Electrochemical and Mechanical Properties of Cast Ti-V Alloys for Dental Applications

摘要

A series of Ti-xV alloys with a vanadium (V) content ranging from 5 to 20 wt% were fabricated toinvestigate phase/microstructure, various mechanical, and electrochemical properties. Themicrostructural samples were characterized using X-ray diffractometry (XRD), scanning electronmicroscopy (SEM) and transmission electron microscopy (TEM). All the Ti-xV alloys showedcolonies of hexagonal close packed (hcp) -phase lamellae within large body centered cubic (bcc) - phase grains of several lath boundaries. As a result of solid-solution strengthening of -Ti and -Tiphase matrix, the Ti-xV showed better mechanical properties than the commercially pure titanium (cp- Ti). Based on the electrochemical results, the Ti-5V alloy exhibited improved corrosion resistance ascompared with cp-Ti.
