- •
The incorporation of Al restrains the decomposition of Ti3SiC2.
- •
The wear rates of TCASc are lower than those of Ti3SiC2 at RT and 200 °C.
- •
Negative wear rate was found for Ti3SiC2 at 800 °C due to tribo-oxidation.
- •
The incorporated phase of AlCu reinforces the bonding of Ti3SiC2 grains.
- •
Abrasive wear and tribo-oxides films lubrication are the main wear mechanisms.
