- 摘要:
- 选用 2099 铝锂合金作为基体进行硬质阳极氧化,并研究电压对硬质阳极氧化膜形貌特征、成分、厚度、硬度、耐磨和耐腐蚀性能的影响。结果表明:随着电压从 50 V 提高到 90 V ,硬质阳极氧化膜的结构趋于致密,然后变得疏松,表面粗糙度先降低后增加,厚度先增加后降低,导致硬度、耐磨与耐腐蚀性能表现出明显的差异,但硬质阳极氧化膜的元素组成未变。电压为 70 V 制备的硬质阳极氧化膜表面结构致密,厚度达到 27.3 μ m ,具有高硬度( 457.4 HV )、良好的耐磨和耐腐蚀性能,平均摩擦系数和腐蚀电流密度仅为 0.49 和 2.02×10 -6 A/cm 2 ,对铝锂合金的防护效率达到 95.1% 。由于电压提高逐步形成较致密的硬质阳极氧化膜并促使膜层增厚,承载能力、抵抗局部塑性变形能力、阻碍腐蚀介质渗透和抵抗腐蚀能力增强,因此硬质阳极氧化膜的性能明显提高。
- Abstract:
- : 2099 aluminum-lithium alloy was treated by hard anodizing process , and the effect of voltage on the morphology , composition , thickness , hardness , wear resistance as well as the corrosion resistance of hard anodized film was studied. The results show that with the increase of voltage from 50 V to 90 V , the structure of hard anodized film tends to be dense and then becomes loose , the surface roughness first decreases and then increases , the thickness first increases and then decreases , resulting in obvious differences in the hardness , wear resistance and corrosion resistance , but the element composition of hard anodized film does not change. The hard anodized film prepared at 70 V has dense structure with a thickness of 27.3 μ m , possessing high hardness ( 457.4 HV ), excellent wear resistance and corrosion resistance. The average friction coefficient and corrosion current density are only 0.49 and 2.02×10 -6 A/cm 2 , and the protection efficiency on Al-Li alloy reaches 95.1%. A hard anodized film with compact structure is gradually formed and the thickness is increased due to the increase of voltage , and the bearing capacity , resistance to local plastic deformation and resistance to corrosive media penetration are enhanced , so the properties of hard anodized film is significantly improved.
