How to Prevent Corrosion in TMT Bars?

What is corrosion?
Corrosion is the process in which a material deteriorates as a result of its interaction with its environment.
Corrosion is the primary cause of metal deterioration.
Corrosion occurs in refined metals as they want to return to their stable form. Many metals or alloys undergo corrosion from exposure to water or air.
However, this process can also be facilitated by exposure to other substances.

Here are 5 ways that will help you prevent corrosion on your TMT bars:

1.    Avoid Exposure to Corrosive Agents

Prevent the deterioration of metals by limiting its contact with corrosive agents.
For instance, safeguard the metal materials from rainwater or excessive moisture by properly storing it indoors.
Moreover, exposure to substances containing chloride (such as salt water) must be limited.
Instead, treat the feed water inside the water boilers with softener to prevent corrosion.

2.    Proper Monitoring of Metal Surface
Carefully monitor the metal surface. Look for cracks and crevices.
These manufacturing flaws can also lead to corrosion.
Moreover, use corrosion-resistant products. For example, if you are buying TMT bars for construction, choose corrosion-resistant bars.
Corrosion-resistant TMT bars ensure the longevity of the structure.

3.    Prevent Galvanic Corrosion
 
When two different metals come in contact with each other in an electrolyte, one metal acts as anode and the other as cathode.
The presence of an electrolyte acts as a conduit for ion migration, moving metallic ions from the anode to the cathode.
This leads to the anode metal corroding more quickly while the cathode corrodes slowly, thus resulting in Galvanic corrosion.
Such type of corrosion is common to gas or oil pipelines, or the hull of the ships and boats.
To prevent galvanic corrosion, apply a protective coating on the metal surface. This prevents the electrolytes from facilitating ion flow between the metals.
Providing cathodic protection by using a sacrificial metal anode in the electrolytic environment also protects the metals.

4.    Protect the Metal Surface

 
Paints can be used to protect the metal surface from corrosion.
The paint forms a protective barrier between the metal surface and the corrosive agent.
For instance, coating the outdoor metal units with a coat of paint protects them from exposure to rainwater or snowfall etc. A number of solutions such as galvanized zinc coating, paint, or oil sealant can be used to prevent corrosion.
5.    Metallic Plating

Metallic plating can also be applied to prevent corrosion.
Common processes of metallic plating include electroplating (covering the surface with a layer of tin or nickel), mechanical plating (applying zinc or cadmium to the metal surface), Electroless (coating with cobalt or nickel), or hot dipping (immersing the metal in molten zinc).
