I am interested in putting a small (3"x3"x2") assembly under X-ray, following a shock test, in order to evaluate failures of an internal ceramic piece. Unfortunately, this assembly utilizes quite a bit of potting material (epoxy) and as such, cannot easily be disassembled.
I'm considering reaching out to some local dentist practices to see if I can purchase X-ray time from them, however, I'm concerned that the material makeup of my assembly will not allow adequate penetration and will result in a poor image.
The general makeup of the assembly from the outside and moving inwards is...
- 0.125" thick aluminum outer casing
- 0.25" to 0.5" foam-like epoxy
- some small (but strong) magnets
- a ceramic "skeleton" structure (this is what I'm most interested in evaluating for failures)
Should note that the magnets are not necessarily in the line-of-sight of the ceramic, so 'penetration-ability' of those is a non-issue.
However, regarding the aluminum, with a HVL of 0.06" at 120 keV (source), I'm worried that I may not be able to sufficiently penetrate the outer shell and produce a good image.
MY QUESTIONS ARE:
- Penetration aside: Is it reasonable to suspect that I will be able to gather useful information and identify fractures in the ceramic?
- Google tells me that the typical energy capability of a dentistry x-ray is <200 keV. For someone with experience in the radiation field, do you expect this would be sufficient to penetrate my test article and produce a good image?
