Analysis OF Nanosilica AND Paraloied Coatings For Corrosion Protection Of Historical Steel Alloy

The era between 550-1500 BC (about one thousand years ago) was called Iron age of Iran since in this era the use of iron changed the economic and social condition because it is moreresistant than Copper and Bronze, .North and center of Iran are the places which have the most historical metals speciallyweapons. One of the universal problems is the corrosion that is the decay and loss of material due to chemical attack especially on historical steel alloys. The aim of the presentresearch is to study corrosion resistance and protective ability of hybrid nanocomposite based on nano silica-paraloied pretreatmentson historical steel alloys. These historical steel alloys are chosen from Zivieh, a historical area which is located on a hill in the east of Saqqez in Kurdistan
