Abstrakt: | The present study examined the corrosion and tribological behavior of novel Ti-5Cu-xNb alloy synthesized via powder metallurgy as a new biomedical material in a simulated bodily fluid (SBF) solution. The electrochemical impedance spectroscopy (EIS) study reveals the formation of two protective layers on the surface of alloys during the test. The alloys spontaneously produce a passivating oxide coating on their surfaces, and the breakdown potential (1.14-1.17 V) and re-passivation current density (2.07-3.04 μAcm -2 ) were observed during the potentiodynamic polarization test. The highest corrosion resistance was observed for the alloy Ti-5Cu-10Nb (i Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.
