ANODIC COATING Meaning and
Definition
-
Anodic coating refers to a type of protective coating that is applied to metal surfaces through a process called anodization. It is commonly used to enhance the resistance of the metal object against corrosion, wear, and surface damage.
During the anodization process, the metal object (usually aluminum or titanium) is submerged in an electrolyte solution and connected to the positive terminal (anode) of a direct current power supply. The metal acts as an anode and oxygen ions from the electrolyte combine with the metal atoms, forming a layer of oxide on the surface of the object. This oxide layer is what creates the anodic coating.
The thickness and properties of the anodic coating can be controlled by adjusting factors such as voltage, temperature, and duration of the anodization process. This allows for customization according to the desired application and requirements.
Anodic coatings possess several desirable characteristics. They offer increased hardness and durability, providing excellent abrasion resistance. Additionally, the coating is highly corrosion-resistant, protecting the metal surface from environmental factors. Furthermore, anodic coatings can be dyed or sealed, improving their aesthetic appearance and further enhancing their resistance properties.
Common applications of anodic coating include architectural elements, automotive parts, aerospace components, and electrical equipment. It is a versatile and highly effective technique in increasing the lifespan and performance of metal objects.

Etymology of ANODIC COATING
The word "anodic" originates from the Greek prefix "ano-" meaning "up" or "away from", combined with the word "odein" which means "to go". "Coating" is derived from the Middle English word "coten", which means "to cover".
Therefore, the term "anodic coating" refers to a coating that is applied by an anodizing process, where metal is immersed in an electrolyte and subjected to an electric current. The positive electrode in this process is known as the anode, hence the use of the term "anodic" to describe the type of coating formed during the process.
