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  - U ovom radu analizirano je stanje francuskog topa 75/27 model 1911 Déport izrađenog od čelika. Za određivanje količine nekorodiralog materijala, prisustva prslina i drugih defekata u eksponatu korišćena je radiografska metoda. Sastav korozionih produkata je analiziran metodom difrakcije rendgenskih zraka (XRD). Pored getita, α-FeO(OH), lepidokrokita, γ-FeO(OH) i magnetita, Fe3O4, na eksponatima je uočeno prisustvo akaganita koje ukazuje na aktivnu koroziju osnovnog metala. Metodom jonske hromatografije je određen sadržaj hloridnih i drugih anjona u korozionim produktima. Na osnovu izvedenih eksperimenata nameće se zaključak o neophodnosti tretmana topa u odgovarajućim rastvorima što je moguće pre u cilju uklanjanja hloridnih i drugih koroziono aktivnih jona.

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 analyzed 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 behavior of an archaeological artefact.
