Multilayer Cr (1−x) Al x N films with a total thickness of 2μm were deposited on high-speed steel by medium frequency magnetron sputtering from Cr and Al–Cr (70 at.% Al) targets. The samples were annealed in air at 400°C, 600°C, 800°C and 1000°C for 1hour. Films were characterized by cross-sectional scanning electron microscopy and X-ray diffraction analysis. The grain size of the...
Reactive radio frequency magnetron sputter-deposited chromium oxide coatings were annealed at different temperatures and times. The influence of annealing temperature on the microstructure, surface morphology and mechanical properties was examined by X-ray diffraction, nanoindentation, pin-on-disc wear and scratch tests, respectively. X-ray results show that the chromium oxide sputtered at room temperature...
