Chemical modification of nanocrystalline titanium surface for biological applications
Abstract
Due to unique properties, titanium and titanium alloys are most commonly used metallic biomaterials. Alloing alements in case of long term aplicatons cane lead to metalosis. Because of the significant strengthening, Ti6Al4V alloy can be replaced by pure titanium after grain refinement to the nanometric scale. In this paper, nanocrystalline and microcrystalline titanium Grade 2 was subjected after to two types of chemical modification: soaking in 3 M NaOH for 24 hours at 60°C and annealing at 400°C as well as soaking in a solution of 85% H3PO4 and 30% H2O2 at room temperature. The purpose of modification was to change the topography and the chemical composition of the titanium surface and improve its bioactivity. Titanium surfaces were analyzed using scanning electron microscope (SEM) and TEM before and after modification. The surface chemical composition was examined by Auger electron spectroscopy (AES) using a high resolution electron Auger microprobe Microlab 350 (Thermo Electron).
