Analysis of metal coating types and
thickness
The portable, hand-held A2 Technologies Exoscan allows even large complex parts to be directly measured in any orientation eliminating the need for sample disassembling or destruction
A2 Technologies says its hand-held FTIR system, Exoscan, has the performance capability to provide accurate measurement of anodization thickness and type on large parts, without the need to dissemble or otherwise modify the part for testing In a new application note entitled 'Metal coatings analysis using the Exoscan hand held FTIR', the system demonstrates why it is ideal for non-destructive analysis of samples that are too large to bring to the laboratory or too valuable to require a small portion to be removed for analysis

Results demonstrate that by using the high performance external reflectance sampling interface, Exoscan can identify and quantify even the thinnest anodized coatings as well as paint and primer coatings on metal surfaces.
Since a variety of coatings can be used to protect a metal surface from corrosion or to impart specific properties, it is important to ensure that the selected coating has been applied via the correct process and at the desired thickness.
Infrared spectroscopy has been shown to be capable of carrying out this coating verification, but only using laboratory spectrometers and only for samples that were the proper shape and size to be accommodated by the spectrometer.
Exoscan enables the coatings on any size surface to be analysed directly where the metal part is located, for example on the manufacturing floor or in a maintenance shop. Request a free brochure from A2 Technologies ...
