Corrosion is a problem when it comes to metal. Once your masterpiece is exposed to the elements, eventually rust or corrosion will set in, so this is something you are going to have to take into consideration. Thinking about corrosion before it becomes a problem is often a good strategy.
There are a few different types of corrosion you could run into. Check out what they are and how to prevent them:
The first, and most common type, is uniform corrosion. This type of corrosion has a reddish color that covers your fastener. The way to prevent uniform corrosion is to choose the right plating and coating option for your project.
Another type of corrosion is called galvanic corrosion. Galvanic corrosion occurs when two different metals are electrically connected through a conductive solution. This can be prevented by using metals with similar corrosion potentials, by insulating or separating the materials from each other, or by applying coatings to both materials.
Crevice corrosion occurs in any small cracks or crevices in a fastener. These spaces have the possibility of retaining moisture, which can lead to corrosion. To prevent this from happening, you will want to use washers sparsely and try to make sure all joint surfaces are as smooth as possible, so as not to create spaces for crevice corrosion to occur.
This type of corrosion consists of holes that penetrate inward in a certain area of material. It often occurs because the surface is exposed to chemicals. To prevent pitting corrosion, choose a material that is most appropriate for the conditions it will be in.
Stress Corrosion Cracking
Stress corrosion cracking occurs when the materials are subject to tensile stress and a corrosive environment. In order to prevent stress corrosion cracking, try to reduce the stress being put on your materials, and choose your materials wisely.
Those are many of the types of corrosion. Before putting together your next project consider this list to reduce the risk of corrosion. If you have any questions, contact us at ProvenProductivity@bossard.com.
