What does the corrosion process involve in a tool? What products and solutions can we use to prevent this attack? To begin with, when a tool has a rusty appearance, what it is indicating is that maintenance is conspicuous by its absence.
Why do tools rust?
Not all metals are susceptible to oxidation, since they do not react to humidity or oxygen in the atmosphere – this is the case with gold or platinum – but the reality is that most tools rust. And they do so because they are made with elements that, when in contact with a corrosive agent such as salt water, humidity, oxygen or certain corrosive chemicals, oxidize. These elements usually have construction steel or iron in their composition.
Iron and moisture: natural enemies
What does the corrosion process involve in a tool? Hammers, pliers, wrenches or tweezers made of ferrous materials, if we forget them outside after a rainy night, have an opaque surface. And they do it in a few hours. This matte appearance is an oxide layer that protects the ferrous metal from rust.
Of course, if it’s a dazzling day but there is some humidity, the tools are also not spared from rust, which, when water intervenes or in humid conditions, accelerates.
Yes, rust manifests itself mainly in humid environments. However, there are other elements that cause corrosion. For example:
- Salt: this increases the conductivity of the aqueous solution formed on the metal surface and intensifies the rate of electrochemical erosion.
- Heat: The higher the temperature, the higher the rate of corrosion.
What is rust and how to avoid it?
Surely on more than one occasion you have taken your old toolbox out of the garage and you have observed that characteristic orange-brown color. Well, that unsightly layer is hydrated iron oxide, or what is the same, rust, which appears after a very complex process that begins with the oxidation of iron to iron ions. These ions, once oxygen and water intervene, are oxidized to form ferric ions.
To prevent this degradation, there are coatings (usually urethane or epoxy) that protect metal surfaces against corrosive attacks, but also against chemical or abrasive elements.
