Worked Solution & Example Answer:(c) Identify any three barrier materials that may be applied to mild steel to protect against corrosion. - Leaving Cert Engineering - Question c - 2011
Step 1
Identify three barrier materials
Answer
-
Galvanising: This involves coating steel with a layer of zinc to provide a protective barrier against corrosion. The zinc serves to sacrifice itself, preventing rust formation on the underlying steel.
-
Spray Painting: Applying a protective layer of paint helps isolate the steel from atmospheric moisture and other corrosive elements. The paint acts as a barrier, shielding the metal from exposure to atmospheric conditions.
-
Plastic Coating: Covering mild steel with a layer of plastic provides a robust protective barrier against moisture and corrosive agents, effectively reducing the risk of corrosion.
