Metallography and Plastography

Analysis in detail

In metallography materials are tested with respect to their structural properties. One of the best image analysis methods supports our metallographers in the daily analysis of very different materials.

In addition to the actual metallography we also do plastography, which deals with non-metallic materials. Here we test primarily composite materials, such as e.g. carbon fiber reinforced plastics (CFRP).

In special cases it is possible by means of ambulant metallography to test components on site or when installed non-destructively. In this connection replicas are taken which are then microscopically evaluated in the laboratory. This method is used for example in the inspection of creep rupture damages within the scope of plant reviews.

Thus we also offer a comprehensive solution for our clients in the area of metallography, plastography and mobile analysis:
