One of the most common and essential components present in metal buildings are metal fasteners. There are two types of Metallic fasteners – both permanent and releasable. Some of the examples of these fasteners include nut-bolts, metal screws, clamps, rivets, rings, couplers, and pins.
Talking about metallic objects like steel fasteners, the primary threat associated with them is corrosion. This can be detrimental to metallic fasteners because it can damage their build, appearance, and bonding strength, leading to compromised structural integrity. You may want to know how to prevent metal fasteners corrosion, and we are happily here to help you better understand that.
Let’s begin with understanding corrosion. It is the most common problem that occurs in metals or any metallic object.
Corrosion is the term used for the electrochemical reaction that occurs in metallic objects. When the metal ions collide with moisture or air particles, the electrochemical tension between the moisture droplets and metal ions ultimately leads to the dissolution of the metal ions.
The result is the development of a layer of oxide hydrate, or rust, on the surface of the metal objects. Many types of corrosion happen due to the different factors involved, such as the metal type, surface type, and exposure type.
The following are the significant types of corrosion;
The first step towards the treatment of any issue is to have proper knowledge of the cause. The primary reason for metallic fasteners failure is fastener corrosion. Now, let’s understand what causes metal fastener corrosion.
Usually, metallic fasteners are attached to other metallic objects. This is the first step that makes the pins prone to corrosion. The next thing that plays a significant role in triggering deterioration is the electric potential of the connected metals.
As moisture gets in contact with the two different metallic surfaces, the water ions react differently. This is the electric potential tension between the two metals that leads to creating a galvanic cell. In this cell, a low-energy electric current starts flowing from one metal to another, or from higher to lower electrical potential metal.
When the electric potential of fasteners is higher than the other metal, the above phenomenon occurs. The outflow or electric current or electrons from the high potential metal fastener represents the loss of ions. As a result, rusting takes place over the lost electron layer, and the metal fastener is called corroded.
Let’s also go over what happens when the metal fasteners begin to corrode;
Though fasteners can undergo any type of corrosion, they are most prone to Galvanic Corrosion. This is a type of corrosion that occurs when two different types of metals are involved. Galvanic corrosion represents the electrochemical reaction that occurs upon the contact of two or more potentially different metal types.
When two metals are placed in close proximity to each other, they begin exchanging electrons. This flow of electrons takes place from higher potential metal (anode) to lower potential metal (cathode). Thus, the higher potential metal eventually starts losing electrons, which also tantamount to corrosion of the metal. The ion loss leads to the metal becoming weaker and degraded.
Galvanic corrosion can happen even if the two metals are indirectly connected. Things like conductive electrolytes can help the breakdown to occur too. The intensity of galvanization is also directly proportional to the difference in the electric potential of the metals in contact.
Now that you understand the essential details of metal fastener corrosion, let’s give you some valuable tips on how to prevent it:
Remember that the fasteners will eventually rust and degrade. However, you can delay that process with the help of the proper preventive measures and care. It is always better to take the first step right. On that note, the best option is to only buy the best fasteners that are tested to be corrosion-proof.
