katooditud

Katooditud refers to a process of applying a protective or decorative coating to a metal surface using an electrochemical method. This technique involves immersing the metal object, which acts as the cathode, into an electrolyte solution containing ions of the coating material. A direct current is then passed through the solution, causing the metal ions to deposit onto the cathode. This results in a thin, uniform layer that adheres strongly to the base metal.

The term "katooditud" specifically highlights the role of the object as the cathode in this electrochemical deposition process. This method is widely used in various industries. For instance, it's employed in electroplating to add layers of materials like zinc, nickel, or chromium for corrosion resistance and aesthetic appeal. It is also used in anodizing, particularly for aluminum, where the metal surface is intentionally oxidized to form a thicker, protective oxide layer that can then be dyed or sealed. The precise control over current density, voltage, and electrolyte composition allows for tailored coating properties.
