Benefits of technology

The patent describes a method to strengthen and improve the surface and mechanical properties of aluminum plates by anodizing them. The technical effect is that anodized aluminum plates have better strength and surface quality.

Problems solved by technology

However, ceramics are poor in moldability, workability, and rigidity as an exterior material when compared with aluminum alloys.
Anodized aluminum alloys implement a metallic texture, but cannot provide a soft-looking appearance that is provided by a ceramic surface.
In addition, conventional anodized aluminum alloys cannot implement a white color preferred by many consumers, and since the metal texture is not uniformly exhibited, it is difficult to apply the aluminum alloys as an exterior material for electronic devices.

embodiment 1

[0058]In Embodiment 1, GU values are measured after physical polishing is performed on the surfaces of the provided aluminum alloy materials 110 and 120.

[0059]As a result of performing the above physical polishing process, the maximum GU value is measured as 748.9, and the minimum GU value is measured as 717.7. The average GU value is 732.6.

embodiment 2

[0060]In Embodiment 2, GU values are measured after blasting is performed on the surfaces of provided aluminum alloy materials 110 and 120.

[0061]As a result of performing the blasting process, the maximum GU value is measured as 16.0 and the minimum GU value is measured as 15.5. The average GU value is 15.9.

[0062]From the analysis values by a surface glossmeter for the aluminum plate 130 formed after different surface processes were performed on the aluminum 6xxx series alloys of Embodiments 1 and 2, the aluminum plate 130, which was subjected to the physical polishing process, can obtain a relatively high gloss compared with the material, which was subjected to the blasting process.

[0063]An electrolytic polishing process may make the surface of the aluminum alloy material 110 smooth and / or glossy using an anodic dissolution phenomenon. For example, the electrolytic polishing process may be performed in such a manner that the aluminum alloy material 110 is accommodated in the electr...

embodiment 3

[0083]In Embodiment 3, the provided aluminum alloy materials 110 and 120 are anodized at a temperature ranging from 5 to 30° C. and at a voltage in the range of about 12V for 5 to 180 minutes. As a result of performing the anodizing treatment, the maximum GU value is measured as 175.2, and the minimum GU value is measured as 167.0. The average GU value is 171.7.
