Titanium Wire Anode For Chrome Plating

Titanium wire anodes are widely used in chrome plating electrochemical systems, where they serve as stable, corrosion-resistant positive electrodes. The anodes are manufactured using Gr1 titanium wire as the substrate, coated with either Iridium-Tantalum (Ir-Ta MMO coating) or Platinum (Pt coating) depending on the electrolyte system and process requirements.

These coatings are applied through multi-layer brushing + high-temperature sintering (Ir-Ta) or electroplating (Pt) to ensure strong adhesion and long-term stability.

Coating Types

Iridium–Tantalum (Ir/Ta MMO Coating)

Mixed metal oxide coating (IrO₂ + Ta₂O₅ system)

Produced via repeated brushing and thermal decomposition

Excellent stability in acidic and oxidizing environments

Platinum Coated Titanium (Pt/Ti)

Platinum layer deposited on titanium wire surface via electroplating

High electrocatalytic activity and conductivity

Suitable for high-performance plating systems

Chrome Plating Working Principle

In the chromium plating process:

Titanium wire anode acts as the positive electrode (anode)

Workpiece acts as the cathode

Electrolyte contains chromium ions

Under DC current:

Chromium ions are reduced and deposited on the cathode surface

A uniform chromium coating is formed

Key Advantages

Excellent Corrosion Resistance
Ir-Ta coating resists strong acidic chrome plating environments

High Electrocatalytic Efficiency
Pt coating improves current efficiency and plating stability

Long Service Life
Strong adhesion between coating and titanium substrate ensures durability

Low Contamination Risk
No dissolution of base metal into electrolyte → maintains bath purity

Stable Performance
Suitable for continuous industrial chrome plating production
