KD2380 Corrosion and Surface Protection 7.5 credits

Korrosion och ytskydd

The main objective of the course is to develop fundamental and deep knowledge in the theory for degradation and corrosion of materials in various environments and to present existing protection strategies for prevention of corrosion in different contexts.

The course concerns fundamental theory of the thermodynamics and kinetics of the corrosion process of metals and alloys as well as polymer materials both in atmosphere and water solutions. Focus is put on electrochemical aspects and the influences of the properties of the metals and their oxides on the corrosion behavior, which is exemplified by different corrosion types. Existing corrosion protection strategies, including surface treatments and coatings are described and choice of material is discussed from a corrosion point of view.

In addition to lectures and exercises, the course includes invited lectures from the Swedish industry addressing aspects related to corrosion protection and a group project in which a specific corrosion relevant case is analyzed and discussed both in an oral and a written report.

The main objective of the course is to develop fundamental and deep knowledge in the theory for degradation and corrosion of materials in various environments and to present existing protection strategies for prevention of corrosion in different contexts.

The course concerns fundamental theory of the thermodynamics and kinetics of the corrosion process of metals and alloys as well as polymer materials both in atmosphere and water solutions. Thermodynamics include the consideration and calculation of standard potentials, chemical dissociation constants, Nernst equation, and potential pH diagrams (Pourbaix). Electrochemical reactions governing corrosion of metals and alloys will be addressed both at deaerated, aerated, acidic, and alkaline conditions. Simple calculations and estimations on corrosion rates in solution will be performed based on standard potential tables and Faraday’s law.

The influence of properties of metals and their oxides on the corrosion behavior will be addressed, which is exemplified by different corrosion types. For these corrosion types, the principles (prerequisites, initiation, progress, failure) and ways to avoid that specific corrosion type will be discussed for: atmospheric corrosion, high temperature corrosion, pitting corrosion, crevice corrosion, intergranular corrosion, stress corrosion cracking, erosion corrosion, fretting corrosion, microbiologically influenced corrosion, galvanic corrosion, selective corrosion, and uniform corrosion. It will be analyzed, which corrosion type(s) occur in a specific environment and for a specific engineered material. Materials and environments that will be addressed are the most common engineered metallic materials including carbon and low alloy steels, stainless steels, aluminum (alloys), copper (alloys), titanium (alloys), and nickel (alloys), and environments, including air (indoor and outdoor), surface water, cement and concrete, cooling water, waste water, sea water, and high temperature applications.

The principle, information outcome, and limitations of different corrosion prediction methods will be discussed. Specifically, standard electrode potential tables and Pourbaix diagrams, galvanic series, electrochemical accelerated tests, surface analytical tests, and mass loss and gain measurements, will be compared. Existing corrosion protection strategies, including surface treatments and coatings are described and choices of material are discussed from a corrosion point of view. Specifically, inhibitors, anodic and cathodic protection, and adjustment of environment and material design will be addressed.

Intended learning outcomes *

After completion of the course the student will be able to:

  • Explain and describe different electrochemical/corrosion processes of metals/alloys and degradation of polymeric materials at different conditions, as well as describe different corrosion phenomena, methods for surface treatment and corrosion prevention strategies. 
  • Apply acquired corrosion-relevant theoretical knowledge on practical examples.
  • Develop, put into practice and synthesize knowledge of specific industry- and/or society-relevant corrosion research problems, find underlying reasons for the problems and propose solutions or recommendations for action via targeted written and oral presentations. 

Course Disposition

In addition to lectures and exercises, the course includes industrial lectures related to corrosion protection and a group project in which a specific corrosion relevant case is analyzed and discussed both in an oral and a written report.
