Amorphous and dual-phase nanocomposite coatings within Zr‒B‒Cu system
Original language description
The present work aims at the preparation of dual-phase Zr‒B‒Cu coatings composed of a nanocrystalline ZrB2 phase and an amorphous ZrCu phase with metallic glass behavior by non-reactive magnetron co-sputtering and investigation of their structure and properties. The elemental composition was varied so that the stoichiometry of both phases remained the same, but only the volume fraction was changed gradually. We demonstrated that the structure of Zr‒B‒Cu coatings deposited by magnetron sputtering without external heating is amorphous for all compositions. Increasing the substrate temperature promotes the crystallization of the coatings, forming a dual-phase nanocomposite structure based on a nanocrystalline ZrB2 phase and an amorphous ZrCu phase. This effect becomes more pronounced as the volume fraction of the ZrCu phase decreases. Mechanical properties such as hardness and stress are affected by the volume fractions of both phases and exhibit a temperature dependence.
