AB  - A spearhead of archaeological and cultural significance has been found and analysed in
Serbia. In the corrosion products of the artefact, the dominant phases were goethite (α-
FeO(OH)) and magnetite (Fe3O4) whose presence explains a good preservation of the base
metal, iron, over the centuries and the artefact stability after excavation. Besides goethite and
magnetite, the corrosion products were identified to contain, to a lesser extent, less stable
lepidocrocite (γ-FeO(OH)) and the phases that come from the rocks and soil from the
surrounding environment (plagioclase). The phases containing chloride ions were not detected
in the corrosion products (akaganéite, β-Fe8O8(OH)8Cl1.35), which indirectly indicates that the
content of chloride ions was not significant in the underground exploitation conditions. The
lack of chloride ions also contributed to the corrosion stability of the artefact during the period
after excavation.

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.

AB  - This paper analyzed the conditions for the occurrence of cor-
rosion processes on historically important weapons and military 
equipment made of steel during the period in outdoor environment. 
A considerable attention has been given to the characteristics of 
the most important corrosion products formed on the steel surface. 
The formation of akaganite,  -FeOOH is a sign of active corrosion 
under a layer of corrosion products. The conditions that cause the 
formation and regeneration of hydrochloric and sulphuric acid du-
ring the exposure to the elements were analyzed. The most often 
applied methods of diagnostics and procedures of removing active 
corrosion anions (desalination) were described as well. The NaOH 
solution of certain pH values still has the most important applica-
tion for the desalination process. The procedures for cleaning the 
surface before the application of protective coatings and the appli-
cation of chemicals that transform rust into stable compounds we-
re discussed. As protective coatings, different types of organic co-
atings plated on well-prepared steel surfaces were used and so-
metimes special types of waxes as well. This paper presents the 
results of the tests of corrosion products taken from the exhibits of 
weapons and military equipment from the Military Museum in Bel-
grade.
