What factors affect the service life of titanium anodes?

Sep 13, 2024

1. Current density: The current density is inversely proportional to the anode lifetime. The higher the current, the shorter the anode lifespan.


2. Titanium substrate: The anode substrate is generally pure titanium, and the required material is above TA1. If the purity of the substrate is not sufficient, the corrosion resistance will be greatly reduced, which has a significant impact on the service life of the anode.


3. Electrolyte: The electrolyte must not contain fluoride ions, cyanide ions, and sulfur ions, as they can significantly affect the lifespan of the anode.

4. Inverted electrode: Inverted electrode is a commonly used method in anode repair, used to separate passivated old coatings from the substrate surface. Therefore, it is strictly prohibited to reach the electric poles in use.


5. Frequent power outages: Without current passing through the plating solution, prolonged power outages can cause significant damage to the plating solution.


6. Human damage: The surface of the titanium anode should not have any hard damage. If some of the coating is damaged, even small scratches, it will quickly corrode and passivate the
anode, ultimately leading to failure.
