Estudo da corrosão de estrutura metálica em ambiente fabril hostil

Abstract

In the contemporary industrial environment, preserving the structural integrity and efficient maintenance of manufacturing facilities are vital to ensuring safe operation. This study addresses the accelerated deterioration of metal structures in a fertilizer plant, where corrosion, a harmful electrochemical process, is exacerbated in hostile environments. With an initial investigation on an expanded platform plate, the work seeks to understand the types of corrosion, integrating theory and practice through on-site tests. The initial analysis reveals the deposition of elements such as sulfur and phosphorus, originating from the fertilizer selected materials. The objectives include observing and defining the types of corrosion in three chosen materials, SAE 1020 steel, galvanized steel and 304 stainless steel. With the exposure tests of specimens in a manufacturing environment, the predominant types of generalized and alveolar corrosion, with red and white characteristics, were noted. By offering an analysis of the results obtained on site, with a comparison of the efficiency and applicability of the materials, the study contributes to the advancement of scientific technical knowledge in industrial engineering, aiming at the sustainability and efficiency of manufacturing operations.
