Zinc is widely used for coating steel due to its excellent corrosion resistance properties, particularly under normal atmospheric conditions. The protective mechanism involves the formation of a zinc oxide layer that acts as a barrier against further corrosion. Additionally, zinc serves as a sacrificial anode, corroding preferentially to protect the underlying metal, which is particularly beneficial in marine environments where electrolysis is a concern. This dual functionality makes zinc an ideal choice for steel protection in various applications.
PREREQUISITESEngineers, materials scientists, and professionals involved in metal fabrication and corrosion prevention will benefit from this discussion, particularly those focused on steel protection strategies.
supasupa said:Why Zinc is so commonly use coat metals such as steel? I know that its a good corrosion resistant metal to use but what properties of zinc make it good to use under normal atmospheric conditions?
Does it have to do with the oxide layer that it forms around it?
