Abstract: (2535 Views)
The artifact studied in this paper is a bimetallic sword made of bronze handle and an iron blade, which was excavated from the Tol ancient cemetery, located in Talash city, Gilan province, in 2001 by Mohammad Reza Khaltabari. This research aims to study the technology and pathology of the mentioned object by conducting comparative and archeological studies using the library method, conducting technological studies using the laboratory methods of radiography, metallography, and microstructural observations using a scanning electron microscope (SEM-EDS). The phase analysis of corrosion products was done by X-ray diffraction (XRD), as well as knowing the manufacturing method and identifying the types of damage and corrosion. The result shows that this work belongs to the Iron Age. Also, the tests performed on the two parts of the handle and the blade showed that the material of the iron blade is iron-carbon alloy. The amount of carbon in different parts of the body of blade is not the same and the handle is made of bronze alloy with casting and hammering techniques. It also has a galvanic corrosion effect.
