The research statuses on SABI [rust] chemistry and protective rust layer on weathering steel, compatibility between corrosion resistance improvement and surface hot shortness by Cu in recycling ferrous scrap steels and either side approaches of mechano-chemical and chemo-mechanical reactions in environmental degradation have been reviewed from the viewpoint of looking back over corrosion science and technology in the 20th century. Recent research fruits on the three topics mentioned above are referred to propose future problems.
