What is a Zinc Plating? - Definition from Corrosionpedia

Zinc coatings prevent corrosion of protected metal by forming a physical barrier and acting as a sacial anode - even when this barrier is damaged. Zinc and iron/steel are joined and placed in an electrolyte; a cell is formed, in which the zinc becomes the anode and the steel the cathode. Then, the zinc is saced, and the steel does not rust.

What is a Zinc Plating? - Definition from Corrosionpedia

Zinc plating is also found in the manufacturing of tanks and armored personnel carriers. Zinc should not be used on critical steel parts that can reach temperatures of 500"F or higher, as zinc has the ability to embrittle the steel by diffusing into grain boundaries.

Zinc Plating - The Corrosion-Prevention Workhorse
