摘要：

The effectiveness of Pd-coating on ZrNi against impurity gas exposure was examined. X-ray diffraction profiles revealed that the surfaces of plate and grain samples are readily covered with Pd by electroless plating. Mutual diffusion between the Pd-overlayer and the ZrNi substrate and PdZr formation took place by vacuum hearing above 973 K. Deuterium recovery (DR) in a flowing argon carrier gas containing 5 ppm of impurity gases was examined using packed columns of bare ZrNi and Pd/ZrNi grains. Results indicate that the Pd-coating successfully extends the life time of ZrNi against impurity gases at low temperature below 473 K. Furthermore, no noticeable reduction in DR was found in Pd/ZrNi, whereas bare ZrNi loss its activity at 10 ks at 573 K.
