Obiettivi dell'insegnamento

The course aims at describing the main corrosion phenomena on metals in contact with natural (soil, atmosphere, water) and industrial environments. The students will be able to make a corrosion assessment, evaluating the maximum expected corrosion rate and making a proper material selection for a specific application as a function the environmental aggressiveness and operation condition. Among the several available protection techniques, cathodic protection will be described in details.

During the lesson, a real case will be presented. Students, divided in groups of maximum five, will be asked to make a corrosion assessment, defining the cause of corrosion and indicating a proper protection system to assure a safe use in operating condition. At the end of the course, any group has to write a technical report on the proposed subject.


Risultati di apprendimento attesi

Lectures, numerical exercises and practical examples will allow the student to:

- define, for each environment, the parameters necessary to evaluate the corrosion rate

- know the possible forms of corrosion of a metal in contact with a specific environment 

- make a corrosion assessment, discussing on the possible cause of corrosion, estimating the corrosion rate

- discuss and select a proper metal or a proper protection technique for a specific application

- know the cathodic protection systems and select a proper plant for a real structure

The project laboratory will allow students to:

- discuss in a team on a real corrosion problem

- find a suitable remedy to the damage, using applicable technical standards

- write a technical report in which both the cause of corrosion and the application of a protection system are described


Argomenti trattati

The course is taught in the first emi-semester and it deals with the following topics.

Basic principles of corrosion (outline). Electrochemical mechanism. Thermodynamic and kinetic aspects.

Corrosion and protection of metals in natural environments (related issues: main forms of corrosion, causes of corrosion, evaluation of corrosion rate, use of corrosion prevention systems, metals most used and specific corrosion issues). Atmosphere: effect of pollutant, RH, temperature. Soil: soil composition, stray current, differential aeration, SRB. Fresh water and seawater: indexes, scaling power, hardness, conductivity. 

Corrosion and protection of metal in Oil & Gas industry. Off-shore and on-shore, oil production and transportations, CO2 corrosion, H2S corrosion, erosion-corrosion. Corrosion in industrial boiler.

Cathodic protection. Galvanic and impressed current system, anodic materials, feeding system, design and monitoring.

A project laboratory is integral part of the course. The objective of projects is to help students in applying the approaches and principles tough during the class. Projects will be assigned through the semester. The final report is expected to be released at a fixed deadline, which will be defined by the time the project will be assigned. The evaluation of the projects will be based on the produced report.


Prerequisiti

Basic knowledge of principles of corrosion, metallurgy and electrotechnics.


Modalità di valutazione

The evaluation will be carried out by a written exam.

An intermediate written exam will be scheduled at the end of the emi-semester of lessons, during the week of lesson suspension according to the official academic calendar.

The written exam consists of two open questions and two numerical exercises. Aim of the written exam is to verify the student ability to know the corrosion issues of metals in real working conditions and to verify if the student is able to make a proper corrosion assessment, estimating the corrosion rate, evaluating the residual service life or applying cathodic protection as main preventative or protection methods. Exam during the official dates are organized in the same way.

The maximum score for the written exam is 30/30. The written exam is passed even if the grade obtained is 15/30.

The project laboratory report will be evaluated based on the proper corrosion assessment, the definition of the cause of corrosion and the proposal of a correct remedy. Structure of the report and clarity of exposition will be considered, too. The maximum score of the project laboratory report is 3/30. This score is sum up to the written exam score.

The oral exam is optional and can be sustained only after a successful written exam. With the oral, a maximum increase of 3 points can be obtained. If the oral is not satisfactory the score can be reduced.
