CHEMICAL FOUNDATIONS OF TECHNOLOGIES 1
The course aims to provide the essential physico-chemical basis for the understanding of structure-property correlations in polymeric and metallic materials for their technological applications .
AIMS AND LEARNING OUTCOMES
Attendance and active participation in the proposed training activities (lectures) and individual study will allow the student to:
- Know the polymeric materials and their characteristics
- Completely evaluate problems of degradation of metallic materials in contact with the external environment.
- Estimate the properties of composite materials
- understand the fundamentals of corrosion
- Know the techniques of protection, protection and control of corrosive phenomena
Polymers: Thermoplastic polymeric and thermosetting materials, fibre and elastomers: mechanical and thermal characteristics. Paints and coatings.
Composite materials: physic, chemical and mechanical characteristics of the main compounds, matrix and reinforcements. Manufacturing and ageing (osmosis) technologic aspects.
Metal Materials: structure and microstructure properties, defeats, thermal properties and phase diagrams. Non-ferrous metals and their alloys: light alloy properties and characteristics. Iron and steel metallurgy: thermal treatments and mechanical properties.
Corrosion: Electrochemical basic concepts: galvanic series and marine environment corrosion phenomena. Corrosion prevention and protection techniques.
The teaching material used during the lessons will be available in the classroom of the course, as well as the examples of final tests proposed in previous years with the related solutions. The notes taken during the lessons and the material in the aulaweb are sufficient for the preparation of the exam, but the following book is suggested as supporting and in-depth text.

The exam consists of a written test with optional oral (the student who has passed the written test with a grade greater than or equal to 18/30 can decide whether to take an oral exam on the established days or accept the written test vote).
The writing consists of 4 open-ended questions that will be evaluated on the basis of the correctness and completeness of the answer and the correct use of the technical terminology.
The written test can be repeated, but in this case the vote of the last written delivered is valid.
To access the oral exam students must have passed the written test with a minimum grade of 16/30 and the grade obtained will be the average between written and oral exam.
Three exam sessions will be available for the 'winter' session (January, February and during the teaching break provided by the Scuola Politenica at Easter) and 3 calls for the 'summer' session (June, July, September and during the autumn break provided by the Polytechnic School). No extraordinary appeals will be granted outside the periods indicated by the Polytechnic School, except for students who have not included in the study plan training activities in the current academic year.
It is not allowed to use notes, texts and are not allowed mobile phones. The results of the written test will be published on aulaweb.
Details on how to prepare for the exam and the degree of depth of each topic will be given during the lessons. The written test focuses on 4 theoretical questions on general aspects of corrosion, polymeric materials, composites and metals.
The oral examination includes questions concerning mainly corrosion forms and morphologies and methods of prevention and protection against corrosion in industrial environments, chemical, physical and mechanical characteristics of polymers, composites and metals.
The examination aims to ascertain the ability to apply the theoretical bases to general or specific cases of technological interest and to critically analyze the problems related to corrosion and materials. The quality of the exposure, the correct use of technical terminology and the critical reasoning ability will also be assessed.
