I Rented a $35,000 X-RAY Machine to scan the metal used in Rotary Engines

Thank you!

Thanks for sharing!

Two Years Ago they were $75k. You should invest in a company making Smaller x-ray fluorescence machines

It's an old video and I'm sure it's been said but you are going to see trace material that is allowed. When you look at grades you need to look at the real certification that contains the range of alloys allowed in the specification. Any given manufacturer will hold to a different standard with where they hold to things. Each batch will be different and in any important item material certifications that need to travel with the item.

Metals also require heat treatment and it can make a bigger difference than your alloy.

You need clean steel for good testing. The way you are talking about elements is not exactly how they work. I like your style though.

So what I'm also very curious about is how those surfaces are made. I'm guessing it's sputtered, but that means that the sputter parameters matter quite a lot for the surface structure and thus hardness. Might be nice to look into but we'd need things like electron/afm microscopes. Maybe applied science can help

Brilliant, keep up the good work

Fantastic analysis. Still hoping for a hydrogen-powered rotary one day. Awesome channel, Rob!

Wow this video is awesome!

What if the apex seal was gold?

Another very important part of wear resistance and strength is the heat treatment the metal has been subjected to.
4140 annealed ie. soft is much, much, weaker than 4140 heat treated to iys maximum strength.

A true Scientific approach to a normally opinion based topic. Love to see it. Give this man a PhD in Rotary Sciences.

Make parts keep forward El Boricua de California 👍🇵🇷✌️

XRF is X-Ray Florescence. Essentially it works by exciting electrons in each element to cause them to fluoresce emitting light. Each element emits light with a unique spectral signature, like a fingerprint. The various spectral signatures from the sample are detected, analyzed, and compared to a database preloaded on the unit. It's the same way we can know the composition of distant bodies in space. Such a cool tool. I can't wait until they are more affordable. I want to go pick one up at my local Harbor Freight.

Basicly u can't measure carbon with device like that it is science. Unfortunately it is one of the most important particle in Iron based alloys. Also phase composition is unknown. But for start of material science is good solid measurement.

What a guy

i used to hate rob back in the day when he used to make the diablo vids, now he is one of my favs ...

nikasill, coat it with nikasill , its the bees knees
