X-Ray Fluorescence XRF Plating Measurement
XRF instruments use X-ray fluorescence technology to determine the thickness and composition of plating deposits with exceptional accuracy. Measurement is performed by exposing a precisely defined area of the test specimen to x-ray energy. This causes X-ray emission (fluorescence) from both coating and substrate, which is detected with a high precision energy-dispersive detector. Energy resolution, detection efficiency, and robustness are three factors relative to detectors.
Where layers of pure metals or alloys are used to enhance product features, it is important to precisely determine both coating thickness, and the elements in the sample.
