Metallographic Microscopy
Expert Metallographic Analysis
How it Works
Metallographic microscopes differ from traditional microscopes in the way they illuminate the sample. The light is passed through the aperture and onto a polished sample surface. The light is usually modified using polarizers, apertures, lightfields, darkfields, and other lenses and filters. These different lighting effects allow for different types of surface analyses.
Applications
A common use of metallographic microscopes is grain structure and grain size analysis in metals. A corrosive etchant preferentially attacks grain boundaries on a polished metal surface, making them more defined. Another common use is coating thickness measurement of paints and multi-layered materials. Metallographic microscopy also plays a significant role in our failure analysis investigations as can be seen in the slideshow above.
