How Is The Blackening Process Performed For Hydrogen Embrittlement Prevention?

Metal can be weakened by a variety of different things, such as physical force and acid. You might not be aware that atomic and molecular hydrogen can also cause the metal to become brittle and weaken. This can cause problems for tools and equipment that have metal coatings or are made of metal.

The corrosion occurs when hydrogen is trapped on the surface of the metal. This is where the blackening process is so useful because it stops the hydrogen from being trapped on the surface. Therefore, the corrosion rate of the metal is going to drop significantly. When the corrosion rate drops, the metal is going to stay in a very good condition rather than becoming damaged by the corrosive elements.

There is a simple solution to this problem, and it is called blackening. A fine coating is applied by Blackfast to the metal in order to ensure that atomic or molecular hydrogen can no longer cause any problems for the metal that is being affected.

Hydrogen embrittlement is prevented by blackening. How is the blackening process performed for hydrogen embrittlement prevention?

  1. The Metal Is Cleaned Before Blackening
  • Prior to the blackening process, the metal needs to be thoroughly cleaned. When a metal is clean it is going to have much more resistance to hydrogen than when it was not clean. Spray cleaning and alkaline detergent are just two of the methods that can be used to ensure that the Once the cleaning process has been completed, it is time to move onto the next stage of the process.
  1. The Metal Is Rinsed With Clean Water
  • Once the metal has been cleaned, it will then be rinsed with clean water to make sure that all of the cleaning fluids have been successfully removed. This is done in an environment which is free of contamination. Once the metal has been properly rinsed, the next phase of the process can begin.
  1. The Metal Surface Is Activated
  • Metal needs to be active in order for the blackening process to be successful. The activation process is designed to remove the oxides and to balance the PH level of the acid. Once the activation process has been completed, it is time for the next phase to begin.
  1. The Metal Is Given The Second Rinsing
  • Another rinsing is performed before the blackening can be performed.
  1. The Blackening Process Is Carried Out
  • The blackening process is carried out, where a coating is applied to the surface of the metal. This is going to make the surface of the metal much more resistant to hydrogen embrittlement.
  1. The Metal Is Given The Third Rinsing
  • Rinsing is performed again to remove residue from the blackening process.
  1. Sealant Is Applied To The Metal
  • The sealant is applied to the metal in order to stop humidity from affecting the metal.


Hydrogen embrittlement prevention is going to be possible thanks to the blackening process.
