中文摘要The micro-crater texture of TiNi alloy was voluminously indented by a mold. Results show that the geometrical parameters of the texture will modify the tribological properties. With increasing of the circumferential pitch and the radial spacing of texture, the friction coefficient and wear rate of TiNi alloy present a decrease at the start, and then an increase after a minimum point. With gradual increasing of the ratio of depth to diameter, the friction coefficient and wear rate of TiNi alloy increase initially and then tend to decrease. When the sliding speed increases, the friction coefficient of TiNi alloy decreases firstly and then increases, following Stribeck curve. With the selected texture parameters such as micro-crater ratio of depth to diameter of 0.06, the radial distance of 1.5 mm, circumferential pitch of 15°, the surface show the best tribological properties of the friction coefficient of 0.098 and wear rate of 0.87× 10-5mm3N·m. It is concluded that the texture with appropriate parameters and shapes can reduce the friction coefficient and wear because of micro-hydrodynamic lubrication and the capture of wear debris from micro-crater texture.
