Non-destructive failure analysis

For industrial samples, quality control or failure analysis is vital to future product improvements. This polypropylene coated metal sample failed quality control tests due to poor coating adhesions. A section of the coating was removed and the entire sample was inserted in the MiniFlex for testing.

The answer was rust! A thick layer of corrosion was forming between the metal substrate and the polypropylene.

Non-destructive failure analysis is one of the benefits of X-ray diffraction.


New sixth generation MiniFlex X-ray diffractometer (XRD) is a multipurpose analytical instrument that can determine: phase identification and quantification, percent (%) crystallinity, crystallite size and strain, lattice parameter refinement, Rietveld refinement, and molecular structure. It is widely used in research, especially in material science and chemistry, as well as in industry for research and quality control. It is the newest addition to MiniFlex series of benchtop X-ray diffraction analyzers from Rigaku, which began with the introduction of the original MiniFlex system decades ago. Read more...
