Desenvolvimento de camadas nanoestruturadas inteligentes para a deteção de corrosão em estruturas aquáticas (SMARTAQUA)
ParticipanteFundação para a Ciência e a Tecnologia
Corrosion is a result of thermodynamically-driven processed which occur due to the interaction of active metal alloys with the surrounding environment, leading to the degradation of metallic structures. The problem is particularly relevant in maritime offshore structures due to aggressive conditions such as high salinity and humidity.
