Question

how does galvastion prevent rusting





​

Answer 1

Rusting of iron can be prevented by painting, oiling , greasing , galvanising , chrome plating , anodising or making alloys.

• Galvanisation is a method of protection steel and iron from rusting by coating them with a thin layer of zinc. It cuts the contact of water and oxygen from the metal's surface . The galvanised article is protected against rusting even if the zinc coating is broken .

Answer 2

• Rust protection is accomplished through galvanizing.
• Zinc is applied in a thin coating to the iron or steel item.
• The zinc functions as a sacrificial metal, preventing oxygen and water from accessing the metal beneath.
• Because zinc is more reactive than iron, it oxidizes faster than iron.
• Galvanization is the process of covering iron with a protective zinc coating to prevent corrosion.
• Iron is protected from rusting by the zinc coating, which prevents it from coming into contact with air and moisture.
