MMO Disc Anode for Localized Cathodic Protection

MMO Disc Anode Engineering

Compact Active Surface for Localized Current Output

MMO disc anodes are selected when a compact, plate-like active surface is required for localized cathodic protection or small electrochemical systems. They are commonly reviewed for concrete repair, marine structures, compact treatment units, pilot systems, laboratory cells, and custom equipment where space, shape, and mounting method matter.

Compared with tubular or rod anodes, MMO disc anodes provide a flat active surface that can be mounted against or near a defined protection area. Compared with wire or ribbon anodes, disc anodes are more suitable for localized current output rather than long-area distributed current layouts. Hele Titanium supports custom MMO disc anodes with round, elliptical, oval, or drawing-based shapes, single-side or double-side coating, mounting holes, cable connections, threaded structures, packing, labels, and documentation according to project requirements.

What Is an MMO Disc Anode?

An MMO disc anode is a titanium disc, plate, or shaped titanium substrate coated with mixed metal oxide. It is used as a compact anode where a defined active surface is needed for localized cathodic protection, electrochemical reaction, testing, or custom equipment integration.

MMO disc anodes can be manufactured in round, elliptical, oval, or special shapes. Depending on the application, the coating can be applied to one side, both sides, or a defined active area. The correct disc size, coating area, mounting method, and connection design should be reviewed according to current output, operating environment, installation space, and design life target.

Active Area, Coating Side and Current Output Must Be Reviewed Together

For MMO disc anodes, the physical shape is only one part of the design. Active surface area, single-side or double-side coating, current density, operating environment, mounting direction, and connection design all affect the final recommendation.

01

Active Surface Area

Affects the available current output and should match the protection area or cell design.

02

Coating Side

Single-side, double-side, or partial coating should be selected according to installation direction and reaction zone.

03

Current Density

Current density should be reviewed to avoid unsuitable loading or premature coating stress based on operating conditions.

04

Mounting & Connection

Mounting holes, cable sealing, tabs, and electrical continuity are important for compact installations.

Installation Considerations for MMO Disc Anodes

Proper installation helps MMO disc anodes deliver localized current output more effectively. Disc placement, active side direction, mounting method, contact environment, cable routing, and mechanical protection should be reviewed before installation.

Installation Factor	Why It Matters
Disc Placement	Affects localized current output and protection coverage.
Active Side Direction	Single-side coated disc anodes must be oriented correctly toward the target reaction or protection zone.
Mounting Method	Bolted, embedded, fixture-mounted, or custom mounting should match site or equipment design.
Contact Environment	Concrete, seawater, electrolyte, or other conductive environments affect current transfer.
Cable Routing	Proper routing helps protect cable insulation and maintain electrical continuity.
Cable Sealing Protection	Sealing quality is important for wet, embedded, or high-exposure environments.
Mechanical Protection	Helps reduce damage during handling, installation, operation, or equipment maintenance.
Inspection Access	Useful for future system review, testing, and maintenance planning.

Buyer Note: MMO disc anode installation should be reviewed together with the full cathodic protection or electrochemical system design. Share your layout, current requirement, coating side requirement, and installation method for engineering review.

MMO Disc Anode FAQ

What is an MMO disc anode? +

An MMO disc anode is a titanium disc or plate-like substrate coated with mixed metal oxide. It provides a compact, defined active surface designed for localized cathodic protection or small electrochemical systems.

Where are MMO disc anodes commonly used? +

They are commonly used in localized cathodic protection, reinforced concrete repair zones, marine structures, compact electrochemical cells, laboratory testing systems, and custom electrochemical equipment where space is limited.

What is the difference between round, oval, and elliptical MMO disc anodes? +

Round discs provide a symmetrical active area. Oval and elliptical shapes are used when a longer or narrower active surface is needed to fit specific installation spaces, such as embedded concrete slots or specific marine structural profiles.

What is the difference between MMO disc anode and MMO tubular anode? +

A disc anode provides a flat, plate-like localized current output, ideal for surface mounting or compact spaces. A tubular anode provides cylindrical, omnidirectional current output, typically used in deep wells, groundbeds, or open water environments.

What is the difference between MMO disc anode and MMO rod anode? +

A disc anode is flat and suited for mounting against surfaces or providing a localized wide face area. A rod anode is a solid cylinder, better suited for insertion into tanks, pipes, or probe assemblies.

Can MMO disc anodes be coated on one side only? +

Yes. Single-side coating is common when the anode is mounted flat against a non-conductive surface, ensuring current is directed only towards the protected structure or reaction zone. Double-side coating is also available based on project needs.

How do I choose disc size and active area? +

Disc size and active area should be reviewed according to the required current output, operating environment, allowed current density, and the physical space available for installation.

Can you customize mounting holes and cable connections? +

Yes. We can support custom mounting holes, threaded connections, welded tabs, and specific cable lengths and types according to your equipment design or installation layout.

Can MMO disc anodes be used for localized concrete CP? +

Yes, disc or oval anodes can be embedded in specific concrete repair zones to provide localized impressed current cathodic protection to reinforcing steel.

Can MMO disc anodes be used in laboratory or pilot electrochemical cells? +

Yes. The defined flat active area makes them highly suitable for compact laboratory test cells and pilot reactors where precise current control over a specific area is needed.

What documents can be provided? +

We can provide Mill Test Certificates (MTC), coating records, dimensional inspection notes, packing lists, and other project-specific documents when required and agreed upon during quotation.

What information is needed for a quote? +

Please provide the application, operating environment, required current output, design life target, preferred disc shape/size, coating side preference, mounting method, cable requirements, and quantity.
