Análise de corrosão emum componente aeronáutico ao final de sua vida útil

Abstract

After an accident involving an airplane from Aloha Airlines in 1988, caused by a structural failure of a corroded component, the aviation realized that it was necessary to take preventive actions in the direction of controlling corrosion. Maintenanceand prevention of accidents are closely connected, so studies that aim to show up what the negligence in the maintenance brings are very important. In the present study the cylinder of an airplane engine, what was changed because it had corrosion sign inside it, is the focus of the research. The concepts used in this study are preventivemaintenance, corrosion and engines employed in aviation. The case study seeks, through the realization of tests of corrosion and of revision of the literature, to obtain information that could help to understand the corrosive processes, as well as contributory factors and aggravating circumstances. Finally, the present study try to understand the possible causes that acted on behalf of the corrosiveprocess in the object of study, showing the importance of maintenance in the extension topromote the lifetime of machines and equipment, and promoting the labor safety for the operators.
