由于0.01mm的未涂覆Al2O3的区域间隙与FeCrAl直接接触,间隙的氚浓度被FeCrAl内表面吸附过程由Sievert' law方程控制。Al2O3中的氚浓度也低于FeCrAl中的氚浓度,氚在未涂覆Al2O3的区域对应的FeCrAl浓度最大,从这一处向周围的FeCrAl氚浓度梯度逐渐递减。
Since the 0.01 mm uncoated Al2O3 region gap is in direct contact with FeCrAl, the tritium concentration of the gap is adsorbed by the inner surface of FeCrAl The process is controlled by Sievert' law equation. The concentration of tritium in Al2O3 is also lower than that in FeCrAl, which corresponds to the largest concentration of FeCrAl in the region without coating Al2O3, and the gradient of FeCrAl tritium concentration gradually decreases from this point to the surrounding FeCrAl.
