不働態--最近20年間の研究動向

摘要

Progress in understanding of passivity and passivity breakdown on iron and iron-base stainless alloys for recent 20 years has been reviewed. Important experimental facts obtained on the structure, composition, and functions of passive films on the alloys were shown and novel mechanisms on the dissolution and passivation of iron was explained. Finally, future subjects that should be done for better understanding of the nature of passive films were proposed.
