Titanium dioxide thin films with nanoporous structures recently gained great interest due to their large surface area and high reactivity properties in their applications. One of the methods used to form titanium dioxide nanostructures is anodizing the surface of titanium and its alloys in F- ion containing electrolytes. Effects of hydrofluoric acid (HF) concentration (0.1 to 0.5 wt.%), anodizing potential (10 to 30 V) and time (30 to 180 minutes) on the titanium dioxide nanotube formation were investigated by anodically oxidizing Ti6Al4V alloy in this study. Scanning electron microscopy (SEM) images were used to detect and monitor the impact of different experimental conditions. In addition, photovoltaic effects from a well-defined cell were used to infer comparative information on the total surface area of nanotubes. The results indicated insignificant effects of HF concentration and anodizing duration on nanotube diameters but direct proportionality to anodizing potential.

Formation of Titanium Dioxide Nanotube Arrays by Anodizing Ti6Al4V Alloy
Karakaya, İshak (The Electrochemical Society, 2014-04-01)
Titanium dioxide thin films of nanoporous structures have gained great interest due to their large surface area and high reactivity properties in their applications. One of the methods used to form titanium dioxide nanostructures is anodizing the surface of titanium in F- ion containing electrolytes.

Effects of tail states on the conduction mechanisms in silicon carbide thin films with high carbon content
SEL, KIVANÇ; AKAOĞLU, BARIŞ; Atilgan, Ismail; Katircioglu, Bayram (Elsevier BV, 2011-03-01)
Hydrogenated amorphous silicon carbide (a-SiCx:H) films of different carbon content (x) were deposited by radio frequency plasma enhanced chemical vapor deposition (PECVD) system. Apart from the X-ray photoelectron spectroscopy (XPS) and UV-Visible transmission analyses, the resistivity measurements between 293 K and 450 K were emphasized to assess the eventual transport mechanisms. The film resistivities are unexpectedly found relatively low, especially for high carbon content. In the frame of exclusive ba...
Use of inorganic natural nanotubes and synthetic carbon nanotubes in poly(lactic acid)
Erpek Yeniova, Canan Esma; Yılmazer, Ülkü; Özkoç, Güralp; Department of Chemical Engineering (2015)
Poly(lactic acid) (PLA) is one of the most important biodegradable aliphatic polyesters, which has attracted great attention in the recent years owing to its excellent material properties. The main objective of this study was to process and characterize Halloysite nanotube (HNT)/PLA nanocomposites. The constituents were observed to be incompatible when processed by classical melt mixing methods, without HNT pre-treatments or addition of plasticizers which act as compatibilizer. In order to achieve the desir...
Effect of CNT impregnation on the mechanical and thermal properties of C/C-SiC composites
Tulbez, Simge; ESEN, ZİYA; Dericioğlu, Arcan Fehmi (2020-06-01)
The present study investigates the effect of additional carbon source, in the form of carbon nanotubes (CNTs), on mechanical and thermal properties of carbon fiber reinforced silicon carbide (C/C-SiC) ceramic matrix composites (CMC) produced by liquid silicon infiltration (LSI) technique. The CNTs used in this study were impregnated into the C/C preforms before the liquid silicon infiltration stage. The results showed that the addition of excess carbon to the C/C preforms in the form of CNTs enhanced Si inf...
Effects of Graphene Transfer and Thermal Annealing on Anticorrosive Properties of Stainless Steel
Oh, Jeong Hyeon; Han, Sangmok; Kim, Tae-Yoon; PARK, JONGEE; Öztürk, Abdullah; Kim, Soo Young (2017-11-01)
Stainless steel (STS) films were annealed in a thermal quartz tube and covered with graphene to improve their anticorrosive properties. Graphene was synthesized via the chemical vapor deposition method and transferred onto the surface of the STS film by the layer-by-layer approach. The structure of the STS film changed from alpha-Fe to gamma-Fe after annealing at 700 C for 1 h, resulting in an increase of 82.72% in the inhibition efficiency. However, one-layer graphene acted as a conductive pathway and ther...
