Abstract:
Several problems present in our daily lives are directly related to the degradative effects of corrosion, due to the extensive use of metallic parts, structures, and equipment in various fields. The impacts caused by corrosion affect both physical and economic aspects, resulting in significant losses and endangering both the environment and the people involved. Metallic coatings offer improvements in the mechanical properties of metals, increasing resistance to corrosion. This study aims to analyze the corrosion process of ASTM A36 and SAE 1010 steels coated with Zinc-Aluminum-Magnesium alloy in a saline mist environment, in order to assess the efficiency of the alloy in atmospheres with aggressive microclimates. Metallic coatings, such as Zn-Al-Mg alloy, prove to be promising in protecting against corrosion in demanding environments, contributing to the extension of the lifespan of metallic materials. Through a superficial visual analysis, it is possible to observe that the Zn-Al-Mg alloy coating exhibits significant corrosion resistance compared to uncoated steels. However, in addition to the experiments conducted in the Salt Spray chamber, for a detailed analysis of the coating and its limits, investment in chemical and structural analysis will be necessary.
