What is sacrificial coating?
When a more reactive metal sacrifices itself for a less reactive metal to prevent the lesser reactive metal from rusting. :-)
Which metal prevent the rusting of iron?
zinc prevents rusting of iron by the process galvanisation
Is ordinairy nails an alloy?
Normally nails aren't made of an alloy however they are galvanized, this means they have a coating of a less reactive metal such as Zinc as to prevent rusting of the nails. Nails are normally made out of iron.
How are metals treated to prevent them from rusting?
Metals are prevented from rusting by providing a coating on the surface of the metal to stop the metal from mixing with oxygen and H2O in the air. Please do not copy this word for word. I am handing this in for a report. Thanks!
How do you stop metal rusting in salt water?
To prevent metal from rusting in saltwater, you can apply a protective coating such as paint, oil, or a corrosion-resistant metal coating like zinc or stainless steel. Regular cleaning and drying are important to remove salt residue and prevent corrosion. Additionally, using sacrificial anodes or cathodic protection can provide an extra layer of protection by redirecting corrosion to sacrificial metals.

Kinds of metal in building a ship?
Usually steel or Aluminum but special paint and coating should be applied to prevent rusting from the water.
How does electro-plating work?
Electroplating is the coating of a reactive metal with a less reactive metal. This allows the reactive metal take longer to corrode. E.G.: Coating steel or iron with gold or silver
Which metal is non reactive?
Aluminium is non reactive as it forms a coating of Al2O3.

Three ways to prevent rust?
Ways to protect metal from corrosion: 1. Galvanisation is method of protecting steel & iron from rusting by coating them with a thin layer of zinc. The galvanised article is protected against rusting even if the zinc coating is broken. 2. Painting, greasing & oiling are some commonly used methods to prevent rusting. 3. Chrome plating, anodising & making alloys are some other ways to prevent corrosion of metals.
Stop metal rusting?
Provide a coating to the surface of the metal either a permenant or temporary. For a permenant coating, apply a paint or lacquer formula For a temporary coating, apply either oil, wax or pollish, which you will have to replenish often
What happens when coating on zinc or iron metal gets cracked or damaged?
The zinc coating no longer protects the underlying metal from rusting, once water and air gets through the crack.
How does tin plating prevent rusting?
Tin itself is highly resistant to rusting (oxidation) so the tin coating remains intact. Oxygen molecules are therefore unable to reach the iron layer beneath, making it impossible for the iron to rust.
