The galvanized layer on iron wire coated with zinc has multiple key functions:
The primary function is to prevent corrosion, the galvanized layer for the wire with a solid protective coat, effectively isolate the air from oxygen, moisture and other corrosive elements, greatly delaying the corrosion process of the wire. In electrochemical corrosion conditions, the zinc layer as the anode will give priority to the reaction, even if the galvanized layer of local damage, but also to continue to provide protection for the wire, this “sacrifice of self, to protect others,” the characteristics of iron wire coated with zinc more durable.
Secondly, the galvanized layer gives the wire a brighter appearance. After galvanized treatment, the surface of the wire shows a dazzling metallic luster, which enhances the overall visual aesthetics, and is widely used in the field of decoration and handicraft production.
Furthermore, the galvanized layer also enhances the mechanical properties of iron wire. It not only improves the hardness and abrasion resistance of the wire, reducing the wear and tear in daily use, but also reduces defects by optimizing the surface structure of the wire, indirectly improving the overall strength, making the wire more durable.
To sum up, the galvanized layer plays an irreplaceable role in preventing corrosion, beautifying the appearance and enhancing mechanical properties, which makes iron wire coated with zinc widely used in many fields
