Course overview and goals

Long-term reliability of materials in usage environments is one of the most important properties for structural and functional materials. This course provides an overview of environmental degradation of structural and functional materials in various environments based on electrochemistry and surface science. In addition, this course introduces evaluation methods for environmental strength and life time of metallic materials.
This course aims to understand fundamental aspects for corrosion degradation of metallic materials in various environments and to propose appropriate methods of corrosion prevention.
