Synthesis and Optimization of Ti-TiN multilayered protective nanocoatings on Zr-based bulk metallic glass

► Nano-multilayer coatings improve the mechanical properties of bulk metallic glass. ► Decreasing the multilayer's period thickness enhances the tribological properties. ► The nitrogen partial pressure influences the morphological properties of TiN coatings. ► Shear stress depends on type (monolithic or multilayer) and thickness of coatings.
