Abstract

To improve the high-temperature oxidation resistance of AgCu-based alloy, a three-dimensional TiC nanosheet (3D-TiC_ns) reinforcement was in-situ synthesized in AgCu alloy by melt infiltrating AgCuTi liquid into a graphene sponge. Oxidation kinetics and microstructure evolutions were investigated for the 3D-TiC_ns/AgCu and the AgCu oxidized in air at 500 ℃~600 ℃. The results suggest that the 3D-TiC_ns/AgCu exhibits a superior oxidation resistance at 600 ℃, with the oxidation kinetics transformed from the parabolic law to the cubic law. The 3D-TiC_ns is critical in controlling the internal oxidation, which is inclined to happen in AgCu at 600 ℃. Oxidation resistance enhancing mechanisms are discussed in depth.
