Özet

The goal of this study is to fabricate a biomaterial implant composed of Titanium alloy TiAl6V4 coated with poly (εcaprolactone) (PCL) using electrospinning mechanism. Moreover, the effect of surface-treatment for the titanium alloy on the coating is also studied, whereas coating thickness is determined using a micrometer. Characterization of specimens’ morphology is executed using Scanning Electron Microscopy (SEM). The wettability of the surface is performed using the contact angle (CA) and the optical micrographs of the Titanium alloy microstructure are carried out using optical microscopy. The detection of composition and elements in the substrates Energy dispersive spectroscopy (EDS) is also performed. For more quantitative analysis of surface morphology and to evaluate the roughness at the surface of implants, AFM and roughness measurements are used. To determine the adhesion of the PCL to the TiAl6V4 , adhesion test is conducted. EDS shows that the obtained specimens are free from any other elements after being treated. The optical microscopy is used to observe the changes in the microstructure through optical micrographs, after pre-treating the alloys. Through SEM, the change in the surface morphology after grinding, polishing, and etching is also recorded. The roughness measurements indicate the mean values of roughness quantitatively, which are gradients from 0.005 micron in 3 micron polishing TiAl6V4 sample to 0.56 micron in the 120 grinding TiAl6V4 sample. After measurement, the thickness of the coating is determined as 0.01 mm. The contact angle measurement shows that the best sample in hydrophilicity is the etched alloy after coating it with PCL, which is 58.63 °. The adhesion test also proves that the best two samples for coating adhesion are the etched and 1200 grinding: more than 99% of the coating do not stick out of the coating after the removal of the tape.
