Estudo de caso a respeito da corrosão encontrada em veículos automotores

Abstract

The corrosion of metals is a natural and universal phenomenon that, throughout history, has posed a significant challenge for the industry, engineering, and materials science. Considering the undesired effects of corrosion in the automotive industry and the importance of understanding it for prevention and control, this study was designed to identify the main causes of this phenomenon in a vehicle dealership and propose corresponding solutions. Using a qualitative methodology, it integrated a case study and bibliographic research to collect data through observations, interviews, and environmental analyses. The study revealed the prevalence of corrosion due to extreme weather conditions, particularly due to proximity to the sea and exposure to winds. Additionally, the presence of rainfall significantly influenced the levels of relative humidity, along with abrupt variations in daytime and nighttime temperatures, which were aggravating factors in the analyzed location. Problems related to the geometry of objects, galvanic pile formation, and the corrosive power of chemical compounds were also observed. Based on these findings, specific mitigating strategies were proposed for each identified situation. It was concluded that, despite the severity of the weather conditions, implementing a set of measures can considerably minimize the effects of corrosion.
