The invention relates to preparation of ternary biocompatible thin films metallic glasses based on ZrCu-X, where C can be one of the elements Ca, Mg, Mo, Si, Sr, by cathodic arc evaporation method used for coating of orthopaedic implants. Thin films are amorphous with 2 µm thickness, adherent to substrates and hard (10 -20GPa), with contact angle ranged from 115º to 134º. Thin films are resistant to corrosion in SBF at 37 °C, with a high protection efficiency (>58%) and good biomineralization abilities in SBF and DMEM solutions, having the adsorption of bovine serum albumin (BSA) higher than the uncoated surfaces.
