Electroplating( Au,Ag, Pd);
Platinum Plated Titanium Anode combines the excellent electrochemical performance of Platinum and higher anticorrosion property. Comparing with the other soluble electrode and Lead anode, it has the following advantages.
Flexibility to meet various using needs;
Produce complex shape of anode;
Light weight (especially the mesh grid anode);
Longer working life under higher current density;
Firm titanium structure, less deformation;
Second platinized allowed;
Uniform deposit, final products with high quality.
Shapes:Shapes of the titanium based substrate mesh grid anode, plating anode, rod anode, wire and tubular anode.
Thickness:The platinum coating is 0-20µm, it could be up to 20µm with higher requirements.
Lifespan: The expected life platinized anode is based on the working media (electrolyte), and the anode current density which should be less than 75A/dm2, it has small abrasion under this current density to estimate the anode working life. According to the experience, in the Chromium electroplating solution with fluorine free, the abrasion of platinum coating is 1-4g every one million ampere hour. When the current density is above 75A/dm2 or using the electroplating solution with fluorine, the platinized niobium anode recommended (see platinized niobium anode).
