A previous study employed the weight loss approach of the treated coupons after exposure to 85% relative humidity in a humidity chamber to assess the effects of Oak Galls Extract (OGE) as a green corrosion inhibitor of cast iron (iron artifacts) in the atmospheric environment. The morphology of an adsorbed inhibitor on the surface was also studied...

This research aims to study two gilded hollow bronze statues from pharaonic Egypt excavated in a karnak temple. The two objects had an unusual casting core and one of them was gelded on the ground. Various parts and layers, including the casting core, gold layer, gilding ground, corrosion products, and metallic structures, were characterized via sc...

The current study aims to characterize a heavily corroded bronze statue from Pharaonic Egypt, in terms of the morphology and mechanism of corrosion. The characterization was carried out by a combination of methods, including the scanning electron microscope equipped with energy dispersive X‐ray spectroscopy (SEM–EDS), USB digital microscope, X‐ray...

The work aims to study the manufacturing technique, microstructure features, and morphology and mechanism corrosion of a hammered copper basin belonging to one of the early metallurgy ages in ancient Egypt ( the old kingdom). The examination and analysis were carried out by USB microscope, polarized light microscope, scanning electron microscope eq...

The article focused on the multi analytical characterization of unique copper model tools date back to the dynasty Xth, 1st intermediate period (c.2134-2050). The studied set consists of twenty-five objects that were excavated in the tomb of KHENNU AND APA-EM-SA-F (289) in the south of Memphis, Saqqara. Different microscopes were used to examine th...

The aim of this work is to investigate the effectiveness of oak galls extract (OGE) as a green corrosion inhibitor from natural resources to prevent the corrosion of archaeological iron artifacts in atmospheric environments. The inhibition efficiency has been evaluated by measuring the weight loss of the treated coupons after exposure to 85% RH in...

The study of chemical composition and microstructural features of ancient coins provide researchers with invaluable and priceless information which can contribute to forgery detection. This study was conducted on nine copper and bronze coins preserved in a private collection in Egypt. Elemental analysis was performed to determine the major and trac...

Abstract In this paper, a sword is investigated from a collection of archaeological iron swords displayed in the Egyptian Museum from the civilization centered on Ballana and Qustul in Egyptian Nubia (380–600 A.D.). A range of metallographic analytical techniques have been used to characterize the sword’s metallic structure and its rust crust. The...

The main objective of this subject was a comparative study of inhibition and protective properties among the best and common compounds used to Copper artefacts protect in atmospheric environment. Compounds were five of the best corrosion inhibitors: L-Methionine (Met.), L-Cystine (Cys.), Benzotriazole (BTA), 3-amino-1, 2, 4-triazole (ATA) and Sodiu...
