Course detail

Corrosion and Anticorrosion Protection

FSI-WKOAcad. year: 2011/2012

The subject is focused on material & technology problems of corrosion engineering, with the emphasis put on the systems approach to the methods and tools for anticorrosion protection. The main stress is laid on acquiring basic knowledge necessary for understanding of theoretical fundamentals of corrosion processes, for classification of the corrosiveness of environment and corrosion resistance of structural materials, forms in which corrosion manifests itself, and effects of corrosion processes. This knowledge is a necessary precondition for proposing an optimum anticorrosion protection. In the area of methods and tools forming the system of anticorrosion protection of metals the emphasis is placed on the integration of data on corrosion-favourable materials, possibilities of modifying corrosive environments, and modern protective coatings, including corrosion testing systems.

Learning outcomes of the course unit

The course makes students familiar with the fundaments of metal corrosion, possibilities of anticorrosion protection and with methodology and equipments for corrosion testing. Acquired knowledge can be applied when solving particular problems of corrosion engineering.

Prerequisites

Students are expected to be familiar with the basic types of metal materials, with the relationship between their structure and physicochemical properties, as well as with methods of study of structure and properties of metals. Knowledge of basic chemical reactions is an advantage.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Course-unit credit is conditional on 100% attendance in practicals, working out the reports of practicals according to instructions of the teacher and defending them in a closing interview. Examination: The exam is oral. Student answers 3 questions – 1 theoretical topic on metal corrosion, 1 on methods and means of anticorrosion protection and 1 on corrosion testing. The understanding of a system approach and scope of knowledge of corrosion engineering is emphasized.

Aims

Methods and instruments used for optimal protection of metal products against corrosion. Interpretation of fundaments of corrosion degradation of metals, principles of protective effects of anticorrosion arrangements, basic approaches to corrosion testing in evaluation of corrosion processes, corrosion aggressivity of environments and protective efficiency of anticorrosion systems, creation of database systems and corrosion libraries.

Specification of controlled education, way of implementation and compensation for absences

The attendance at the lectures is optional; with respect to the advanced stage of specialised studies the self-study, professional reports and discussion are preferred. The attendance at the practical training is compulsory and is checked by the teacher. Absence may be in justified cases compensated for by the agreement with the teacher.
