Anodizing Titanium for Implant Parts.
Anodizing titanium is an electrochemical surface treatment.
- This operation modifies the oxide layer of the metal to change its properties.
- Anodizing refers to the electrolytic formation of an oxide layer on the surface of a metal.
Controlled oxidation creates a coating that changes the mechanical properties of titanium.
- Anodizing increases resistance to corrosion and wear:
- Provides electrical insulation.
- Improves absorption of dyes for coloring.
Cleaning and pretreatment of the anodizing operation of titanium:
First it is essential to clean the titanium part.
- Immerse the part in an alkaline bath to remove any dirt, grease or oxide residue.
- This cleaning operation is crucial because any residual contaminants can interfere with the anodizing process.
- After cleaning, the part is thoroughly washed with a demineralized water bath.
Placement of the implant on the electrolytic bath support:
- The cleaned titanium part is positioned on the support.
- The support is connected to the red positive terminal of the device.
- The support is then immersed in an electrolyte bath (600 ml of water with 20 g of baking soda)
- This electrolytic solution allows the circulation of current which activates the electrochemical process of anodization.
Control the voltage, current, temperature:
The thickness of the oxide layer and, therefore, the resulting color are dictated by the voltage, current and temperature at the during the process.
- Higher voltages produce thicker layers and different colors.
- Careful regulation of these parameters is essential to achieve the desired results, making this step a true exercise in precision.
- Choose the desired color by increasing or decreasing the current.
- Finally, once the anodizing is complete, the titanium part is thoroughly rinsed to remove any lingering electrolytes.
The anodizing of the titanium has an impressive range of benefits.
Anodizing: Resistance to corrosion and wear.
The anodizing process forms an incredibly durable oxide layer on the surface of the titanium.
This layer is much harder than the underlying titanium, providing excellent resistance to wear and corrosion.
- Anodized titanium is non-toxic and biocompatible, making it an ideal choice for applications dental.
- Anodized titanium implants, prostheses and surgical instruments are widely used in the medical field due to their compatibility with the human body and resistance to body fluids.
Anodized titanium technical data:
- The coloring process lasts only 5 seconds.
Different shades will be obtained depending on the voltage.
- Water containing sodium bicarbonate can be used as electrolyte.
- At 60 V, a nice golden tint is obtained, very popular in the dental sector.
The titanium anodizer is a simple device that allows you to treat titanium dental elements quickly, easily and economically.
- The results are comparable to products in a much higher category.
- Anodizing is an electrochemical process that creates a protective layer of oxide on the surface of the metal, in our case titanium.
- This layer called anodic layer is thicker than the natural oxide layer that forms on titanium when exposed to air, which offers many advantages: anodizer for titanium.
- The anodic layer protects titanium from corrosion, even in adverse conditions (use in mouth).
- The anodic layer is harder than the base titanium, making it more resistant to frictional wear.
- Any overlay of another material (e.g. zirconium) will be easier to attach to the anodized base element (titanium).
The titanium oxide layer minimizes the release of metal ions into the physiological environment.
The anodic layer can be colored with different shades, giving the titanium a more attractive appearance than the original taupe.
This advantage is particularly interesting in the case where the anodized element serves as a support for a translucent material, for example zirconium.
