Ir–Ta Stability where oxygen is the target reaction. | Lower oxygen-evolution overpotentialThe IrO2-based catalytic surface promotes oxygen evolution and can reduce the anode contribution to cell voltage when the coating is correctly matched to the process. Stability in acidic oxygen-evolving serviceIrO2 provides electrocatalytic activity, while Ta2O5 stabilizes the coating structure for demanding oxygen-evolution conditions. Extended operating lifeApplication-matched formulation, controlled titanium preparation and multilayer thermal treatment are engineered to slow coating deactivation and extend service intervals under compatible operating conditions. Consistent coating uniformityControlled application and repeated thermal conversion support even catalytic coverage across the active area, helping maintain stable current distribution and repeatable electrode performance. |

Designed around your electrolyte.There is no universal oxygen-evolution anode. YIANTENG reviews the dominant reaction and operating window before defining coating, active area and electrode construction. | Operating-condition review and coating recommendationYIANTENG reviews electrolyte composition, acidity, chloride and fluoride content, temperature, current density and target service life before recommending coating formulation and loading. Custom electrode design and fabricationPlate, mesh, tube, active area, current connection and complete electrode assemblies can be manufactured to customer drawings and installation requirements. Controlled coating productionTitanium preparation, multilayer coating and thermal treatment are controlled within one manufacturing workflow to support adhesion, coating uniformity and batch consistency. Inspection, documentation and recoating supportYIANTENG can define project-specific inspection and documentation, and evaluate suitable used titanium substrates for coating removal, condition inspection and recoating. |

Ir–Ta or Ru–Ir? | Ir–Ta based MMO coatings are generally selected when oxygen evolution is the dominant anodic reaction, particularly in acidic or chloride-poor electrolytes. For chloride-rich processes where chlorine evolution or active-chlorine generation is the objective, a Ru–Ir based coating may be more appropriate. Final selection should be based on the complete electrolyte composition and operating conditions. |
