A: A ruthenium-iridium titanium anode uses Gr1/Gr2 titanium as the substrate, coated with a catalytic coating whose core active components are noble metal oxides such as ruthenium and iridium. Simply put, DSA and MMO anodes are general terms for this type of anode. The ruthenium-iridium titanium anode is the most widely used and has the best overall performance. It is specifically optimized for operating conditions dominated by chlorine evolution reactions and is currently the mainstream anode material in the electrochemical field.

A: Standard type: 3-5 years. Ultra-thick coating long-life type: 5-10 years. Cathodic protection type: 15-30 years. The anode’s lifespan is mainly affected by the following factors:

Parameters: Current density, operating temperature, electrolyte composition, pH value, presence of reverse current, etc. Higher current density, higher temperature, stronger acidity, and presence of reverse current will shorten the lifespan accordingly.

Coating precious metal loading: Higher loading results in longer lifespan. We design a reasonable precious metal loading based on your expected lifespan.

Coating formulation and technology: Gradient structure coatings have a longer lifespan than ordinary uniform coatings. Wstitanium’s unique gradient coating technology can increase lifespan by more than 100%.

A: The standard range for the noble metal (Ru+Ir) loading of a ruthenium-iridium-titanium anode is 5 g/m² to 30 g/m². It is designed based on operating conditions and expected lifespan:

Mild operating conditions, short-term use: 5-10 g/m²; Normal operating conditions, 3-5 year lifespan: 10-20 g/m²; Extreme operating conditions, over 5 years lifespan: 20-30 g/m².

It is important to note that a higher noble metal loading is not always better. Excessive loading can increase internal stress in the coating, reduce adhesion, and easily lead to peeling and cracking. It also significantly increases costs. WSTITANIUM will design the optimal noble metal loading based on your operating conditions and expected lifespan, controlling costs and achieving the highest cost-effectiveness while ensuring a long service life.

A: The standard pH range for ruthenium-iridium-titanium anodes is 1-12. Different pH environments have a certain impact on the performance and lifespan of the anode:

Neutral, weakly acidic, and weakly alkaline environments (pH=3-11): This is the optimal operating range for ruthenium-iridium-titanium anodes, resulting in the most stable performance and the longest lifespan.

Strongly acidic environments (pH<3): It is necessary to increase the IrO₂ content to improve the corrosion resistance of the coating. Our high-iridium modified ruthenium-iridium-titanium anodes operate stably in strongly acidic environments for extended periods.

Strongly alkaline environments (pH>11): It is necessary to optimize the coating formulation to prevent the coating from dissolving in strongly alkaline environments. We have ruthenium-iridium-titanium anode formulations specifically optimized for strongly alkaline environments. WSTITANIUM can customize a coating formulation according to your electrolyte pH value to ensure stable operation and long service life of the anode.

A: The maximum operating temperature of WSTITANIUM standard ruthenium-iridium-titanium anodes is 60℃. Specialized ruthenium-iridium-titanium anodes optimized for high-temperature conditions can operate stably for extended periods at temperatures up to 95℃. Higher operating temperatures accelerate coating dissolution and shorten service life. If your operating temperature exceeds 60℃, we will optimize your coating formulation by increasing the content of IrO₂ and stabilizers.

A: The standard operating current density range for WSTITANIUM ruthenium-iridium-titanium anodes is 100-5000 A/m². Specialized anodes optimized for high current density applications can operate stably at current densities up to 10000 A/m².

Higher current densities result in faster electrochemical reactions at the anode. This also accelerates coating wear and shortens the anode’s lifespan. If your application requires high current densities, we can optimize the coating formulation to increase the precious metal loading.

A: It is not recommended to use ruthenium-iridium-titanium anodes for long-term reverse current supply. Short-term, occasional reverse current supply is tolerable, but long-term reverse current supply will cause serious damage to the anode.

When reverse current is supplied, the ruthenium-iridium-titanium anode becomes the cathode. A large amount of hydrogen gas is generated on its surface. This hydrogen gas permeates to the interface between the coating and the titanium substrate, causing the coating to blister and peel off. Simultaneously, hydrogenation occurs on the surface of the titanium substrate, forming titanium hydride, which leads to embrittlement of the titanium substrate and ultimately anode failure.

If your operating conditions involve reverse current, such as pulse power supplies in electroplating or power outages during electrolysis, WSTITANIUM can customize ruthenium-iridium-titanium anodes specifically designed to withstand reverse current.

