Ultrasonic Detection of Adhesive Bonds

The product in question is typified by a torus of rubber bonded between two steel cylinders. Has there been any success in detecting disbonds in this type of construct?

I typed an earlyer message but, got cut off by the demand on the server on my end. This may be a duplicate.
If used properly and the limitations of ultrasonic inspection are observed. You can either image the bond using C-scan or automate using A-scan the inspection of sealers used in automotive applications and some of the rubber components.
I worked on the Henry Ford Technology Award team for 2000 At vehicle ops for North America.
The only company ready to do this is IRT Scan Master A sponser of this Fourm.
They have the only patented high out put transducer that is necessary to perform the inspection of the material in question.
If you need assistance on a full or part time basis I am available to reproduce our qualification method for this inspection.

Dear John,

We have made some simple trials using Quasar Resonant Inspection (QRI) on some "Vibration Dampers", which in effect are two plates of steel with a rubber block bonded between them, or rather similar to what you describe.

These initial tests suggested that the technology could detect disbonds as well as some other problems in the manufacture.
However, the customer then had a severe reduction in budget, so was unable to pursue the technology further.
These tests were made here in the United Kingdom, but Quasar International is based in Albuquerque, NM.

I suggest you contact the office over there on (505) 247 9660.

Regards,

Godfrey Hands

Re: Ultrasonic Detection of Adhesive Bonds
We have successfully done work with very thick metal to rubber composites using Acousto-Ultrasound. Try talking to Physical Acoustics princeton new jersey its their technology we use.

s. This projector incorporates design and safety features that make it flexible, compact and lightweight. The Projector is lighter than most of its competitors. It incorporates an improved source channel, based on a new helicoidal design, which makes maintenance easier. The helicoidal design also allows smoother movement of the source assembly inside the device, making it easier for the operator and improving safety. The Projector also has a unique safety feature not found in competitive products. The source assembly locking mechanism is triggered by the source holder capsule at the front of the source assembly, thereby always assuring the operator that the source has returned to the safe position. The Exertus Dual 120 is ISO3999:2004 compliant.
