In order to improve the hydrogen kinetics Pd-coating were carried out on each side of the amorphous ribbon. Pd prevents oxidation of Zr and catalyses the dissociation of molecular hydrogen to atomic hydrogen. In this work, the hydrogen embrittlement and surface properties on Zr-based amorphous alloys were investigated. The Zr-based amorphous alloys were characterized by X-ray diffractometry(XRD) and differential scanning calorimetry(DSC). The morphology of surface and roughness was observed by using scanning electron microscopy(SEM) and atomic force microscopy (AFM). A lattice parameter of both Pd and Zr-based amorphous alloy was increased after hydrogen permeation at 473 K. After hydrogen permeation at 473 K, some cracks were observed on the surface of Pd, which was the cause for the hydrogen embrittlement. The crystallization temperature of Zr-based amorphous alloy was decreased due to the permeated hydrogen. 한국수소및신에너지학회 Pd 코팅된 Zr기 비정질 합금의 수소취성 및 표면특성 Hydrogen Embrittlement and Surface Properties ofPd-coated Zr-based Amorphous Alloys Article 2 한국수소및신에너지학회논문집, v.18, no.2, pp.182 - 188 한국수소및신에너지학회논문집 18 2 182 188 kci ART001061914 amorphous alloys melt-spining metal membrane hydrogen embrittlement 비정질재료 멜트스피닝 금속분리막 수소취성
