| Abstract: |
| In order to improve the properties of friction reducing and wear resisting of aluminum alloy hard anodic oxidation film, the self-lubricating oxidation film was prepared by importing PTFE particles into the pores of hard anodizing film. The tribological properties were tested by M-2000. The results illustrate that the preparation conditions have an obvious effect on the tribological properties of the film. The wear resisting increases and friction coefficient almost unchange as the current density increasing, while the friction coefficient and the wear resisting of the sample reduces with increasing of the sulfuric acid content. Furthermore, the friction coefficient and wear resisting of film decrease with the increasing of load, and the friction coefficient of the film in high sliding rate(ie. 0.84 ms- 1)almost increased 0.17 than it in the low one(ie. 0.42 ms- 1). |
