Interface interaction of tungsten film deposited on glassy carbon under vacuum annealing

Evaluation of diffusion parameters and phase formation between tungsten films and glassy carbon

“…3. This result was a little departure from our earlier finding [23] where the intermixing of W and C atoms appeared to have started at 973 K. This discrepancy can be attributed to the effect of difference in film thickness. The W films used in the present study were thicker than the previous ones, which had a thickness of 62 nm.…”

“…The as-deposited and annealed samples were analysed using the Rutherford backscattering spectrometry (RBS) system with the same analysis parameters given in Ref. [23] and the acquired spectra were simulated using RUMP code. The thickness of W layer deposited, elemental composition as well as information indicative of atomic intermixing across the interface of the diffusion couples were extracted from the RBS-RUMP simulated results.…”

Effects of implantation temperature and annealing on structural evolution and migration of Se into glassy carbon

“…Therefore, the improvement and performance of the materials used to manufacture dry storage devices are vital. Previous studies on the migration behaviour of fission products in glassy carbon have shown that glassy carbon can serve as an alternative material to be considered for the dry cask needed for nuclear waste management [2][3][4][5][6][7][8][9][10][11].…”

Diffusion of strontium implanted in glassy carbon

“…A key property for a nuclear waste storage material is low diffusivity for the radioactive materials. Although there had been a few reports of diffusion of fission product elements in glassy carbon [17][18][19][21][22][23][24][25][26], this is the prime reason for this study, i.e. to determine the diffusivity of the radiological important fission product, strontium, in glassy carbon.…”
