Green Corrosion Inhibitor for Protection of Conserved Some Archaeological Iron Spears Heads from Military Museum, Al-Qala, Egypt

Abstract

AbstractArchaeological iron artifacts are often covered with a crust, containing organic fibers, mineral particles, dirt, etc. Before conservation, this crust must be carefully removed. With traditional mechanical and chemical methods, there is an obvious risk of over-cleaning. These methods also increase the risk of the oxidized or primary corrosion layer breaking away which will lead to loss of information about the form of the object and other important surface details. The same archaeological iron spears from Military Museum, Al-Qala, Egypt were selected for the study. The aim of this case study is concerned with preserving and controlling the corrosion of steel spears heads. Due to the restriction of the archeological parts preservation and corrosion control are achieved by environmentally friendly chemicals. This inhibitor is of attentiveness since there has been a growth in ecological consciousness and a variation in guidelines that control the toxicity of systematic corrosion inhibitors. So, natural products are becoming the main source of environmentally friendly corrosion inhibitors. Furthermost their extracts comprise the required features of the traditional corrosion inhibitors such as oxygen, carbon, nitrogen, and sulfur. These elements are contributed to the adsorption process on the metal surfaces and arrangement a protective layer, which shields the metal surface against environmental corrosion. Progress of green chemical knowledge compromises a new artificial approach for ionic liquids. These compounds are well-thought-out as new safe corrosion inhibitors which act in different corrosive conditions. Finally, exploiting the successfully obtained results, we used this inhibitor to protect the selected objects.
