Laser surface treatment of Ti-10Mo alloy under Ar and N2 environment for biomedical application
Source abstract
Abstract
This paper evaluated the effects of laser beam irradiation based surface modifications of Ti-10Mo alloy samples under either Ar or N2 environment to the corrosion resistance and cell integration properties. The surface morphology and element distributions of Ti-10Mo samples after laser surface treatments were evaluated using a scanning electron microscope, energy-dispersive x-ray spectroscopy, and x-ray photoelectron spectroscopy. Phase analysis was performed with x-ray diffraction. The electrochemical behavior of the Ti-10Mo samples was evaluated in simulated body fluid maintained at 37 ± 0.5 °C, and a cell-material interaction test was conducted using the MLO-Y4 cells. Laser surface modification in the Ar environment enhanced corrosion behavior, but did not affect the surface roughness, element distribution, or cell behavior, compared to the untreated samples. Processing the Ti-10Mo alloy in N2 formed a much rougher TiN surface that improved both the corrosion resistance and cell-material integration compared with the other two conditions.
