1. Before using platinum-plated titanium electrode, you should first exclude (must test) whether there are "chloride" ions and "phosphate" ions in the plating solution, to confirm that the chemical composition of platinum plating does not corrode the titanium electrode, before the safe use of platinum-plated titanium electrode.
Otherwise, the base material at the bottom of the platinum plated titanium electrode will be seriously corroded, the platinum plating layer will fall off, and the service life will be shortened. Do not use hard inscription additives and recycled industrial inscription pastries containing chlorine ions at will.
2. Reasonable choice of the best process: platinum titanium electrode plating current density is best to choose 50A/dm2 or less, tank pressure of 10V or less, otherwise affect the anode life will cause serious galvanic corrosion, dissolution, plating off, try to choose no solid oxide generation process of anodic oxidation reaction.
Avoid oxide thickening passivation affect the conductivity of platinum-plated titanium electrodes. Anode breakdown is based on the properties of titanium itself, when the trough pressure is greater than 10V, the platinum-plated titanium surface begins to dissolve slightly.
You will get efficient and thoughtful service from GIANT ANODE.
After breakdown, you can't see the valley pressure of 12V, only about 11V, you can't add current, and the anode is destroyed, so the safe use valley pressure of platinum-plated titanium electrode is set below 10V.
3. Generally, the surface area of cathode should be smaller than anode (area below the liquid surface), when the area of anode is smaller than the area of cathode, titanium electrode cannot be used, because the anode is easy to be broken through.
4. The tank pressure will increase with the increase of impedance of plating tank. 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%.
