In recent years, anodizing equipment has been used for the electrodeposition of magnetic metals or alloys, such as iron, cobalt, nickel, and their alloys, through electrolytic coloring methods. These films exhibit magnetic properties and can be applied in data storage or other magnetic recording technologies. This has found widespread application in the microelectronics industry. The electrodeposition of ultra-hard, self-lubricating electrolytic coloring films has also been developed. Since aluminum itself is soft, anodizing equipment provides a method for surface hardening. The filling of micropores in anodized aluminum with low-shear-stress metals is an effective way to achieve self-lubrication properties, holding significant application value in mechanical engineering.

To utilize solar energy more efficiently, solar-absorbing film materials are required to have high absorption in the solar radiation spectrum and as low an emissivity as possible in the thermal radiation spectrum. For example, nickel electrodeposited into the nanopores of alumina films prepared in phosphoric acid solutions forms functional films with selective solar absorption properties. Reflectivity measurements of the films reveal ideal selective absorption characteristics.

Experimental results indicate that films prepared by electrodeposition methods using metals such as Fe and Ni exhibit significantly higher heat resistance than selective absorption films made from other materials. However, their corrosion resistance is not ideal. Measures such as sealing the pores, applying corrosion-resistant coatings on the film surface, or modifying the surrounding environmental conditions are expected to improve the corrosion resistance of these films.

One primary method involves filling the micropores of porous films with fluorescent substances to prepare photoelectric components. Functional films have been prepared through immersion and heat treatment processes, where the introduction of Tb³⁺ into porous films results in green light emission under an external electric field. The functionalized porous films exhibit high luminescence intensity, suggesting that they could become a new approach for developing optoelectronic devices. Additionally, due to the extremely small pore sizes of the porous films, they hold potential for the development of ultra-fine luminescent devices.

Electrolytic blackening and anodizing can also be used for decorative purposes, such as in optical instruments and camera matte finishing.
