Physical and chemical structure of the archeologic iron samples
Methods x-ray diffractometry, metallography, atomic force microscopy, x-ray photoelectron spectroscopy investigate structure and structure of samples of archeologic iron from site of ancient settlement Idnakar IХ-ХIII of centuries (the Udmurt Republic). It is established, that the sample of archeologic iron has the layered structure formed repeated welding of layers with the various maintenance of carbon. The material of the sample is non-uniform on structure and physicomechanical properties. It is established, that metal was exposed to partial training. Large nonmetallic inclusions in the sample are connected, on visible, with technology of the iron reception. A surface of the sample concentrated the chlorine-containing connections having high corrosion activity. Presence of the developed system of times, cracks and nonmetallic inclusions both on a surface, and in volume of the sample does application of traditional methods of preservation of archeologic products ineffective. For metal products with similar structure more effective is the vacuum-plasma method of preservation developed by us.
