| 英文摘要 | Interface stability is one of the key issues determining the service reliability and life of thermoelectric devices. For skutterudite-based thermoelectric devices, the barrier layer is required in order to restrain the inter-diffusion between the hot-side electrode and skutterudite matrix. In this work, Ti88Al12 was selected as the barrier layer. N-type Yb0.3Co4Sb12/Ti88Al12/Yb0.3Co4Sb12 and p-type CeFe3.85Mn0.15Sb12/Ti88Al12/CeFe3.85Mn0.15Sb12 thermoelectric joints were prepared by one-step hot pressing sintering method. The evolution processes of contact resistivity and microstructure were studied through accelerated aging experiments. The results show that the contact resistivity of n-type joints increases slower than that of p-type joints under the same aging condition. Activation energy for n-type and p-type joints is 84.1 kJ/mol and 68.8 kJ/mol, respectively. Growth of the inter-metallic compound layer and cracking at the AlCo/TiCoSb interface result in rapidly increased contact resistivity of n-type joints. For p-type joints, the difference of coefficient of thermal expansion between CeFe3.85Mn0.15Sb12 and Ti88Al12 becomes the main reason for the cracks. |
