The metal surface is not allowed to come in contact with moisture, O2 and CO2. i) Coating the metal surface with paint.
ii) Applying oil or grease. iii) Electroplating with non-corroding metals like Ni, Cr, Al, Sn, Zn.
iv) Coating with alkaline phosphate (anti rust) solution.
Sacrificial protectionCovering the surface with a more electro positive metal than Fe. The more electro positive metal loses electrons and as long as this coating is present Fe is protected. Example:
Galvanization - Covering with zinc. The zinc also forms a protective coating of ZnCO3.Zn(OH)2.
Electrical protection (Cathodic protection)The iron object is connected to a more active metal either directly or through a wire. Fe acts as the cathode. The more reactive metal is the anode. It loses electrons and gradually disappears. Example: Fe can be connected to Mg, Zn or Al which are called the sacrificial anodes. Used for protecting under ground pipes from rusting.

How can I prevent my garden tools from rusting?
To prevent garden tools from rusting, keep them clean and dry after use, store them in a dry place, and apply a light coat of oil or rust-resistant spray regularly.
How can rusting of objects be prevented?
Rusting of objects can be prevented by using protective coatings such as paint, oil, or galvanization to create a barrier between the object and oxygen and moisture in the air. Keeping objects dry, storing them in a low-humidity environment, and using desiccants can also help prevent rusting. Regular maintenance, such as cleaning and lubricating, can further protect objects from rust.
Which metal prevent the rusting of iron?
Stainless steel, which contains chromium, nickel, and other elements, is commonly used to prevent the rusting of iron. The chromium in stainless steel forms a protective oxide layer on the surface of the metal that helps to prevent corrosion.
How can I prevent my bike chain from rusting?
To prevent your bike chain from rusting, regularly clean and lubricate it with a bike-specific lubricant. Store your bike in a dry place and avoid riding in wet conditions whenever possible.
What conditions encourage rusting?
Rusting requires conditions such as moisture and air (oxygen).
What kind of metal can survive underwater conditions?

How do you prevent a car body from rusting?
Painting will be a good option to prevent rusting.
What are the conditions necessary for rusting?
The conditions necessary for rusting are water (or water vapour) and air, specifically Oxygen. If one condition is absent and the other is present then rusting would not occur but if both are present then rusting will occur
How does coating iron prevent rusting?
Coating prevent the iron from contacting air and moisture. So it prevents iron from rusting.
Does oil help prevent iron from rusting?
no it just oils it+++ It will for a time but oil loses its efficacy as a protective fairly quickly, depending on conditions.

What are conditions required for rusting?
MOISTURE AND OXYGEN
Why is my bike rusting and how can I prevent it?
Your bike is rusting because of exposure to moisture and oxygen, which causes the metal to oxidize. To prevent rust, you can regularly clean and dry your bike, apply a protective coating like wax or oil, store it in a dry place, and avoid leaving it outside in wet conditions for extended periods.
Does varnish prevent rusting if so how why What about butter again how why?
Varnish can help prevent rusting by acting as a protective barrier that prevents moisture and oxygen from reaching the metal surface. Butter does not prevent rusting because it does not form a barrier to protect the metal. Instead, butter is likely to attract moisture and potentially accelerate the rusting process.
