the copper skin and the wrought iron support structure. The corrosion was so extensive that there was a concern the statue might collapse. As a result renovation works had to be done in 1986 where the wrought iron framework was replaced by stainless steel which did not corrode in the presence of copper‚ coated in a layer of PTFE insulation. Problem analysis: Galvanic corrosion is an electrochemical process in which one metal corrodes preferentially to another when both metals are in electrical contact

Introduction and Hypothesis: Rust is a reddish or yellowish-brown flaky coating of iron oxide that is formed on iron or steel by oxidation‚ especially in the presence of moisture. The rusting process is electrochemical‚ meaning it forms from a chemical reaction which takes place in a solution where there is an electron transfer between the electrode and the electrolyte or species in solution. In the case of rusting‚ the transfer of electrons from iron to oxygen begins the electrochemical process

properties by selecting appropriate temperature and mechanical working. Hot working range and effects 1. Near 370C metal strength decreases and plasticity increases until at lowest temperature where the lowest melting constituent of steel starts to melt. The strength decreases and looses plasticity and tind to crumble under applied stress instead of flow. 2. Selection of temperature depends on a) Chemistry. b) Melting point of the lowest constituent. 3. Finishing temperatures

SPHERODITE AND (g) TEMPERED MARTENSITE. (a)ALLOY • Alloy steel is often subdivided into two groups: high alloy steels and low alloy steels. The difference between the two is defined somewhat arbitrarily. However‚ most agree that any steel that is alloyed with more than eight percent of its weight being other elements beside iron and carbon‚ is high alloy steel. Low alloy steels are slightly more common. The physical properties of these steels are modified by the other elements‚ to give them greater

convert entirely to rust and disintegrate. Surface rust is flaky and friable‚ and provides no protection to the underlying iron‚ unlike the formation of patina on copper surfaces. Rusting is the common term for corrosion of iron and its alloys‚ such as steel. Many other metals undergo equivalent corrosion‚ but the resulting oxides are not commonly called rust. Other forms of rust exist‚ like the result of reactions between iron and chloride in an environment deprived of oxygen – rebar used in underwater
