Hear from our students

Now we can control the Anodizing process through more accurate methods

The greatest thing about the course was the huge amount of specific and complete information about metallurgy and the possible impacts in the layer quality.

Because of that, we are now able to increase even more the quality of our products.

The course definitely has given us the opportunity to learn new anodizing methods and new ways to control this process in a more accurate and specific method. I was concerned that the course could be shallow, and that it would not increase my company's knowledge in anodizing. Happily, this fear did not come to be a reality, since the course brought us a vast amount of information, and that made our background on the subject even larger.

I would recommend the course to all anodizers that seek to or need to improve their processes. Beyond that, to anyone who searches for technical, profound and didactic information about anodizing.

I got all the little details right when setting up our first Anodizing Line

The masterclass gave me a safe introduction to setting up our first anodizing line. Making sure we didn't miss any important details, getting the correct equipment and not overspending at our first attempt in anodizing.

It's been a pleasure working with Anne.

Despite heavy Anodizing experience, David learned a lot from Anodizing Masterclass

At Hydro, our expertise is aluminum, so some of the material wasn’t “new” to me. My experience is heavy with 6000 series alloys and light with 3000 and 7000 alloys.

I enjoyed learning about the nature of all the other series. Even with my knowledge, I still thought it was worth watching.

We do a lot of corrosion testing here, especially, lately, for IGC resistance. And while I understand what is happening, sometimes I still have a hard time wrapping my mind around the order that the mechanisms proceed in.

I especially liked how you expanded on the differences between acidic and alkaline corrosion, the creation of corrosion products, etc. And I liked your discussions of the different types of corrosion and the influences that alloying elements have on corrosion.

It has been useful to me and will be useful in my job at Hydro.
