Magnesium corrodes in seawater at a rate of 1.45 gmd. Assuming this to be uniform corrosion, how would you rank the performance of magnesium in seawater. Note that metal is considered resistant, satisfactory and not satisfactory when the corrosion rate is less than 0.15 mm/y, between 0.15 and 1.5 mm/y, and more than 1.5 mm/y, respectively. The density of magnesium is 1.738 g/cm3.

Magnesium corrodes in seawater at a rate of
1.45 gmd. Assuming this to be uniform
corrosion, how would you rank the performance
of magnesium in seawater. Note that metal
is considered resistant, satisfactory and not
satisfactory when the corrosion rate is less than
0.15 mm/y, between 0.15 and 1.5 mm/y, and
more than 1.5 mm/y, respectively. The density
of magnesium is 1.738 g/cm3.
