| 摘 要： | By using ion beam sputtering, an 85-A thick nickel layer was deposited on the Zr-A1 alloy (non-evaporablegetter) to improve the characteristic of the hydrogen absorption. The presputtering for 15rain to clean thesurface passivation layer and the vacuum heating treatment of the sample at 750℃ for 1 h for surface alloyingcan improve the ability of the gas absorption. The gas absorption experiments show fast absorption kinetics of thehydrogen pumping and good durability against contaminable gases. The Rutherford-back-scattering spectra andthe secondary ion mass spectroscopy demonstrate the formation of an alloy of Zr, A1, and Ni in the near-surfacearea after the thermal process. The elastic recoil detection analysis indicates that the sample holds the originalhigh capacity of hydrogen.
