Derveni krater, bronze, 350 BC, height: 90.5 cm (35 1 ⁄ 2 in.), Inv. B1, Archaeological Museum of Thessaloniki, after cleaning and conservation. Conservation and restoration of metals is the activity devoted to the protection and preservation of historical (religious, artistic, technical and ethnographic) and archaeological objects made partly or entirely of metal.
Analysis and observation of collections objects when considering treatment and restoration occurs at all steps of the conservation process. Metal objects such as iron and steel share properties such as strength, conduction of heat and electricity, structure and more. It is important to understand the properties before conducting treatment.
Silver is known in the chemistry world as a noble metal, which means it is resistant to corrosion, but not completely immune. Whether silver plating or pure silver, the composite of the metal will tarnish when exposed to air and sulfur. Tarnish is a chemical reaction on the surface of metal (copper, brass, silver, etc.) and causes a layer of ...

Conservation-restoration work on historic firearms is a series of procedures designed to stabilize, repair or restore parts, and stop deterioration. [1] Stabilizing a firearm means establishing the ideal environment conditions, removing corrosion, replacing missing components, and repairing broken parts.
It is often used to improve mechanical properties or increase corrosion resistance, repair worn out parts, [5] [6] and fabricate metal matrix composites. [7] Surface material may be laser cladded directly onto a highly stressed component, i.e. to make a self-lubricating surface. However, such a modification requires further industrialization of ...
