Re: Trinitite Chunk Metal

 

Here is the Chunk, I guess it could be copper but as shiny as buffed copper? after 75+ years.

Steve,
That indeed is a good read, thank you. I have a piece of Red that has a chuck of what look like gold, shiny and not formed like the typical copper spheres. I will find and post a picture...has many many spheres on surface

Sure enough Scott, your pictures are clearer than mine. I need to work on that. The best sphere's in mine are solid black, but small, look like black shiny glass.

Re: Trinitite

 

Scott- pic of your red on and the big ball inclusion. I'll bet yours and mine were close neighbors once about 75 years ago. The theory is these were part of the fist structures to form during the explosion, a phenomenon they call "rope tricks", where a jet of plasma runs down the cable messenger melting the steel wire and all the copper conductors into Red Trinitite. If the camera is fast enough you can see the "legs: forming to the ground before the actual fireball.

PS on the thermal, it is OK to put a small fan nearby to help cool the body.?

Later we will work on a simple heatsink for the case.......Fins are good, not much heat to transfrer to air about 1 Watt

Could have done a longer scan but I was running out of time yesterday.

I acquired a cartoon of my car disposable parts goodies??late yesterday.

They consist of used brake pads ,fan belt??plus tensioner and the timing belt assembly.

The timing belt components are belt and multiple pulleys.Changing timing belt means replacing the the whole assembly .

After noting the xrf results,I was doing some investigative xrf of the other components??to explain my findings.

The metal??pulleys???also had iron and zinc.

Also checked out sometimes zinc is added to the oil used to lubricate certain timing belt systems.

Initially thought there was some contamination from nearby structures.

But this was ruled out

Car mechanics is very confusing too me especially when it comes to tensioners and lubricant oils on the timing belt.

Preliminary impression was the zinc and iron could have rubbed??off on the??old timing belt and got impregnated as silly as it may sound.

After I took a closer look at the timing belt ,the pieces of the puzzle started to fit.

I have some other??parts to xrf next time like the used???belt pulleys,brake pads??and tensioners which are very metallic indeed.

HI guys
Before doing this xrf .I knew little about timing belts and how they actually function.
I thought made of just plain rubber or something like that until my car timing belt almost snapped on the freeway weeks ago.
Replaced a new one together with the full timing belt kit.
Kept the old stuff for xrf.
Xrf was pretty short because? the peaks were appearing and therefore I decided no need for a longer scan.
Xrf with Am 241 show iron and zinc peaks.
On further reading noted that these belts are made of rubber reinforced with fibreglass,steel or neoprene.
Most likely the iron is in the cords and zinc as neoprene in the rubber
Pics are for a section of the timing belt exposing the cords and mca .

Re: Xrf timing belt

Dude

Yes I was expecting that ha ha

Could have done a longer scan but I was running out of time yesterday.

I acquired a cartoon of my car disposable parts goodies??late yesterday.

They consist of used brake pads ,fan belt??plus tensioner and the timing belt assembly.

The timing belt components are belt and multiple pulleys.Changing timing belt means replacing the the whole assembly .

After noting the xrf results,I was doing some investigative xrf of the other components??to explain my findings.

The metal??pulleys???also had iron and zinc.

Also checked out sometimes zinc is added to the oil used to lubricate certain timing belt systems.

Initially thought there was some contamination from nearby structures.

But this was ruled out

Car mechanics is very confusing too me especially when it comes to tensioners and lubricant oils on the timing belt.

Preliminary impression was the zinc and iron could have rubbed??off on the??old timing belt and got impregnated as silly as it may sound.

After I took a closer look at the timing belt ,the pieces of the puzzle started to fit.

I have some other??parts to xrf next time like the used???belt pulleys,brake pads??and tensioners which are very metallic indeed.

Here is longer scan of the timing belt

HI guys
Before doing this xrf .I knew little about timing belts and how they actually function.
I thought made of just plain rubber or something like that until my car timing belt almost snapped on the freeway weeks ago.
Replaced a new one together with the full timing belt kit.
Kept the old stuff for xrf.
Xrf was pretty short because? the peaks were appearing and therefore I decided no need for a longer scan.
Xrf with Am 241 show iron and zinc peaks.
On further reading noted that these belts are made of rubber reinforced with fibreglass,steel or neoprene.
Most likely the iron is in the cords and zinc as neoprene in the rubber

Re: Xrf timing belt

 

Nice catch on the metals in the rubber Taray. That's why we test everything!

And your direct exciter 59.5 leakage is almost not even detectable, just a little Compton? backscatter from it at the lower energy.
