What are the main factors affecting the service life of titanium anodes
1. Current density: The current density is inversely proportional to the life of the anode, the greater the current, the shorter the life of the anode.
2. Titanium substrate: The substrate of the anode is generally pure titanium, 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 will have a great impact on the service life of the anode.
3. Electrolyte: It is forbidden to contain fluoride ion, cyanide ion and sulfur ion in the electrolyte, if there is, it will have a great influence on the life of the anode.
4. Inverting: Inverting is a method often used in anode repair, which can make the old passivated coating peel off from the surface of the substrate. Therefore, it is forbidden to use it to the extreme.
5. Frequent power outages: In the absence of current flow, the coating will be greatly damaged by prolonged immersion in the solution.
6. Man-made damage: There should be no hard scratches on the surface of the anode. If part of the coating is damaged, even a small scratch will cause the anode to be rapidly corroded and passivated, eventually leading to failure.
