Which is better galvanising or tinning?
galvanising :)
You can use zinc to stop things rusting how do you do that?
Galvanising is the act of coating a metal (iron or steel) in a thin layer of zinc. The metal is dipped in molten zinc.
What are some examples of finishes for metals?
Anodising, Plating, Powder Coating and Galvanising
What does rusting need?
For something to rust you need oxygen and water. Rust specifically relates to iron (or iron products such as steel); it is iron oxide. When the metal comes into contact with oxygen disolved in water the iron in the metal reacts with the oxygen disolved in the water to form iron oxide - rust. This is why most metals are protected, to stop water and oxygen getting into contact with the metal and causing corrosion i.e. rust. Common methods of protection include galvanising, painting and coating.
How is the composition of metal changed if it rusts?
Rust is the oxidation of iron.Metals will react with oxygen but only iron'rusts'.Aluminium oxidises but it forms an impermeable oxide layer on the aluminum which prevents further oxidation.Zinc has a stronger affinity for oxygen than iron. Zinc is used to coat iron in a process known as galvanising. The zinc oxidises preventing the iron from rusting. The zinc actually forces the iron to keep its electrons rather than losing them to oxygen.2Fe(s) + 3O2(g) --> 2Fe2O3(s)2Zn(s) + O2(g) --> 2ZnO(s)When iron and zinc are together:Zn(s) + Fe2+ --> Zn2+ + Fe(s)
What is the metal used for galvanising iron?
It is the element zinc in its molten state that we dip iron or steel into to galvanize it.
How does galvanising protect iron form corrosion?
Because it prevents water from touching the surface of the iron.
Which is better galvanising or tinning?
galvanising :)
How do you prevent corrosion?
Rusting of iron can be prevented by painting,oiling,greasing,galvanising,chrome plating,anodising or making alloys
Why is galvanising used?
God could you people just put the correct answer!

Galvanising is the act of coating a metal (iron or steel) in a thin layer of zinc. The metal is dipped in molten zinc.
What is the powder on galvanising?
Zinc.
What metal do you use to protect steel from corroding?
There are several metals which can help protect iron from rusting. The iron is electroplated with a non-corrosive metal such as aluminum, copper, zinc, or titanium.
Tips on preventing rust?
Galvanising or painting both prevent iron from rusting. Painting is less expensive but also less permanent and the treatment needs to be repeated as the paint flakes off.
How do you protect steel from rust?
It can be protected by galvanising its surface with Zinc.
What has the author William Highfield Jones written?
William Highfield Jones has written: 'Story of the Japan, tin-plate working, and iron braziers' trades, bicycle and galvanising trades, and enamelware manufacture in Wolverhampton and district'
How are silver plates put on teaspoons?
They are usually done with a form of galvanising.
