a) A thick steel plate of total area 840 cm2 (bothsides) is exposed to air near the ocean. After 1 year it was foundto have lost 502 g in weight due to corrosion. What is the ratecorrosion, or corrosion penetration rate CPR, for the material inthis environment? Density of steel = 7.9g/cm3 [8 marks]
b) What type of corrosion is this? [2marks]
c) Provide two strategies (there are more than two of course,but just choose two) for dealing with this type of corrosion[2 marks]
d Briefly summarise the pros and cons of each strategy as theymight apply to a children’s playground at a seaside beach front[8 marks].
