Abstract
This work is based on the lectures which were done three times at the Workshop about Materials for Salt-Making Apparatus, belonging to the Society of Sea Water Science, Japan.
This work is composed of part-1 and part-2. This manuscript is part-1 and intended for the conditions which reaction materials concerned with corrosion phenomena are present at equilibrium. Part-2 is scheduled to be reported in the next issue, and intended for the conditions which participate in corrosion velocity.
Some figures and tables are quoted from well-known corrosion textbooks shown at the end of this manuscript. I wish to express my gratitude to the authors and the publishers.
