OVERVIEW

The course aims to describe the chemical-physical processes that regulate the interaction of metallic materials with the environment to provide students with the skills for a correct approach to the problem of corrosion. The course will study the theoretical aspects of corrosion phenomena applied to practical cases and will illustrate the main methods of prevention and protection against corrosion.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to provide students with an understanding of the electrochemical fundamentals of corrosion mechanisms. The aim of the course is for participants to acquire knowledge of attack morphologies, the definition of the parameters that contribute to creating critical conditions in the use of metallic materials, and the methods used to control and prevent corrosion. Particular emphasis will be placed on the use of organic coatings as protective agents: 8 hours of class time will be devoted to exercises assessing the operating conditions required for their application and calculating their consumption for the protection of metallic substrates. Six hours of class time will be devoted to a tour of the corrosion and materials protection laboratory: students will have the opportunity to experience many of the experimental measurements described in the lectures.

AIMS AND LEARNING OUTCOMES

Attendance and active participation in the proposed training activities (lectures, laboratory experiences) and individual study will allow the student to:

- understand the fundamentals of corrosion

- Know the techniques of protection, protection and control of corrosive phenomena

-  Evaluate completely the problems of degradation of metallic materials in contact with the external environment.

- Discuss corrosion problems through initial diagnosis assessments and the main causes of phenomena

PREREQUISITES

For a successful learning, basic knowledge of chemistry, mathematics and physics is required, but no formal prerequisites are required.

TEACHING METHODS

The course includes classroom lectures and laboratory experiences designed to promote learning and discussion of specific examples of corrosion applications of metallic materials and related prevention techniques.

46 hours will be dedicated to classroom teaching. Five hours of theory will be developed, as a supplementary course, by corrosion and anti-corrosion specialists from industry.

6 hours of lectures will be dedicated to exercises assessing the operating conditions required for the application of organic coatings and calculation of their consumption for the protection of metallic substrates.

3hours of the course will be dedicated to a visit to the corrosion and materials protection laboratory: students will have the opportunity to experience many of the experimental measurements described in the lectures.

Through the teaching innovation project adopted by the Chemical and Process Engineering Degree Program, innovative tools will be used to encourage active learning. The goal is to enhance student skills through new learning methodologies, from e-learning to teamwork, through experiences that enhance student participation through higher levels of communication and make students more aware and independent.

SYLLABUS/CONTENT

Electrochemical aspects of corrosion

Corrosion forms and morphologies (generalized and localized, pitting corrosion, crevice, mechanochemical corrosion)

Corrosion in industrial environments (petrochemical industry, offshore structures).

Prevention and protection methods (cathodic protection, sacrificial anodes, metallic, inorganic and organic protective coatings)

corrosion monitoring in plants

Analysis of consumption, conditions of application and  degradation of paints considering the different corrosivity classes.

RECOMMENDED READING/BIBLIOGRAPHY

The teaching materials used during the lessons will be available on the course's aulaweb, as will the final exam examples provided in previous years, along with their solutions. The notes taken during the lessons and the materials on the webpage are sufficient for exam preparation.

EXAM DESCRIPTION

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 3 open-ended questions about theory of corrosion, anti-corrosion and electrochemistry, that will be evaluated on the basis of the correctness and completeness of the answer and the correct use of the technical terminology; 1 exercise in calculations on the evaluation of the corrosivity class of an environment, on the definition of an appropriate painting cycle based on the ISO 12944 standard, on the costs for surface preparation and for the application of the chosen coatings, on the environmental conditions suitable for the application and on any checks of the protective cycles following hardening.

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 18/30 and the grade obtained can be only increased at maximun 2/30 more than the written exam evaluation. If the student does not answer to the first question, she/he will not have the possibility to have the second question.

Three exam sessions will be available for the 'winter' session (January, February and during the teaching break provided by the Scuola Politecnica at Easter) and 4 calls for the 'summer' session (June, July, September and during the autumn break provided by the Polytechnic School). No extraordinary exams 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.

Students with a certified learning disability (DSA), a disability, or other special educational needs are invited to contact the instructor at the beginning of the lessons to discuss teaching and examination arrangements that, while respecting the learning objectives of the course, take individual learning needs into account and provide appropriate accommodations.
Please also note that requests for exam accommodations or exemptions must be submitted using the form available at this link 
https://modulionline.unige.it/richiesta-adattamenti#no-back , to the teaching professor, the SCUOLA contact person (federico.scarpa@unige.it), and the relevant office (inclusione.studenti@info.unige.it) at least seven working days before the examination, in accordance with the guidelines available at this link

ASSESSMENT METHODS

Details on how to prepare for the exam and the depth of coverage of each topic will be provided during the lectures. The written exam consists of four questions, including three theoretical questions on general aspects of corrosion, its prevention and protection; attack morphologies and factors influencing material selection and protection methods in service environments; and some general electrochemistry concepts. One exercise on the design of a protective paint system and its associated costs will also be assessed. The oral exam includes two questions on corrosion forms and morphologies and/or corrosion prevention and protection methods. The exam aims to assess the student's ability to apply theoretical foundations to general or specific cases of technological interest and to critically analyze corrosion-related issues. The quality of the presentation, the correct use of technical terminology, and the student's ability to reason critically will also be assessed.
