Abstract:

The paper presents the mechanism of obtaining polychrome layers by microcrystalline phosphatation of iron objects. These ornamental layers must be aesthetic and must offer protection against corrosion induced by various climatic conditions. Chemical and physical-structural, analyses were carried out by OM and SEM-EDX, in order to verify the obtaining processes. The procedure described by the patent can be applied to new objects but also to ancient artifacts, that must be chromatically reintegrated, after restoration.
