Abstract

To explore whether in-situ (TiC + Ti5Si3)/TC4 composites with network structure have simultaneously excellent corrosion and tribocorrosion resistance, the corrosion and tribocorrosion properties of the composites were studied. In-situ TiC and Ti5Si3 particles can effectively enhance the corrosion and tribocorrosion properties of the composites. The composite with 5 vol% Ti3SiC2 exhibits the highest corrosion and tribocorrosion resistance. Grain refinement and the effect of TiC and Ti5Si3 are important factors in enhancing the corrosion and tribocorrosion resistance of the composites.
