What if it rusts?

To remove rust, remove it with various tools, or dissolve it in an acidic solution. After removing the rust, be sure to treat the surface of the iron, coated with a layer of lead, and then painted; Or plated with other metals that don't rust easily. A more thorough method is to add some other metals to the iron to make an alloy that does not rust. Stainless steel, as we know it, is an alloy made by adding a little nickel and chromium to steel.

How to prevent rust?

(1) to form an alloy to change the internal structure of the iron. For example, chromium, nickel and other metals into ordinary steel to make stainless steel, it greatly increases the rust resistance of steel products.

(2) coating on the surface of iron products is a common and important way to prevent iron products from rusting. According to the composition of the protective coating, it can be divided into the following categories:

The surface of iron products is coated with mineral oil, paint or fired enamel, plastic spray, etc. For example: the carriage, the bucket and so often painted; Machines are often coated with mineral oils and so on.

A layer of non-rusting metal, such as zinc, tin, chromium, nickel, etc. These metal surface can form a dense oxide film, thus preventing iron products and water, air and other substances in contact with rust.

A dense and stable oxide film is formed on the surface of iron products to prevent them from rusting.

(3) keeping the surface of iron products clean and dry is also a good way to prevent iron products from rusting.
