Prevention of corrosion 7 point

1.	Prevention of corrosion 7 point
Answer» Following methods can be used to prevent corrosion:\tGalvanisation: Method to protect steel and iron articles from rusting by coating them with a thin layer of zinc.\tAlloying: Homogeneous mixture of two or more metals, or a metal and a non-metal to change the properties of the pure state metals and protect them from rust.\tFor instance, Iron is used widely for different purposes but it is never used in pure state. It is due to the fact that pure iron is very soft and stretches in hot state. But mixing with small amount of carbon (about 0.05%) makes it strong and tough. Mixing nickel and chromium with iron gives stainless steel, which is hard and does not rust.
