Web17 sep. 2024 · The rapid surface diffusion has enabled low-temperature direct bonding in the range of 150 to 200 °C under an ordinary vacuum of 10 −4 to 10 −3 torr. WebWith low joining temperature and low Ti content, a ductile banded Cu/TiCu 4 layer forms between graphite and Nb by peritectic reaction. The dissolution‐precipitation of Nb in TiC particles can help to reduce the brittleness on graphite interface. The TLP bonding between Nb and copper results in a narrow diffusion layer in copper substrate.
