This work includes a theoretical and practical presentation of systems and plants for anodizing of aluminum and aluminum alloys with a presentation of each specific operation. The theoretical part of the work presents the operation of each of the specific process baths of the process of anodizing aluminum and aluminum alloys with the presentation of the preparation or class of cleaning of the items from aluminum and aluminum alloys. The advantages and disadvantages of the process of anodizing aluminum and aluminum alloys are also presented, as well as the chemical substances of some chemical substances used in the process of anodizing aluminum and aluminum alloys. The practical part of the work determines the operating parameters of each process bath, the process of anodizing aluminum and aluminum alloys, and the anodizing plant of the FEAL factory with a technical presentation of the additives used. A sample of anodized aluminum profile marked NP-520 was also used, where the height / thickness of the anode layer is measured with a eddy currents instrument Fischer DUALSCOPE mpor, to determine does the product meets the specified technical characteristics. The last chapter of the work gives a description of some of the alternative technological procedures for obtaining the aluminum oxide layer using technologies such as electrolytic plasma oxidation (PEO) and the theoretical application of various technological approaches using nanotechnology that allow ideal porosity distribution.
