What chemicals protect the surface of metals? Corrosion inhibitors are chemicals that react with the surface of the metal or the surrounding gases to suppress the electrochemical reactions leading to corrosion. They work by being applied to the surface of a metal where they form a protective film.
How can we prevent metal from rusting?
Galvanizing applies a protective coating of zinc over iron or steel. Since zinc corrodes about 30 times slower than iron, galvanizing can be a cheap and effective way to prevent rust. Like all of the ways to prevent rust, galvanizing has limitations.

Then simply wipe it off with a soft cloth. … Just spray it on, let it sit for a few seconds, and wipe it off with a cloth.
What can speed up rusting?
Salt water is an electrolyte which conducts ions, speeding up rusting. No rust. Calcium chloride dries out the air. Salt solution acts as an electrolyte (any substance containing free ions that allows the substance to conduct electricity) allowing iron to lose electrons more easily and so speeds up the rusting process.
Which metal is used for galvanizing?
Galvanisation or galvanization (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc.
