| Abstract | Cu–Li–Cu multilayers were deposited on Si substrate by alternately using magnetron sputtering and resistance evaporation. Scanning Electron Microscope (SEM) and Rutherford Backscattering Spectrometry (RBS) were utilized to study the interaction and diffusion between Cu and Li after 8 h heat treatments at 100, 280, and 480 °C. The RBS results reveal that Li can diffuse into Cu when the temperature rises to 480 °C. As a supplementary experiment on Cu corrosion by Li at lower temperature, bulk Li and Cu were annealed at 240, 320 and 400 °C for 8 h separately in a high-temperature furnace after sealing in quartz ampoules. Morphology images show that Li corrodes grain boundaries of Cu preferentially when the temperature is higher than the melting point of Li, and the corrosion rates are 0.7875, 0.925 and 3.3275 mg/h, respectively. The results are helpful for understanding the Cu corrosion and protecting the Cu components in EAST. |
