| 中文摘要: |
| 为了提高铝合金硬质阳极氧化膜减摩耐磨性能,在硬质氧化膜的微孔中引入PTFE润滑性粒子,制备了具有自润滑性能的复合膜,并用M-2000型摩擦试验机对其摩擦磨损性能进行了研究。结果表明,制备条件对复合膜的减摩耐磨性能有较大影响。随电流密度的增大,膜的摩擦系数变化不大,耐磨损性能增加;随H2SO4浓度的增加,膜的摩擦系数降低,耐磨损性能降低。此外,复合膜的摩擦系数和耐磨性能随载荷的增加逐渐减小,高速(0.84 m/s)下的摩擦系数比低速(0.42m/s)下的摩擦系数平均高0.17。 |
| 英文摘要: |
| 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). |
