What Gold Electroplating Is Best for Your Project?

Electroplating is the process of using an electric current to deposit material. Therefore, gold electroplating is using the electric current to deposit gold. It creates a thin layer of gold on the surface of the material called a substrate.

This process helps create an aesthetically appealing look as well as increase resistance to wear and tear. This process also gives objects protection from corrosion and increases their thickness.

Engineering Requirements

Gold electroplating dates back as early as the 18th century. The process has since advanced but remains one of the most trusted in the community. Gold is a noble metal. This means that it does not oxidize or chemically react under most normal conditions. It is the prime material to prevent corrosion.
It also has excellent electrical and thermal conductivity. If you are an engineer, you will know that it meets most engineering requirements due to these properties.

Soft vs. Hard Gold

Gold electrodeposits come in one of two forms: “soft” and “hard” gold. Hard gold plating is most often used in areas where there is a connection. For example, if you have an object that slides or makes contact with another item, hard gold plating prevents wear and tear better than soft gold plating.

Soft gold plating is commonly used in areas where there is a higher temperature or stronger risk of corrosion. As stated previously, gold is a noble metal. Therefore, at a higher temperature, it is less likely to be oxidized in comparison with other metals such as nickel, copper, tin, zinc, and palladium.
