Scanning electron microscope

Firstly, characterization.

Let's go back to our SEM image.

Once we've captured this image with our microscope, we now want to go to every single pixel in the image and allocate it to a particular material.

Is it active material? Is it poor? As you can imagine, that's an extremely arduous task.

I can then take those vectors and pass them to a classifier in combination with a bit of human expertise and generate a very accurate and very fast map of the distribution of phases inside my material.

The next thing that AI is helping with, generation.

Let's go back to our beautiful SEM image.

We've segmented it.

We wanted to understand how these two variables worked together to control corrosion protection rather than studying either zinc loading or coating thickness in isolation.

We combined a mixture design statistical modeling with electrochemical impedance spectroscopy, EIS, polarization-resistant measurements, open-circuit potential monitoring, and cross-sectional SEM EDS analysis.

This allowed us to relate coating formulation and thickness to both the electrochemical performance and the physical consumption and redistribution of zinc particles during exposure.

The most exciting result was that thicker coatings were not always better at approximately 80% of zinc.

Because

I saw the, oh no, I was thinking of a different Nile Red Exeter where you were like taking apart the SEM.

Yeah, that's on the Extra channel, yeah.

I just had

an idea.

Yeah, there's an SEM part too.

If you can't...

That's when we stripped it down to nothing.

A lot of what we do is measurement based.

Um, we do have, uh, an SEM, which is a scanning electron microscope, uh, which allows us to zoom in very, very close to, um, any sort of foreign particles.

So one of the things that, that a lot of professional engine builders, you know, find very helpful is when we, when we see debris or we have a debris issue, whether or not it's, uh, causing a failure, um, but we can find that damage, uh, actually, um, scan the material of the debris, get a very accurate measurement of the size of it.

So is it, you know, is it pre-filter? Is it post-filter? Where is it coming from? Is it aluminum? Is it bearing material? Is it iron?
