The conservation and restoration of iron and steel objects is an activity dedicated to the preservation and protection of objects of historical and personal value made from iron or steel. When applied to cultural heritage this activity is generally undertaken by a conservator-restorer. Historically, objects made from iron or steel were created ...
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron (III) oxides (Fe 2 O 3 ·nH 2 O) and iron (III) oxide-hydroxide (FeO (OH), Fe (OH) 3), and is typically associated with the corrosion of refined iron.
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.
Tilted Arc was a controversial public art installation by Richard Serra, displayed in Foley Federal Plaza in Manhattan from 1981 to 1989. It consisted of a 120-foot-long (37 m), 12-foot-high (3.7 m) solid, unfinished plate of rust-covered COR-TEN steel. Advocates characterized it as an important work by a well-known artist that transformed the ...
The iron pillar of Delhi is a structure 7.21 metres (23 feet 8 inches) high with a 41-centimetre (16 in) diameter that was constructed by Chandragupta II (reigned c. 375–415 CE), and now stands in the Qutub complex at Mehrauli in Delhi, India. [1][2] It's mostly known for its unique rust-resistant composition that was unprecedent for its time ...
Oxide jacking. The expansive force of rusting, which may be called oxide jacking or rust burst, is a phenomenon that can cause damage to structures made of stone, masonry, concrete or ceramics, and reinforced with metal components. A definition is "the displacement of building elements due to the expansion of iron and steel products as the ...
Galvanization. Galvanized surface with visible spangle. Galvanization or galvanizing (also spelled galvanisation or galvanising) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten ...
Rustproofing is the prevention or delay of rusting of iron and steel objects, or the permanent protection against corrosion. Typically, the protection is achieved by a process of surface finishing or treatment. Depending on mechanical wear or environmental conditions, the degradation may not be stopped completely, unless the process is ...
