Product features:
Platinum coated titanium electrode as anode material has four main characteristics:
1. High corrosion resistance, durability and high temperature resistance, high stability, can be used in a variety of media;
2. Lower cost than pure gold and platinum anodes, but have similar electrochemical properties;

3. High overpotential for oxygen release reaction and low overpotential for hydrogen release reaction;
4. High output current density, uniform conductivity, low loss, suitable for DSA insoluble anodes.
How to use Platinum-coated titanium electrode?
1. Before using the platinum coated titanium electrode, you should first exclude (must test) whether the "chloride" ion and "phosphate" ion exist in the plating solution, to confirm that there is no corrosion of the chemical composition of the platinum coated titanium electrode, before the safe use of platinum coated titanium electrode.
Otherwise, the base material at the bottom of the platinum coated titanium electrode will be seriously corroded, the platinum coating will fall off and the service life will be shortened, do not casually use the hard inscription additive and the recycling industrial inscription pastry containing chloride ions.
2. Reasonable choice of the best process: platinum coated titanium electrode current density is best selected below 50A/dm2, tank pressure below 10V, otherwise affect the service life of the anode will cause serious galvanic corrosion, dissolution, plating off, try to choose the anodic oxidation reaction without solid oxide generation process,
Avoid oxide thickening passivation affect the conductivity of platinum coated titanium electrode. Anode breakdown is based on titanium itself characteristics, when tank pressure is bigger than 10V, titanium surface coated with the platinum begins to slightly dissolve,
After the breakdown, we can no longer see the trough pressure of 12V, only about 11V, the current can not be added, the anode is destroyed, so set the safe use of platinum coated titanium electrode trough pressure below 10V.
3. Normally, cathode surface area should be smaller than that of anode(area under the liquid surface), titanium electrode can't be used when the anode area is smaller than the cathode area, because anode will be easily broken through.
4. Tank pressure will increase with increasing of plating tank impedance. When the tank pressure exceeds 10V, you should not continue to increase the current, but should adjust the current appropriately, such as: adjusting the current downward by 10%, and extending the plating time by 10%.
