The as-deposited film was found to be fully amorphous with high glass transition and crystallization temperatures of 466¢XC and 502¢XC, respectively. Its hardness progressively increased from 6.2GPa to as high as 11.1GPa when subjected to annealing near the glass-transition temperature at 450¢XC. It was also of good adhesive strength and scratch resistance after the annealing treatment at 400¢XC. Transmission electron microscopy results revealed annealing-induced nanocrystals that accounted for such superior mechanical properties. With the above unique properties, Zr-Ti-Ni thin film metallic glass has the potential for the fabrication of high strength micro parts and protective coating. ? 2014 Elsevier B.V. |
