Zinc plating is an electroplating technique in which components are placed in an electrolytic bath containing an electrolyte and an electric current enters the bath to promote the build-up of the zinc onto the component. One of the unique properties of zinc plating is that it is a sacrificial coating, meaning it will continue to protect a components surface even if the coating becomes scratched and bare metal is exposed. Zinc electroplating is the traditional plating used for industrial corrosion protection. The outer surface of the zinc coating corrodes to form zinc oxide, which provides an additional physical barrier against air and water to protect against rust. In addition to being used as a functional protective coating, zinc plating can also be used as a decorative coating. The zinc coating after passivation treatment can obtain various colors to increase the decorative effect. There are many types of zinc plating additives, including acid zinc additives, alkaline zinc additives, alkaline cyanide-free zinc additives, etc. These additives play an important role in the zinc plating process, which mainly stems from the fact that they help to improve the properties of the plating.
With the help of additives, zinc plating offers many advantages. The main advantages are as follows.
Improve the corrosion resistance of your components.
Increase the lifetime of the steel.
Enhance aesthetic appeal of the components.
Suitable for either barrel or rack plating.
Enhance adhesion and ductility of components.
Operates within a wide range of bath chemistry.
With the aid of additives, zinc plating has been useful in many fields. The main applications are as follows.
Zinc plating has many benefits, but it does not work for every condition. The main precautions are as follows.
Avoid using zinc electroplating for seawater or marine applications or in any tropical environment because they can contribute to forming heavy corrosion.
When you expose the steel parts are at a temperature level of 500 degrees Fahrenheit or more, you should avoid using zinc.
Don't use zinc plating on equipment or products that you can ordinarily keep in closed areas where there is heavy moisture condensation.
