AB  - Machining technology is a widely used chip technology designed for the production of segmented parts. It is widely used in almost all branches of industry, including the automotive industry. Here, the investigated alloy 2024 is widely used. A critical factor in the current design of many of these advanced systems is accurate knowledge of degradation behavior in the work environment in the context of surface condition after surface machining. If this environment causes surface discontinuities, they will significantly affect the life of the part. Corrosion behavior is considered to be an extremely critical factor due to its effect on the service life of the structure. Due to the many complexities that have developed in relation to surface condition and corrosion, little useful technical information is available. The aim of the article was to determine the effect of the surface condition on the corrosion behavior of alloy 2024. The chemical composition of the alloy was evaluated by spectral analysis. Furthermore, the samples were evaluated by confocal microscopy and the elemental distribution in the microstructure of the 2024 alloy was analyzed with emphasis on the Al2Cu phase distribution. The individual structural phases were performed using a scanning electron microscope with an EDS analyzer. This article is part of a larger experiment that will focus on the subsequent modification of this alloy, in order to change the microstructure and skin resistance of castings.
