| Abstract: |
| Cladding was heat treated after electrodeposited chromium-carbon on the surface of zirconium hydride , in order to see mechanics of the hydrogen permeation barrier, zirconium hydride simple was insulated at 7000C for lOh. The constituent of unannealed cladding was analyzed. Surface bonding states of different depths in hydrogen permeation barrier of zirconium hydride were investigated by XPS, and atoms of the barrier were analyzed quantitatively. The results show that carbon and chromium are the main constituents of unannealed cladding. It also show that it exits C, O, Cr, Zr in the barrier. By analyzing the content of the C-H and O-H bonding which are increased after hydrogen permeation experiment ( 7000C thermal retardation) , and the content of the C-H bonding increases more abviously. A conclusion can be draw that Hydrogen is captured by C and O because it can destroy bondings which contain C or O and C is better to the hydrogen permeation barrier than O. |
