on heating up to 630℃ at the rate of 10℃/min. Temperatures of the peaked rate of hydrogen evolution were near at 200℃, 300∿400℃ and 500℃. The evolution rate from 99.99% aluminum at 200℃ was more emphasized by scratching the sample surfaces after the charging. In 99.99% aluminum with as-charged surfaces, a large amount of water molecules, which have been decreased by slightly scratching of sample surfaces, was detected only in the 1st-running of TDS after the charging, in addition to the hydrogen evolution. This suggests that the formation of the hydroxide layer on aluminum surfaces on charging is closely related to introduce the hydrogen into aluminum. | |||||
