Anodized Tantalum Surfaces for Orthopedic Applications Uslu, Ece; Ercan, Batur (null; 2018-04-30) Currently used implant materials do not suffice the needs of patients mainly due to their poor osseointegration with the juxtaposed bone tissue, which ultimately leads to failure of the implant. To overcome this issue, better orthopedic implants exhibiting bioactive characteristics are required. Tantalum is a good candidate as a new generation orthopedic implant materials due to its superior mechanical and chemical properties compared to the currently-used metallic implant materials. However, its bioinert n...
Anodization of 316L stainless steel for implant applications Erdoğan, Yaşar Kemal; Ercan, Batur (2021-06-10) 316L stainless steel (SS) surfaces were modified via anodization to form nanopit structures with aim of improving its corrosion resistance, bone cell adhesion, proliferation and enhance its bioactivity. Surface characterization studies revealed that nanopit structures were composed of Fe2O3 and Cr2O3. The in vitro results showed that nanopit surfaces enhanced bone cell proliferation. Thus, we concluded that fabrication of nanostructures on 316L SS surfaces is a promising way to enhance bone cell functions f...
Anodization of titanium alloys for orthopedic applications Izmir, Merve; Ercan, Batur (Springer Science and Business Media LLC, 2019-03-01) In recent years, nanostructured oxide films on titanium alloy surfaces have gained significant interest due to their electrical, catalytic and biological properties. In literature, there is variety of different approaches to fabricate nanostructured oxide films. Among these methods, anodization technique, which allows fine-tuning of oxide film thickness, feature size, topography and chemistry, is one of the most popular approaches to fabricate nanostructured oxide films on titanium alloys, and it has been w...
Anodization of titanium alloys for orthopedic applications İzmir, Merve; Ercan, Batur; Department of Metallurgical and Materials Engineering (2018) In recent years, nanostructured oxide films on titanium alloy surfaces have gained significant interest due to their electrical, catalytic and biological properties, leading to an extensive effort to engineer nanostructured oxide films on titanium and titanium alloy surfaces. In literature, there is a variety of different approaches to fabricate nanostructured oxide films, including hydrothermal treatment, sol-gel synthesis, physical vapor deposition, electrodeposition, and etc. Among these methods, electro...
Anodized Nanostructured 316L Stainless Steel Enhances Osteoblast Functions and Exhibits Anti-Fouling Properties Erdoğan, Yaşar Kemal; Ercan, Batur (2023-01-01) Poor osseointegration and infection are among the major challenges of 316L stainless steel (SS) implants in orthopedic applications. Surface modifications to obtain a nanostructured topography seem to be a promising method to enhance cellular interactions of 316L SS implants. In this study, arrays of nanodimples (NDs) having controlled feature sizes between 25 and 250 nm were obtained on 316L SS surfaces by anodic oxidation (anodization). Results demonstrated that the fabrication of NDs increased the surfac...
