AB  - The degree of preservation of iron artifacts depends on the type of underground environment and the type of corrosion products formed on their surface. This paper analyses the conditions of an archaeological find made of iron and originating from the Roman period and belonging to the collections of the Museum of Science and Technology in Belgrade. The radiographic method has been used to determine the quantity of non-corroded metal as well as to determine the presence of cracks and other defects in the artefact. The composition of the corrosion products has been analysed by the X-ray diffraction method (XRD). In addition to iron corrosion products (goethite α-FeO(OH) and magnetite Fe3O4), the presence of a significant quantity of akaganeite β-Fe8O8(OH)8Cl1.35, has been noticed on the artifact. The content of chloride, sulphate and other ions in the corrosion products has been determined by ion chromatography (IC). The analyses have pointed to the necessity of having artifacts treated in adequate solutions immediately after their excavation in order to eliminate chloride and sulphate anions. The aim of this paper is to determine the type of corrosion products and their influence on the corrosion behaviour ofr an archaeological artefact.
AB  - Koroziona postojanost eksponata od gvožđa zavisi od tipa podzemne sredine i vrste korozionih produkata koji se formiraju na njegovoj površini. Ovaj rad analizira stanje arheološkog predmeta koji potiče iz rimskog perioda i koji pripada kolekciji Muzeja za nauku i tehniku u Beogradu. Radiografska metoda je korišćena za određivanje količine nekorodiralog metala, kao i prisustva prslina i drugih defekata u eksponatu. Sastav korozionih produkata je analiziran difrakcijom X-zraka (XRD). Pored korozionih produkata gvožđa (getita α-FeO(OH)I magnetita Fe3O4), uočena je značajna količina akagenita β-Fe8O8(OH)8Cl1.35 u sloju korozionih produkata. Metodom jonske hromatografije (IC) je određen sadržaj hloridnih, sulfatnih i drugih jona u korozionim produktima. Pomenute analize su ukazale na neophodnost tretmana arheološkog predmeta u odgovarajućem rastvoru za desalinaciju, neposredno posle iskopavanja, u cilju uklanjanja hloridnih i sulfatnih anjona. Cilj ovog rada je određivanje tipa korozionih produkata i njihovog uticaja na koroziono ponašanje arheološkog predmeta.

AB  - This paper analyzes the state of the French Cannon 75/27 model 1911.
Déport made of steel. The amount of non-corroded materials, the presence
of cracks and other defects in the cannon were determined by the
radiographic method. The composition of corrosion products were
analyzed using diffraction of X-rays (XRD method). In addition to goethite
α-FeO(OH), lepidocrocite γ-FeO(OH) and magnetite Fe3O4, the presence
of akaganeite was observed in the corrosion products, β-Fe8O8(OH)8Cl1.35
which indicates the accelerated corrosion of the base metal. With the ion
chromatography method, the content of chloride, sulphate and other ions
in corrosion products were examined. On the basis of conducted
experiments, it can be concluded that it is necessary to treat the cannon in
appropriate solutions, as quickly as possible, to remove chloride and
sulphate ions.

AB  - A degree of preservation of iron artefacts depends on the type of underground environment and the type of corrosion products formed on their surface. This paper analyses the conditions of an archaeological artefact made of iron, which was found to originate from the Roman period. The iron corrosion products, goethite, lepidocrocite and magnetite (determined by the X-ray diffraction method) have been noticed in the corrosion products of the artefact. The ion chromatography analysis has revealed chloride and sulphate anions, pointing to the necessity of having artefacts treated in adequate solutions immediately after their excavation. It has been found that the EDTA solution is very efficient in the process of desalination of the artefact. The aim of this study was to determine the influence of the corrosion product types and the effects of applying the EDTA solution, otherwise not commonly used for desalination of iron objects. This method was applied here due to the complex structures of the found archaeological artefacts and the presence of copper alloys besides iron. The aim of this paper is to determine the type of influence corrosion products have on an artefact and to determine the effect of desalination treatment.
