non destructive analysis of interfacial decohesion in layered thin coatings

Dear NDT coolleagues

I am looking for researchers that have been using NDT techniques to study adherence problems in thin films and coatings (for protective and decorative applications). Namely, the micro defects and decohesion at interfaces between a coating and substrate (or within one interface of multilayered coatings).

I will appreciate very much information on the techniques used, papers published and experience.

Thanks

Wishes of an Happy New Year.

Re: non destructive analysis of interfacial decohesion in layered thin coatings
We have applied High Frequency UT to measure the adherance of thin film materials to a variety of substrates. Our UltraWin software has a semi-automated Bond Analysis function to aid in the rapid interpretation (e.g. Go-No Go type) of C-Scan imaging data from just such material bonding issues.

I will also forward you (to your e-mail) a copy of an applications study detailing this type of work and capabilities - hope it helps you.

Product Spotlight

SITEX CPSERIES

Teledyne ICM’s CPSERIES has been designed with a view to revolutionizing the handling and perfor
...
mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
