OBJECTIVES

 

The course considers the technological requirements that serve the activities of Chemical Engineering, aims to implement knowledge of the materials used for any tough or harsh work environments and then tries to produce the best knowledge of the properties of the materials themselves that technological interventions designed to improve the ability, depending on use. Particular attention is given to the corrosion and protection of materials and radioactive sources.

 

The teaching methodology of the course consists of lectures, tutorials, themes written at the end of the course, to be produced in both of the two most used languages in the technical field (Italian and English).
