The investigated microstructure and mechanical properties of Al 2O3/20wt% TiO2 nanocomposite coating

The investigated microstructure and mechanical properties of Al 2O3/20wt% TiO2 nanocomposite coating

The incorporation of nano-size TiO2 particles can significantly enhance the microstructure and mechanic properties of Al2O 3 coating. Phase transformation from mainly stable α-Al 2O3 and anatase-TiO2 in the powders to predominant metastable γ-Al2O3 and rutile-TiO 2 in the coatings was observed. Reac...
