Microscope section measurement of coated Film thickness
Microscope cross-section measurement method, as shown in Figure 6-1, is also equipped with a microscope with micrometer eyepieces to measure the cross-section of the coating pattern, and measure more than two fields of view, each market is measured at least at equal intervals 5 points, with the average or minimum value as the thickness of the coating.
In tempering and grinding, plastics or numbers can be used to inlay events, so as to ensure that the film surface is perpendicular to the coating surface, and prevent burrs or water chestnut rounding, and the interface between the coating and the substrate material can be clearly exposed by using corrosive agents , convenient and accurate measurement.
Yes, the magnification of 20 times can be used for the month map coating, and the magnification of 200~500 times can be used for observation and measurement of the brush map coating.
