- Titanium Aluminium Nitride (TiAlN) is a thin film coating that was developed from Titanium Nitride.
- TiAlN offers higher temperature resistance than TiN, as well as slightly higher hardness and especially higher hot hardness (i.e. the hardness at high temperatures).
- It is primarily used in high temperature environments above the limits of TiN usage.
- This coating works by forming a thin surface layer of Alumina (Al2O3), or Aluminium Oxide ceramic.
- As the layer wears it continuously reforms.
