Abstract
Based on the microporous structure lubrication method, Ti6Al4V(TC4)-based self-lubricating composites (TC4-SAC) with microporous channels filled by lubricant Sn-Ag-Cu are prepared. The effects of microporous channel parameters on stress and deformation of TC4-SAC are analyzed by finite element method. In addition, the friction and wear behaviors of TC4-SAC with different microporous channel parameters are compared, and the self-lubricating mechanisms of TC4-SAC are also analyzed. The results show that microporous channel parameters have a significant influence on the mechanical and tribological performance of TC4-SAC. Moreover, when the vertical depth of microporous channel = 3.5 mm, the micropore pitch = 3 mm, and the micropore diameter = 0.8 mm, TC4-SAC can obtain the best mechanical property and self-lubricating characteristic.
