- 摘要:
- 本文分别采用硫酸、草酸以及酒石酸阳极氧化工艺对铝合金支架进行阳极氧化处理,比较了采用不同工艺阳极氧化处理后支架的外观,表征了不同氧化膜的相结构,并测试了不同氧化膜的耐腐蚀性能、硬度和耐磨性能。结果表明,采用不同工艺阳极氧化处理后支架的外观与裸支架基本相同,都具有银白色光泽。不同氧化膜的物相都以Al相为主,还有α-Al2O3相和γ-Al2O3相,且都能提高铝合金基体的耐腐蚀性能、硬度和耐磨性能。与硫酸氧化膜相比,草酸氧化膜和酒石酸氧化膜的性能相对较好,主要归因于草酸和酒石酸对氧化膜的溶解性较弱,制备的氧化膜致密程度较高。酒石酸氧化膜具有良好的致密度,其硬度最高,达到357 HV,耐腐蚀性能和耐磨性能都最好,因此酒石酸阳极氧化工艺更适用于铝合金支架阳极氧化处理,能较大幅度提高铝合金支架的性能。
- Abstract:
- The aluminum alloy support was anodized by sulfuric acid anodizing process, oxalic acid anodizing process and tartaric acid anodizing process respectively. The appearance of support anodized by different process was compared, the phase structure, corrosion resistance, hardness and wear resistance of different oxidation films were tested. The results show that the appearance of the support anodized with different processes are basically the same as that of the bare ones, and they all have silver white luster. Al phase is the main phase in different oxide films, and α-Al2O3 phase and γ-Al2O3 phase are also included in the oxide films, which can improve the corrosion resistance, hardness and wear resistance of aluminum alloy matrix. Compared with sulphuric acid oxidation film, oxalic acid oxidation film and tartaric acid oxidation film have relatively better performance, which is mainly attributed to the weak solubility of oxalic acid and tartaric acid to the film, and thus the prepared oxidation film has high density. Tartaric acid oxidation film has higher density, the highest hardness of 357 HV, the best corrosion resistance and wear resistance, so tartaric acid anodizing process is more suitable for the anodic oxidation treatment of aluminum alloy support, which can greatly improve its performance.
