1. Current density: the current density is inversely proportional to the anode life. The greater the current, the shorter the anode life
2. Anode base material: The anode base material is typically pure titanium, and it must be greater than the TA1 material. If the purity of the base material used is not enough, the corrosion resistance will be greatly reduced, which has a great impact on the service life of the anode.
3. Electrolyte: It is prohibited to contain fluoride ions, cyano ions and sulfur ions in the electrolyte, if any, it will also have a great impact on the life of the anode.
4. Reverse electrode: the reverse electrode is a method often used in anode repair, which can make the old passivating coating fall off from the substrate surface. Therefore, it is prohibited to reach the electrode in use.
5. Frequent power-off: under the condition of no current, the coating will be greatly damaged if it is immersed in the solution for a long time.
6. Artificial damage: The anode surface shall be free of hard damage. If some coatings are damaged, even a small scratch will cause rapid corrosion/passivation of the anode and finally lead to failure.
7. Contacting the cathode or the anode when the power is on is prohibited. Because of the short circuit's extremely high instantaneous current, the electrode plate risk being burned.
