Abstract

The structural and electrochemical properties of a selective laser sintered porous Ti-10Mo alloy were investigated. As the sintering temperature increases from 1100 to 1400. °C, the porosity and pore size decrease from 63% to 28% and from 178 to 56. μm, respectively. The alloy comprises major α and minor β phases at room temperature. With the decrease of porosity, the corrosion potential shifts towards positive direction and corrosion current density reduces, while the passive current density decreases and passivation range widens. The lower porosity, smaller pore size and slightly increased β phase fraction cause a superior corrosion resistance.
