Factors Affecting The Electroplating Process

Electroplating is one of the most important processes that are always in demand in the metal and manufacturing units or industries. But have you given a thought as to why this process has become so popular? We all make use of metallic objects and wish them to stay strong and sturdy for a long period.

This can be possible with the help of the electroplating process. The Electroplating process is known to provide a protective layer on the surface of the objects and even strengthen them and prevent corrosion. With these amazing features, it has become understandable that each and every metal or manufacturing industry is looking forward to embracing it.

What Do You Mean By Electroplating Process?

The electroplating process basically refers to developing a layer (through deposition) of metallic substance on the surface of the objects electrically. The object on which the metallic deposition is done can be either a metal or a non-metal, and this is helpful in providing strength to the objects and making them durable. The electroplating process is referred to by different names, such as electroforming, electro-metallic deposition, electro-facing.

In order to make sure that the electroplating process goes perfectly well, you need to consider all the factors that have a great effect on the electroplating process. So what are those important factors that have an effect on the electroplating process?

#1 The Electrolyte Nature That Is Used In The Process

In the process of electroplating, the deposit is formed by a smooth layer above the object. But the level of the smoothness is dependent on the nature of the electrolyte. For instance, if the process makes use of the cyanide electrolytes then, you can observe that the smoothness would be high because of the presence of complex electrons or ions.

#2 The Density Of The Deposition Is One Of The Major Factor

In the process of electroplating, the rate of the electrode deposition will entirely depend on the rate at which the crystals of the electrode deposit grow, the current density, and how the nuclei get formed.

So based on current density (either it’s low or high), the final appearance of the deposition would be decided. The low current deposit would form a coarse and crystalline layer. Whereas if the current density is high, the layer would be smooth and sleek. If the current dentist is extremely high, then the layer would become porous and spongy.

#3 The Temperature At Which The Process Takes Place

Temperature also plays an important role in deciding the final results of the electroplating. If the temperature is quite low, the solution formed due to the presence of the electrodes will lead to the formation of the small crystals of the metallic substance. But if the temperature is high, you could observe that the crystal formed is extremely large in size.

There are many benefits of having a high temperature during the process:

• It helps in increasing the solubility of the salts in the solution.
• It helps in increasing the concentration of the metals and supports higher current densities.
• It improves the conductivity of the metallic objects so that the layer sticks to the surface and bonds perfectly.
• Higher temperature also helps in decreasing the occlusion of hydrogen in the deposited layer of metal.

#4 The Electroplating Process Is Also Dependent On The Conductivity Factor

A solution that has good conductivity is quite important for the electroplating process. It will be helpful in facilitating less power consumption and also beneficial in reducing the formation of trees in the rough deposits. This will ensure that the final product would be quite smooth and perfect.

Summary

Well, now you know what are the important factors that affect the electroplating process. But these are generalized factors. There are some specific factors that are known to have an impact on different types of electroplating processes.

Every technician must keep in mind the important factors before they initiate the electroplating process. This will ensure that the process works out well and the final product is perfect. You can visit the Noble Metal company website to know more about the types of the electroplating process.
