Metallographic replicas allow nondestructive analysis of the surfaces of materials and components. This method is used to monitor the condition of critical structures without damaging them. We offer high-precision replication services for preventive maintenance and metallurgical research.
Micrographic examinations are generally destructive examinations because they are performed after dissecting the artifact or material to be tested, an operation that is not possible when the part has been manufactured or even put in place.

There are cases, however, where it is necessary to know the microstructure of the material and its evolution over time, even when the artifact is placed in place and in operation, in order to assess its state of possible degradation.
And it is precisely in these cases that metallographic replicas come into play.

The execution of metallographic replicas is carried out in the following way: after grinding the surface of the artifact using abrasive papers, it is polished to a high gloss using diamond pastes or electrolytically. The polished surface is then attacked with chemical or electrolytic attacks, and later a film, which may consist of various types of polymeric materials, is laid on it. The microstructure of the material remains imprinted on that film. The film is then removed and placed on a slide, which can be observed in situ using a portable light microscope or later in the laboratory.
