In this project, novel ZrCu-based ternary to quinternary Thin Film Metallic Glasse (TFMGs), comprising 3 to 5 constituents, are proposed to be prepared as protective coatings for dental/orthopaedic implants or for their metallic components which are in direct contact with bone. A novel TFMG type consisting of Zr-Cu-X where X will be Si, Mg, Ca, Sr, Mo in various combinations will be produced. It is expected that such structures will possess high hardness, good adhesion to metallic substrate, elastic modulus close to those of bone, low internal stress, resistance against wear and corrosion, low friction and wear rate, good bioactive, osseoconductive and antibacterial properties, leading to an increased service life of the implants.
