What are the main factors that affect the service life of titanium anodes?

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

2. Titanium substrate: Pure titanium is generally used as the anode substrate, and it is required to be above TA1 material. If the purity of the substrate used is not enough, the corrosion resistance will be greatly reduced, which has a significant impact on the service life of the anode.

3. Electrolyte: Fluoride ions, cyanide ions, and sulfur ions are prohibited from being present in the electrolyte, as they can have a significant impact on the lifespan of the anode.

4. Inversion: Inversion is a common method used during anode repair, which can cause the old passivation coating to detach from the surface of the substrate. Therefore, it is prohibited to use it.

5. Frequent power outage: In the absence of current flow, prolonged soaking of the coating in solution can cause significant damage.

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

7. Short circuit: It is prohibited to make contact between the anode and cathode when powered on. The instantaneous current caused by a short circuit is very large and can burn out the electrode plate
