Abstract:

Corrosion is defined as the deterioration that can occur in metallic components due to electrochemical reactions between the metal itself and the surrounding environment. In the fight against corrosion, basic research can contribute to minimising this type of damage with the aim of delaying its inevitable occurrence. Current lines of research focus on the understanding of corrosion mechanisms and the development of new surface protection systems. At an educational level, in the area of Materials Science, theoretical knowledge on corrosion phenomena has been widely documented over the last few decades. However, are we aware of this problem considering that corrosion causes economic losses estimated at around 3.5% of the world's GDP? In this respect, the implementation of new techniques and methodologies of analysis is essential in university teaching to contribute to the training of students in order to understand how basic research can help us to better understand the mechanisms of corrosion and damage in metals. In this line, a numerical case study is presented, in which the finite element method was successfully used at teaching level, in the Interuniversity Master's Degree in Integrity and Durability of Materials, Components and Structures, in order to facilitate the use of new working tools so that students can more easily understand the importance of knowing the behaviour of certain metal alloys intended to work in aggressive environments. The opinion of the students regarding the numerical-experimental work methodology proposed is also included in this work. In the same way, the impressions of teachers and company personnel related to the area of materials are also collected, with regard to the knowledge of the impact of corrosion on the global economy.
