Résumé

In the manufacture of wood objects, for binding and strengthening were used nails, cramps and other metallic elements, which in the archaeological site suffered degradation and deterioration processes, specific to metal-wood interface. The chemical and physical-structural characteristics of the products resulted from metal-old wood interactions can set up a database that can be used in authentication. For the study were taken wood samples from the Roman and Byzantine era, from Dobrogea and Moldova areas, resulted from the archaeological excavations, after year 2000, which presented in their structure metallic elements. The samples were analyzed with scanning electron microscope coupled with energy dispersion X-ray (SEM-EDX).
