Learn everything about anodizing pretreatment

This e-learning course is module #5 in the Anodizing Masterclass.

By enrolling in this e-learning course with a focus on anodizing pretreatment, you learn how the pretreatment phase will make or break your finished aluminum surface and what pitfalls to avoid.

What to expect from "Anodizing pretreatment"

This module will teach you a proven strategy for creating a uniform and well-prepared surface before entering into the anodizing step.

There is no one-size-fits-all magic solution here - but with some basic knowledge about surface chemistry, you will be able to create your own best practice.

By the end of the module, you will get some hands-on tips for troubleshooting the different pretreatment steps.

Suggested time to complete this module: 1,5 hours.

What this module will cover:

  • What to do when we want to create a high-quality surface for the anodic coating
  • How do we know when the surface is ready
  • What happens in the degreasing step
  • How to create a super unique surface by etching
  • What is the difference between desmut and deoxidizing
  • How to polish your aluminum surface to achieve a mirror-like appearance
  • What influences the reflectivity of the coating
  • How to stay focused and find the most common pretreatment failures

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.
