Oxidation numbers
... In fact, oxidation never takes place on its own - nor does reduction. When one substance is oxidised in a reaction, another one is reduced. A Redox reaction is one in which both reduction and oxidation take place. To work out which element is oxidised and which is reduced in a reaction, we go throug ...

... Rules for assigning oxidation numbers: 1. Elements in their most abundant naturally occurring form are assigned an oxidation number of zero. e.g. Na, Fe, Cl2, O2 2. The sum of the oxidation numbers for a compound or formula unit is zero. 3. For a polyatomic ion, the oxidation numbers of the constit ...

Superalloy
A superalloy, or high-performance alloy, is an alloy that exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability and resistance to corrosion or oxidation. The crystal structure is typically face-centered cubic austenitic. Examples of such alloys are Hastelloy, Inconel, Waspaloy, Rene alloys, Haynes alloys, Incoloy, MP98T, TMS alloys, and CMSX single crystal alloys.Superalloy development has relied heavily on both chemical and process innovations. Superalloys develop high temperature strength through solid solution strengthening. An important strengthening mechanism is precipitation strengthening which forms secondary phase precipitates such as gamma prime and carbides. Oxidation or corrosion resistance is provided by elements such as aluminium and chromium.The primary application for such alloys is in turbine engines, both aerospace and marine.
