Microstructure, mechanical and electrochemical properties of in situ synthesized TiC reinforced Ti5Si3 nanocomposite coatings on Ti-6Al-4V substrates

- TiC addition improves the mechanical properties of Ti5Si3.based coating.
- Corrosion resistance of TiC-Ti5Si3 coating is comparable to the Ti5Si3 coating.
- Corrosion resistance TiC-Ti5Si3 coating is significantly higher than that of Ti-6Al-4V.
- Calculated donor densities of passive films are similar for TiC-Ti5Si3 and Ti5Si3 coatings.
