Surface Characteristics and Corrosion Behavior Assessment of RF-Sputtered PEKK on Titanium

Abstract

In this study, radiofrequency magnetron sputtering technique (RFMS) was used to coat the titanium with polymer Polyetherketoneketone (PEKK). The corrosion behavior was tested by the electrochemical test in Hank’s solution, the corrosion rate was studied by the polarization test. Furthermore, to investigate the phases of the tested samples XRD technique was performed. The titanium samples coated with polymer were compared to untreated titanium and titanium treated by fiber laser followed by PEKK coated samples.
