Modification Of Titanium

Titanium is well known as an implant material having excellent biocompatibility and mechanical properties for use in bone substitute. In the present study, to enhance the biocompatibility of titanium, its surface was modified by hydrothermal treatment using dilute alkaline solution. After hydrothermal treatment, anatase predominantly formed on a titanium surface. The anatase phase showed high crystallinity and c-axis orientation. The anatase layers with leaf-like and pyramid-like forms were observed on titanium autoclaved at 120 °C and 240 °C, respectively. The anatase formation and its morphology were significantly related to the autoclaving temperature. To estimate the cellular compatibility of the autoclaved titanium, mouse osteoblast-like cells (MC3T3-E1 cells) were cultured on the autoclaved titanium surface. After 7- days culturing, the number of the cells harvested from the autoclaved titanium was higher than that from untreated titanium. The surface modification of titanium by hydrothermal treatment involved the proliferation of the cells on its surface.

Modification Of Titanium

Hydrothermal treatment was performed on a titanium plate for its surface modification to enhance its bioactivity. The titanium plate was autoclaved in deionized water (DW) or 0.05 mol/l NaOH solution at 120, 200 and 240 °C for 24 hr. The titanium surfaces autoclaved in DW were homogeneously coated with nano-sized particles and polygonal deposits with the sizes of several hundreds nanometers. The deposits were regarded as anatase according to the results of laser Raman spectroscopy (LRS). In the case of autoclaving in 0.05 mol/l NaOH solution, leaf-like, needle-like and pyramid deposits were observed on titanium surfaces and regarded to consist of anatase or brookite by LRS analysis. The formation of the deposits significantly depended on the autoclaving temperature. The deposits adhered on the titanium surface though a tape-test; the adhesion of the particle was found to be excellent.
