PDF-1 [SCC/BM] BASICS OF CORROSION

1 SCCBM Aluminium alloys Magnesium How can bimetallic corrosion be prevented By isolating the metals electrically using insulators By isolating the metals from the environment using a coating By. The most common example of corrosion is the formation of rust on steel Most corrosion phenomena are of electrochemical nature and consist of at least two reactions on the surface of the corroding metal One of the reactions is the oxidation eg dissol Dr. Zamanzadeh (Zee).

Question: You discover that one of your deceased relatives earned medals during both the Second World War and the Korean War and you are very proud of your relative’s contribution to his country. They have been given to you by inheritance. They are in perfect condition. How would you be able to display them while not damaging them to the elements (to the environment)? .
