The Zr-Co alloy is a promising tritium (T)-storage material and has been extensively studied. The helium decayed by T will gather to form bubbles, which are very harmful to the material. The temperature and helium content strongly affect the behavior of helium in the material. In this study, 4He was absorbed in Zr-Co films by magnetron sputtering deposition to simulate the behavior of the 3He decayed by T in T-storage materials. Different He ratio samples were fabricated by radio frequency (RF) magnetron sputtering deposition. The film composition and He ratio in Zr-Co were determined by Rutherford back scattering (RBS) and elastic recoil detection (ERD), respectively. Thermal desorption spectroscopy experiments and X-ray diffraction (XRD) analysis were used to investigate the states of the He in the samples and the microstructure of the samples, respectively.

Key words: Zr-Co, He behavior, Tritium-storage material
