Anodizing Titanium With A Power Supply - TekPower TP12001X (2021)

Introduction

This tutorial will guide you through the process of anodizing titanium using a DC power supply, specifically the TekPower TP12001X. Anodizing enhances the appearance and durability of titanium, allowing you to achieve various colors, including the sought-after green finish. Whether you're working on knife scales or jewelry, following these steps will help you master the anodizing process.

Step 1: Gather Your Materials

Before you begin anodizing, ensure you have all the necessary supplies:

• DC Power Supply: TekPower TP12001X (0-120V)
• Whink Rust & Stain Remover: For cleaning titanium surfaces
• Alligator Clip Test Leads: For connections
• 28 Gauge Titanium Wire: To attach your titanium piece
• Baking Soda: Acts as an electrolyte
• Distilled Water: For creating the anodizing bath
• 9V Batteries: Optional for powering the setup

Tips

• Use distilled water to prevent impurities affecting the anodizing process.
• Ensure your titanium piece is clean and free of oils or contaminants.

Step 2: Prepare the Anodizing Bath

Create an effective anodizing bath using the following steps:

1. Mix Electrolyte Solution:

   • Combine distilled water and baking soda in a container.
   • A common ratio is 1 tablespoon of baking soda per quart of water.

2. Set Up Your Container:

   • Use a non-metallic container to hold your electrolyte solution.
   • Ensure it is large enough to immerse your titanium piece fully.

Practical Advice

• Stir the mixture well to ensure the baking soda is fully dissolved.
• If you're aiming for specific colors, adjust the voltage accordingly during the anodizing process.

Step 3: Connect the Power Supply

Set up your power supply and connections:

1. Attach Alligator Clips:

   • Connect one clip to the positive terminal (anodizing).
   • Attach another clip to the titanium piece using the titanium wire.

2. Set Voltage on Power Supply:

   • Start at a low voltage (around 20V) and gradually increase.
   • For the green color, target around 45-50V.

Common Pitfalls

• Avoid setting the voltage too high initially; this can lead to uneven coloring or damage to the titanium surface.

Step 4: Anodize the Titanium

Begin the anodizing process:

1. Immerse the Titanium Piece:

   • Place your connected titanium piece into the electrolyte solution.
   • Ensure it is fully submerged.

2. Monitor the Process:

   • Watch for color change; this typically takes a few minutes.
   • Adjust the voltage as needed based on the desired color outcome.

Tips for Success

• Keep the area well-ventilated and wear protective gear.
• Use a timer to keep track of how long you've been anodizing for consistent results.

Step 5: Rinse and Inspect

After achieving the desired color:

1. Remove from Bath:

   • Carefully take out the titanium piece from the solution.

2. Rinse:

   • Rinse the piece in distilled water to stop the anodizing process.
   • Pat dry with a soft cloth.

3. Inspect the Finish:

   • Check for uniformity in color and make sure there are no imperfections.

Final Touches

• If needed, you can re-anodize to achieve a more vibrant color or fix any uneven areas.

Conclusion

Anodizing titanium can be a rewarding DIY project, allowing you to customize your metal pieces with a range of colors. By following these steps, you'll be able to effectively anodize titanium using a DC power supply. Remember to experiment with different voltages to achieve various colors and finishes. As you gain more experience, you can refine your technique and explore more complex anodizing designs. Happy anodizing!
