Hydrogen absorption and desorption properties of titanium
首发时间:2008-11-18
Abstract:The study on hydrogen absorption and desorption properties of titanium under an initial hydrogen pressure of 0.25 MPa at different temperature was fulfilled, the hydrogen absorption rate constant k value is 7.364×10-3s-1 under an initial hydrogen pressure of 0.25 MPa at 773 K. The depth profile of hydrogen in titanium was performed by secondary ion mass spectroscopy, the relative hydrogen content is invariable between about 700nm and 1250nm in titanium. The X-ray diffraction and scanning electron microscope studies on titanium hydride were performed, the TiH phase was found after hydrogen desorption of titanium at 773 K after heating for 5400 seconds.
