Electroplating – what is galvanizing?
Galvanizing is a type of electroplating process, where a layer of metal, typically zinc, is applied to the surface of steel or iron. The process is done by using an electric current to move metal ions from an electrolyte solution to the metal part, which acts as the cathode. The electroplating process creates a protective layer of metal that adheres tightly to the base material. This layer of metal acts as a barrier, preventing moisture and air from reaching the surface of the steel, resulting in corrosion resistance.

Galvanizing is often used on metal parts that are exposed to weather, such as fences, pipes, or structural components. In addition to corrosion protection, galvanizing can also enhance the electrical conductivity and appearance of the metal. The benefits of electroplating include not only corrosion resistance but also increased hardness and wear resistance.
What is electroplating?
The process of electroplating begins with cleaning the metal part to remove any dirt or impurities from its surface. The part is then immersed in a bath containing a zinc electrolyte solution. An electric current is passed through the solution, causing zinc to deposit onto the surface of the metal, forming a thin layer. This is done by moving the metal part to the cathode, where it attracts zinc from the solution. The anode supplies the zinc needed for the plating, and the current density must be carefully controlled to ensure even coating.
The layer of zinc bonds well to the surface of the metal, ensuring that the metal is protected for many years. On the other hand, if the zinc layer is too thin, it may not provide adequate protection against rust. Galvanizing metal can also be done using barrel plating or other methods, depending on the size and shape of the parts being treated.
Galvanizing is commonly applied to metal such as steel, ensuring its durability and protection. This process enhances the formation of a strong zinc coating on the surface of parts, providing excellent corrosion resistance.
Applications of galvanizing
Galvanizing is used in a range of industries due to its corrosion protection properties. For example, it is frequently used in electrical components where a durable and conductive surface is required. The electroplating is used on everything from construction materials to car parts. For example, a thin layer of gold may be used in electronic parts for its excellent conductivity and resistance to corrosion. Galvanizing can also be used on plastic parts to enhance their surface properties.
