INDUSTRIAL CHEMISTRY AND TECHNOLOGY
Learning outcomes of the course unit
The course deals with the applications of the fundamentals of Chemistry in the use of engineering materials. It presents a variety of engineering materials, in particular metallic materials, and correlate their chimicophysical nature with their mechanical, thermal and processing properties for explaining their behaviour in service.
General and Inorganic Chemistry, fundamentals of Organic Chemistry
