Nano-architecture Formation on the surface of Ti-based metals by solution chemical processing in room temperature

Abstract

Pure titanium and titanium alloys are used for orthopedic and dental prostheses. Nevertheless, their biocompatibility improvements have still been required. In this study, new preparation technology based on surface modification of titanium-based metals by alkali treatmen has been attempted and reported. After the treatment, surface morphologies were observed by scanning and transmission electron microscopy (SEM, TEM). Chemical composition of the treated surfaces was investigated X-ray fluorescence analysis (XRF). Dissolved elements in the reaction solution were analyzed by inductively coupled plasma (ICP). It was found that the surface morphology consisted from low-dimensional nanostructures was confirmed after the solution chemical treatment.
