Teaching Method

Outline:

Based on the Environmental Intensity I course, we take examples of atmospheric corrosion, stress corrosion cracking, high temperature oxidation, etc. that can occur when actually using materials, understand the mechanisms by which materials corrode, and take measures against corrosion protection measures. The purpose of this class is to be able to master basic knowledge.

Style:

lecture

Notice:

·It is desirable that you take Environmental Strength I.
·Reports, etc. are required to be submitted for all subjects. Except in the case of unavoidable circumstances, we do not approve the unit if the deadlines are not met.
·We may change the lesson plan according to the student’s degree of understanding.
