structure (α phase) appears to be the only thermodynamically stable phase with excellent hardness at high temperatures. Although α-Al2O3 is widely used for hard-coating material [ the deposition temperature of α-Al2O3 coating by conventional thermal chemical vapor deposition (CVD) is about .

2017年9月25日 · θ-Al 2 O 3 ultrafine powder has been synthesized using co-precipitation technique. The stable phase behavior in the range 900–1200 °C was obtained. Hexagonal agglomeration shape is formed at the low annealing temperature. The measured optical band gap of θ-Al 2 O 3 by UV–Vis. was found about 5.8 eV.

2019年2月15日 · When an (hkl) texture designation is used in this study, it is implied that i = −(h + k). The (hkl) designation also implies that the crystal plane is aligned parallel to the sample surface [ 3 ]. The advantage of introducing texture into the α-Al 2 O 3 coating layers grown onto cutting tools relies on the anisotropy in bond strength, and ...
