Metal is a living material\u2026 With the exception of pure gold in its natural state, all metals are derived from the transformation of mineral ores. Once altered, from ore into semi-finished products such as ingots, billets, blooms or slabs, and then into objects or structural elements, metals will continually seek, throughout their service life, to return to their natural state as mineral ore (hydroxides, oxides, sulphides, carbonates, etc.). A leopard cannot change its spots!<\/p>\n\n\n\n
This process of \u2018returning to its natural\nstate\u2019, from metal to \u2018mineral ore\u2019, is called corrosion. From an etymological\nperspective, the term corrosion comes from the ancient Latin verb corrodere,<\/em> which means the \u2018action of\ngnawing\u2019. According to current norms, especially standard ISO 8044, corrosion is\ndefined as the result of the physico-chemical interaction between a metal and\nits environment leading to modifications in the proprieties of the metal that\ncan result in deterioration of its function, the surrounding environment or the\ntechnical system to which it belongs.<\/p>\n\n\n\n The term corrosion includes a myriad of\ndifferent mechanisms: uniform corrosion, corrosion by differential aeration or\nby galvanic cell, pitting corrosion, corrosion under deposits, crevice corrosion,\nerosion corrosion, cavitation corrosion, filiform corrosion, localised corrosion,\netc. <\/p>\n\n\n\n Identifying and diagnosing corrosion in a system involving of one or\nmore metals, and one or more environments, requires studying the nature of the metal(s)\npresent and the environment(s) encountered. <\/p>\n\n\n\n As both a consulting firm and a\nconservation-restoration laboratory, A-CORROS is here to help you identify and\ndiagnose any corrosion pathologies, and understand the causal\nmechanisms in order to determine the best recommendations to\nsuccessfully combat corrosion. <\/p>\n","protected":false},"excerpt":{"rendered":" Metal is a living material\u2026 With the exception of pure gold in its natural state, all metals are derived from the transformation of mineral ores.
