A deep dive into the anodizing tank

In this course we demistify the "magical" chemistry of anodizing

Oftentimes, anodizing is seen as making aluminum thicker and corrosion-resistant. While this is true, anodizing is much more than that. Anodizing allows changing surface properties, making the aluminum product more versatile, durable, and aesthetically appealing. In other words, anodizing is not a necessary evil; it is a value proposition.

Suggested time to complete this module: 2 hours of learning, up to a week or more of planning, trying & creating your optimal and well documented anodizing process step

How to anodize

Building an oxide layer is more than just putting the aluminum into the anodizing tank. You have an entire suite of tools available to you in this module, and you can leverage them to engage your customers and improve their anodizing skills and anodized parts.

This module will cover everything about the formation of aluminum oxide you need to know in order to create a unique anodized aluminum product.

What this module will cover:

  • What to ask your customers
  • Setting demands to your customer about the aluminum alloy
  • What anodizing entails and how it has been done successfully already
  • How to play with various anodizing parameters
  • How to build a proper and high-quality anodic layer
  • Troubleshooting defects
  • Why current is better to use than voltage if you want to do better than practice
  • What is best practice when anodizing different aluminum alloys

Anne Deacon Juhl

My name is Anne Deacon and I have worked in the anodizing industry for more than 25 years. My anodizing journey started when I wrote my Ph.D. thesis as a research scientist at the Technical University of Denmark about "Pulse Anodizing of Extruded and Cast Aluminum Alloys".

After finishing my Ph.D. I worked with anodizing both as an independent consultant and as a supervisor and quality manager in anodizing companies. Thus, I have great experience with different kinds of chemical and electrochemical surface treatments, such as chromating, electroplating, electroless plating - Anodizing – type I, II, and III are my favorites.

What I am most passionate about is the sustainable aspect of aluminum anodizing. I strongly believe anodizing is the most efficient and sustainable solution for anodizing aluminum. This conviction has also led to my decision to create AnodizingSchool where I seek to enhance knowledge about anodizing in the world.
