| Popis: | Porous aluminum anodic oxide films fabricated by anodizing in phosphoric acid electrolyte containing organic acid were investigated. By controlling its microstructure, a macroporous and thick alumina template were obtained. Surface self-lubricating composites were prepared by taking ultra-sonic impregnation in PTFE latex and the relative subsequent heat treatment technology. The studies on the tribological behavior of the surface self-lubricating composite indicated that the tribological properties of aluminum surface can be improved obviously. Compared with the surface coating of hard-anodization, the friction coefficient of self-lubricating composite can be effectively reduced from the 0.575 to 0.166. |
