Abstract To address the coupled failure of oxidation and wear in Ni-based alloys under high-temperature conditions, Ti2SC/TiC multiphase reinforced Ni-based composites were prepared via spark plasma sintering (SPS) by controlling the in-situ reactions of WS2 and Ti3SiC2 precursors. This study focuses on the differential oxidation behavior of the material at 800 °C and its protective mechanism. Microstructural analysis reveals that the Ti-rich reinforcing phases exhibit higher oxidation activity than the matrix, and the volume expansion of their oxide products induces an in-situ oxidative micro-textural reconstruction of the surface. This spontaneous oxide topography not only physically intercepts wear debris but also leverages the ionic potential differences of Ti-oxides to accelerate the oxidative sintering of the debris. The resulting dense glaze layer, driven by oxidation, effectively blocks oxygen inward diffusion and crack initiation. Consequently, the wear rate at 800 °C is reduced by approximately 200 times compared to the matrix, achieving a positive feedback loop where oxidation products significantly enhance high-temperature tribological performance.
