Di Noer Platinized Titanium Mesh Anode – Custom Coating & Shape for Electroplating

Among various anode types available for electroplating and electrochemical processes, the platinized titanium mesh anode remains one of the most widely selected. Its popularity comes down to practical, real-world performance: strong ionization release, good electrolyte exchange, a compact structure, and low weight.

Di Noer Technology Co., Ltd. manufactures platinum-coated titanium mesh anodes that can be shaped according to each customer's specific plating bath size and operating conditions. Common configurations include plates, meshes, rods, wires, and tubular forms.

In addition, Di Noer has developed its own patented formula for titanium anode coatings. This allows the anode service life to be pre-designed by adjusting the noble metal coating formulation based on the customer's actual service conditions. Anode dimensions and coating thickness are both customizable.

Product Comparison – Platinized Titanium Anode (PTA) vs MMO

Parameter	Platinized Titanium Anode (PTA)	MMO
pH range	1.0 – 12.0	1.0 – 12.0
Pt / mixed oxide layer thickness (µm)	0 – 10.0 (customizable up to 20 µm)	8.0
Max fluoride content	50 mg/L	50 mg/L
Max allowable current	50 A/dm²	50 A/dm²

Platinum coating thickness can go up to 20 µm for applications requiring longer life or harsher conditions.

Key Features

Platinized titanium anodes combine the excellent electrochemical performance of platinum with the high corrosion resistance of titanium. Compared with soluble electrodes or traditional lead anodes, they offer several clear advantages.

Flexibility to meet various needs
Different plating baths require different anode geometries and coating thicknesses. Di Noer can adjust both.

Ability to produce complex shapes
Mesh, rod, wire, tubular, and custom profiles are all available.

Energy saving
Lower cell voltage compared to many conventional anodes.

Light weight
This is especially noticeable with mesh grid anodes, which are easier to handle and install.

Longer working life under high current density
The platinum coating and titanium substrate withstand aggressive conditions.

Firm structure, less deformation
Titanium provides mechanical strength that holds its shape over years of use.

Second platinizing allowed
When the original coating eventually wears down, the anode can be re-coated, extending its total service life.

Uniform deposit for high-quality final products
Consistent current distribution leads to better plating results.

Shapes Available

The titanium substrate can be manufactured in the following forms:

Mesh grid

Plate

Rod

Wire

Tubular

Custom shapes are also available upon request.

Coating Thickness

Standard platinum coating thickness ranges from 0 to 10 µm. For more demanding conditions or longer expected life, thickness can be increased up to 20 µm.

Quality & Customization

Di Noer operates under ISO 9001:2015 certified processes. Each production step – from titanium substrate selection and surface preparation to coating application and final inspection – is controlled by our QA/QC department.

Because the anode life can be pre-designed, customers are encouraged to share their typical operating parameters (current density, electrolyte composition, temperature, and required service life). Di Noer will then recommend or formulate a coating that matches those conditions.
