Abstract
The dense columnar structure of the intermetallic coatings (hardness values between 2.5 and 10.2â¯GPa) turns into a nano-composite-like morphology for depositions with 50 and 100â¯sccm O2 p.a.s., which in turn leads to a significant hardness increase up to ~24â¯GPa. Among all coatings investigated, the Cr-rich compositions have higher hardness and denser morphology than the Al-rich layers.