A: The main reasons for coating peeling off on ruthenium-iridium-titanium anodes are as follows, and the corresponding avoidance methods are as follows:

Reason 1: Inadequate pretreatment of the titanium substrate. If the oxide layer and oil stains on the surface are not completely removed, the adhesion between the coating and the substrate will be poor, making it easy to peel off.

Avoidance: WSTITANIUM employs a 5-step core pretreatment technology. Strict control of parameters at each step ensures that the adhesion between the coating and the substrate is ≥20MPa.

Reason 2: Improper coating sintering. Inappropriate sintering temperature and holding time lead to a lack of strong metallurgical bonding between the coating and the substrate, resulting in high internal stress and easy peeling.

Avoidance: Wstitanium uses gradient sintering. Each layer undergoes rigorous low-temperature drying and high-temperature sintering to form a strong metallurgical bond. At the same time, the gradient structure design alleviates the internal stress of the coating, preventing coating peeling.

Reason 3: During installation, disassembly, and cleaning, scraping or bumping the coating with hard objects can cause mechanical damage and peeling.

Prevention: Protect the coating during installation, disassembly, and cleaning. Do not scrape or bump the coating with hard objects, and do not use hard tools such as wire brushes to clean it.

Reason 4: Prolonged reverse current flow can cause the coating to bulge and peel off.

Prevention: Avoid prolonged reverse current flow as much as possible. If reverse current is present in the operating conditions, choose our reverse current resistant anode.

Reason 5: Operating conditions exceed the anode’s applicable range, such as excessively high temperature, excessive acidity, or excessive current density, leading to rapid corrosion and peeling of the coating.

Prevention: Select a suitable anode based on the operating conditions. WSTITANIUM will customize a custom anode solution for you, perfectly suited to your operating conditions, to avoid this problem.

A: The price of ruthenium-iridium-titanium anodes is mainly calculated based on a combination of factors, including the anode’s surface area, precious metal loading, coating formulation, substrate structure, processing difficulty, and order quantity.

Anode Surface Area: The core basis for price calculation. The larger the surface area, the more raw materials used, and the higher the price.

Precious Metal Loading: Precious metals (Ru, Ir) are the core cost of the anode. The higher the loading, the higher the price.

Coating Formulation: Different coating formulations have different proportions of precious metals, resulting in different prices. High-iridium formulations are more expensive than standard formulations.

Substrate Structure: Standard plate and mesh structures are less expensive, while tubular, irregular, and complex structures are more expensive.

Order Quantity: Larger batches result in lower prices. Scale production reduces unit costs.

Real-Time Precious Metal Prices: The market prices of precious metals such as ruthenium and iridium fluctuate, affecting the price of anodes. WSTITANIUM has its own precious metal coating solution preparation workshop. The price is 10-20% lower than similar products in the industry, while the performance is superior.

A: To judge the quality of ruthenium-iridium-titanium anodes, the following core indicators are key. These are also the items that WSTITANIUM rigorously tests for every product.

**Coating Composition and Precious Metal Loading:** Does the composition ratio of the coating meet the design requirements? Does the precious metal loading meet the standards? Is the error within a reasonable range? These are the core indicators determining anode performance and lifespan, and can be verified through ICP testing.

**Electrochemical Performance:** Chlorine evolution overpotential, oxygen evolution overpotential, current efficiency, and cyclic voltammetry active surface area. The lower the overpotential, the larger the active surface area, the better the catalytic activity, and the lower the energy consumption.

**Accelerated Life Test Time:** This is the core indicator for evaluating anode lifespan. Tested according to GB/T 20929 standards, the longer the accelerated life time, the longer the actual lifespan. A high-quality anode should have an accelerated life time ≥ 60 minutes.

**Coating Adhesion:** The higher the adhesion between the coating and the titanium substrate, the better. High-quality anodic adhesion should be ≥20MPa to ensure the coating does not peel off. Verification is achieved through pull-out tests, scratch tests, and bending tests.

Coating Thickness and Uniformity: The coating thickness must meet design requirements, and uniformity must be good, with no pinholes, cracks, or missed areas. This can be verified using an eddy current thickness gauge and scanning electron microscope (SEM).

Appearance and Dimensions: The appearance must be uniform and dense, without runs, peeling, or flaking. Dimensions must conform to drawing requirements, and processing accuracy must meet standards.

Every WSTITANIUM product undergoes testing for all of the above indicators, and all indicators meet or exceed national standards, guaranteeing product quality and performance.
