| 中文摘要: |
| 采用X射线衍射仪、摩擦磨损试验机和扫描电镜等手段，测试分析了固溶态、T6态和ECAP时效态6063铝合金的物相组成、显微组织和摩擦磨损性能。结果表明，固溶态、T6态和ECAP时效态6063铝合金的主要物相都为ɑ-Al相、β-Mg2Si相、β'-Mg1.7Si相和β″-Mg5Si6相，但是ECAP时效态6063铝合金的β相、β'相和β″相的衍射峰更强；相同载荷下，平均摩擦系数和磨损率从大至小的顺序为固溶态>T6态>ECAP时效态，即ECAP时效态6063铝合金具有相对较低的摩擦系数和更好的耐磨性，这主要与ECAP时效处理可以起到细晶强化和弥散强化作用有关。 |

| By means of X-ray diffractometer, friction and wear testing machine and scanning electron microscope,the phase composition, microstructure, and friction and wear properties of 6063 aluminum alloy are tested and analyzed in solution state,T6 state and ECAP aging state. The results show that the main phases of 6063 aluminum alloy in the above three states are all ɑ-Al phase, β-Mg2Si phase,β'-Mg1.7Si phase and β″-Mg5Si6 phase, but the diffraction peaks of β phase, β' phase and β' phase are stronger in ECAP aging state 6063 aluminum alloy;The order of the average friction coefficient and wear rate from large to small under the same load is:solution state>T6 state>ECAP aging state. That is to say, ECAP aging state 6063 aluminum alloy has relatively lower friction coefficient and better wear resistance, which is mainly related with the strengthening effect of ECAP aging treatment on fine grain and dispersion. |
