A coating system where a more active metal is applied over a less active metal to act as an anode and
protect the underlying metal.
Why is inorganic zinc commonly used as a sacrificial coating over mild steel?
Zinc is more active than steel, so it becomes the anode and protects the steel from corrosion.

To create a physical barrier between the metal surface and the corrosive environment, preventing direct
contact and corrosion.
What is an inhibitive coating?
A coating that releases corrosion inhibitors to slow down or prevent corrosion on the metal surface.
How does a sacrificial coating provide corrosion control?
By using a more active metal as the coating, it sacrificially corrodes instead of the underlying metal,
protecting it from corrosion.
