The difference between electroplating sealed and unsealed

Electroplating is a surface treatment method that deposits metal ions onto the surface of an object through chemical reactions. In the electroplating process, if a layer of organic polymer film is coated on the surface, it is called electroplating sealing, otherwise it is not sealing.

I、 What are electroplated sealed and unsealed

Electroplating is a surface treatment method that deposits metal ions onto the surface of an object through chemical reactions. In the electroplating process, if a layer of organic polymer film is coated on the surface, it is called electroplating sealing, otherwise it is not sealing.

II、 The difference between electroplating sealed and unsealed

1. Corrosion resistance

Electroplating sealing can improve the corrosion resistance of electroplated parts, as organic polymer films can cover the metal surface, providing isolation, protection, and slowing down electrochemical reactions.

However, unsealed electroplating cannot improve corrosion resistance because the metal surface is exposed to air and moisture, which can easily react chemically with oxygen and water, leading to problems such as rust and corrosion on the surface of the electroplated parts.

2. Corrosion resistance

The metal surface enclosed by electroplating is isolated from the outside world and is not easily corroded by corrosive gases or chemicals in the environment, so its corrosion resistance is also good.

Metal surfaces that are not sealed for electroplating are susceptible to corrosion, leading to a decrease in surface quality and a shortened lifespan.

3. Appearance effect

Electroplating sealing generally makes the surface of electroplated parts smoother and smoother, and the color can also be more vibrant and beautiful.

Unrestricted electroplating may result in surface defects such as unevenness, bubbles, and bumps.

III、 Summary

In summary, the difference between electroplating sealed and unsealed lies in anti-corrosion, corrosion resistance, appearance effect, and other aspects. If you want to achieve better electroplating results, it is recommended to choose closed electroplating.
