In this method, a part of the sample is separated and embedded in a synthetic resin. By defined grinding and polishing steps, a cross-section of the portion to be analyzed is prepared and viewed at appropriate magnification with an optical microscope. In addition to pure micrography, thickness measurement of individual layers and assessment of edge coverage of coatings is also possible. Suitable etching processes can also be used to enable a microstructure analysis of metals and alloys. Direct assessment and three-dimensional topographic images of small sample parts with up to 6000x magnification are also feasible.
This test is part of the following manufacturer and requirement standards:
