| Abstract Scope |
Metallic glasses (MGs) have attracted increasing interest in various industries due to their good elastic limit, high strength, and excellent wear and corrosion resistance. For example, Zr-based thin film MGs have been applied in dental implant due to their high strength, exceptional fracture toughness and corrosion resistance. In this work, deposition parameter during magnetron sputtering were tailored to produce Zr-MG coatings with different nanoscale chemistry and microstructure. Corrosion and tribocorrosion tests were performed on all samples in simulated seawater at room temperature. Surface morphology and composition of the samples were characterized using scanning electron microscopy and energy dispersive x-ray spectroscopy prior to and post tribocorrosion testing. Finally, the effects of nanoscale chemistry and microstructure on the corrosion and degradation kinetics of Zr-MG coatings were discussed based on these results. |
