Anodizing titanium is a great way to add a unique and stylish look to your metal jewellery or components. Anodizing involves submerging the titanium in an acid electrolyte solution and passing an electric current through it, which creates a layer of oxidation on the metal that gives it a unique colour. In this article, we’ll cover the basics of anodizing titanium black.
Basics of Anodizing Titanium Black
Anodizing titanium black is actually quite simple—all you need are some basic supplies, such as an acid electrolyte solution, a battery charger, and a container for the solution. Here’s how it works:
Prepare the Solution
The first step is to prepare the solution by mixing one part water with two parts sulfuric acid in your container (make sure you use protective gloves and eye protection when handling sulfuric acid). This mixture is what will be used as the electrolyte for your anodizing process.
Submerge Your Titanium
Once your solution is ready, submerge your piece of titanium into it. Make sure that all surfaces of the titanium are completely submerged in order to ensure even coverage during the anodization process.
Attach Clamps
You’ll need to attach clamps to each end of your piece of titanium so that they can be connected to a battery charger. This will create a circuit that sends power through your piece of titanium while it’s submerged in the electrolyte solution, allowing oxidation to occur on its surface.
Apply Voltage
Now that everything is connected properly, turn on your battery charger and set it to 12 volts DC (using any voltage higher than 12 volts could potentially damage or warp your piece). The current should flow for about 10 minutes; if you want darker results, you can increase this time up to 20 minutes or more (note that increasing voltage beyond 12V could potentially damage or warp your piece).
Rinse and Dry
Once you’ve reached the desired shade for your piece (keep in mind that colours may appear slightly lighter once dry), remove it from the electrolyte solution and rinse it thoroughly with clean water before drying with a soft cloth or paper towel.
Conclusion:
Anodizing titanium black is relatively easy if you have access to the right supplies and know-how! By following these steps—preparing your electrolyte solution, submerging your titanium piece in it, connecting clamps to each end of the piece, applying voltage via a battery charger set at 12 volts DC, rinsing off residual electrolytes after 10-20 minutes (or longer depending on desired colour), then drying—you should have no problem achieving beautiful results! With enough practice and patience, you’ll soon be able to make all kinds of beautiful pieces out of anodized black titanium! Good luck!
