A probe has been developed to determine the solubility of hydrogen in metals. The method is based on mass balance and high-pressure hydrogen produced in situ partitioning between a zirconium probe and the metal. As an example, the solubility of hydrogen in copper, S H in Cu , has been determined between 350 and 450 °C: $$ S_{\text{H\,in\,Cu}} = (1000 \pm 200)\exp \left( { - \frac{43000 \pm 1300}{RT}} \right){\text{ [mol H}}_{2} /{\text{m}}^{3} \sqrt {\text{MPa}} ]. $$ S H\,in\,Cu = ( 1000 ± 200 ) exp - 43000 ± 1300 RT [mol H 2 / m 3 MPa ] . This solubility agrees with permeation and diffusivity measurements spanning 10 and 6 orders of magnitude, respectively.

确定氢在金属中溶解度的化学电位探针：以铜为例

已经开发出一种探针来确定氢在金属中的溶解度。该方法基于质量平衡和在锆探针和金属之间原位分配的高压氢气。例如，氢在铜中的溶解度，SH 在 Cu 中的溶解度，已在 350 到 450 °C 之间确定：$$ S_{\text{H\,in\,Cu}} = (1000 \pm 200)\exp \left( { - \frac{43000 \pm 1300}{RT}} \right){\text{ [mol H}}_{2} /{\text{m}}^{3} \sqrt {\text {MPa}}]。$$ SH\,in\,Cu = (1000 ± 200 ) exp - 43000 ± 1300 RT [mol H 2 / m 3 MPa]。这种溶解度与渗透率和扩散率的测量结果一致，分别跨越 10 和 6 个数量级。
