Single-Course Danish 5 ECTS

Corrosion and materials under demanding conditions

Overall Course Objectives

To obtain a general knowledge of metal performance and degradation in various environments; atmospheric corrosion, aqueous corrosion, high temperature corrosion, as well as mechanical degradation, including fatigue, wear and creep. It is a course objective to gain knowledge of common corrosion types and to be able to identify the environmental factors for these degradation forms to occur. The course also describes wear mechanisms and anti-wear measures. The student should be able to select the optimal material solution and measures against degradation on the basis of relevant information and requirements for the material (chemical and mechanical influences) as well as from failure analysis. The student should be able to take sustainability and recycling of metals into account when selecting materials for demanding conditions.

Learning Objectives

  • explain the mechanism for degradation caused by corrosion
  • explain typical types of corrosion and their mechanisms
  • compare the corrosion properties of typically used metals and alloys and find such information in material databases
  • describe corrosion protection and select an appropriate corrosion prevention strategy for a given case
  • choose optimal test methods for characterizing corrosion properties as well as being able to calculate corrosion rates
  • demonstrate the main mechanisms for high temperature corrosion as well as the material requirements used for high temperature applications
  • describe the most important wear mechanisms as well as material selection and surface treatments in order to mitigate degradation by wear
  • relate the risk of creep and fatigue failures to specific applications of metals
  • recommend reliable materials under given conditions including recyclability and sustainability aspects andsuggest remedial action based on failure analysis

Course Content

The course introduces basic concepts for degradation of metals caused by corrosion and wear. Topics include: Electrochemistry, corrosion types, corrosion environments, corrosion testing and monitoring, corrosion protection, including cathodic protection, effects of environmental change and use of coatings to prevent degradation. The course also contains a description of high temperature corrosion under various conditions and material use, testing and protection against high temperature corrosion. Wear types and mechanisms as well as description of methods to avoid wear are described. Mechanical degradation mechanisms such as creep and fatigue are described and technological sectors where these degradation mechanisms are addressed.
