COURSE DESCRIPTION

Course objectives

After completed course students will have acquired knowledge necessary to prevent corrosion and solve problems caused by corrosion.

Course enrolment requirements and entry competences required for the course

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After completed course students will be able to:
- define and classify corrosion processes
- determine the possible application of certain metallic materials in specific corrosive environments
- implement the necessary corrosion tests
- choose an adequate system of protection against corrosion under specific conditions and assess its durability

Course content broken down in detail by weekly class schedule (syllabus)

1st week: Definition and importance of corrosion. Classification of corrosion processes.
2nd week: Chemical corrosion.
3rd week: Electrochemical corrosion. Passivity.
4th week: The types of electrochemical corrosion of metals. Corrosion rate.
5th week: Corrosion of metallic materials - influence of the media.
6th week: Corrosion under specific conditions: in the atmosphere, water, sea water.
7th week: Corrosion in the soil.
8th week: Corrosion caused by microorganisms.
First test
9th week: Corrosion protection by materials selection and proper designing.
10th week: Materials protection using corrosion inhibitors.
11th week: Electrochemical methods of protection.
12th week: Surface protection. Selection of coatings and paints.
13th week: The importance of inspection and maintenance.
14th week: Corrosion tests.
15th week: Standards.
Second test.
Laboratory exercises: Monitor of atmospheric corrosion. Investigations of metals corrosion rate by polarization methods. Determination of critical pitting temperature of stainless steels. Optical microscopy investigations of corroded metal surfaces. Protection of aluminum and its alloys by anodizing and treatment of the oxide film. Determination of efficiency of organic corrosion inhibitors. Cathodic protection by protector (sacrificial anode)

Format of instruction:

Student responsibilities

Lecture attendance: 80 %. Exercises attendance: 100 %.

Screening student work (name the proportion of ECTS credits for eachactivity so that the total number of ECTS credits is equal to the ECTS value of the course):

Class attendance	1.5	Research	Practical training	1.0
Experimental work	0.0	Report
Essay	0.0	Seminar essay
Tests	2.5	Oral exam
Written exam	0.0	Project

Grading and evaluating student work in class and at the final exam

The entire course can be passed by two partial exams during the semester. Passing threshold is 60%. Each partial exam in assessing participates with 40% and exercises with 20%. On examination shedule students will have oral exam. Scoring: - 60% insufficient, 61 - 69% - sufficient (2), 70 - 79% - good (3), 80-89% very good (4), 90 - 100% - excellent (5).
