Course detail
Corrosion and Anticorrosion Protection
FSI-WKO Acad. year: 2027/2028 Winter semester
The course focuses on corrosion degradation issues and materials corrosion protection systems. Special emphasis is placed on the mechanism and kinetics of corrosion processes in various environments and applications. Further areas of focus include the classification of environmental corrosivity, corrosion resistance of structural materials, and corrosion testing, as well as environmental treatment options, surface finishing, and surface pretreatment methods for short-term and long-term corrosion protection using metallic, inorganic non-metallic, and organic coatings, along with the application of barrier and inhibition mechanisms, electrochemical protection, and material and design selection.

Entry knowledge
The coursework does not require any extraordinary knowledge or skills. It assumes prior completion of courses in engineering materials and structural design, along with knowledge of basic metallic materials, structural components, and the physicochemical properties of engineering materials, as well as the fundamentals of chemistry, materials physical chemistry, and surface engineering. Additionally, computer literacy (proficiency in Microsoft Word, Excel, and PowerPoint) and a working knowledge of descriptive statistics are expected. Knowledge of polymer chemistry and chemical reactions is an advantage. Familiarity with the subject matter prior to lectures and practical exercises is recommended.
Rules for evaluation and completion of the course
To receive a graded credit, students are required to complete all practical sessions, submit lab reports in either electronic or hard-copy format, and pass a graded colloquium. Evaluation is conducted according to a grading scale from A to E (prepared) and F (unprepared).
Attendance at lectures is recommended; given the advanced stage of study, self-study of mandatory and recommended literature is expected. Attendance at practical sessions is compulsory. For the practical sessions, students must bring writing instruments, a ruler, a calculator, a stopwatch, a device for taking photographic evidence, and any additional equipment specified by the instructor. Any absence from practical sessions must be resolved with the course supervisor.
Aims
The goals of the course are to provide basic professional information in the field Corrosion and anticorrosion protection. It is based on the assumption that knowledge of the mechanism and kinetics of corrosion of different materials are to optimize systems of corrosion protection necessary.
From this perspective, the subject divided in two on consecutive issues (corrosion of materials and anticorrosion protection of materials) in 13 basic topics. Of these, the first eight topics are to introduce the basic principles of materials degradation due to environmental factors. In terms of limited scope is made more detailed description of the corrosion process only for metals, plastics and rubbers. The following five of these topics describes of the basic types of corrosion protection, especially in terms of their purpose, features and applications of the products of different material composition and construction design.
Problem areas are complemented by practical exercises, or by visiting a professional workplace, in order to provide students with a more comprehensive view of reality corrosion and anticorrosion protection in industrial practice.
Learning outcomes form the basis of comprehensive knowledge base and field Corrosion of materials and anticorrosion protection, allowing of the students realizing knowledge in implementing specific projects of corrosion and anticorrosion protection materials of industrial products and consumer goods. In particular, it is the knowledge of the fundamental principles of material degradation due to environmental effects, with an emphasis on various forms of degradation in atmospheric conditions. This allows appropriate selection of construction materials for the anticipated corrosion in chemical environment.
Of the basic types of corrosion protection, especially in terms of their designation, functions and applications of the products of different material composition and structural arrangement are projected output pre-edit process knowledge. Knowledge of protective coatings, based on the description of the basic system produced industrially prepared using paints and paint systems, knowledge making and properties of metallic coatings and coatings of new generation alloy coatings and composites (dispersion) coatings. Another important outcome of the course is the possibility of applying knowledge gained in the field of anticorrosion treatments for transport and storage. This is the first application of preservative oils, protective dispersions, emulsions and impregnating materials, both forms of treatment corrosion systems by destimulation and inhibition.
Presented results of studies in a whole allow listeners used both in research of corrosion, and in design and application of anticorrosion protection in industry with knowledge of the issue.
