Abstract

Article history: The bioactivity of magnetron sputtered thin film metallic glasses (TFMGs) of Zr Cu Al Ag (at.%) on 48 36 8 8 Received 29 September 2015 titanium substrates was tested for bio implant applications. The structural and elemental compositions Received in revised form 8 January 2016 of TFMGs were analyzed by XRD, XPS and EDAX. X-ray diffraction analysis displayed a broad hump around Accepted 4 February 2016 the incident angle of 30–50 , suggesting that the coatings possess a glassy structure. An in situ crystal Available online 8 February 2016 growth of hydroxyapatite was observed by soaking the sputtered specimen in simulated body fluid (SBF). The nucleation and growth of a calcium phosphate (Ca–P) bone-like hydroxyapatite on Zr Cu Al Ag 48 36 8 8 Keywords: (at.%) TFMG from SBF was investigated by using XRD, AFM and SEM. The presence of calcium and phos- Amorphous materials phorus elements was confirmed by EDAX and XPS. In vitro electrochemical corrosion studies indicated Glass that the Zr-based TFMG coating sustain in the stimulated body-fluid (SBF), exhibiting superior corrosion Surface treatments resistance with a lower corrosion penetration rate and electrochemical stability than the bare crystalline Physical vapour deposition Bioactivity titanium substrate. ©
