  • Interesting fact: From bridges to rebar, rust is everywhere. According to a recent study, the annual cost of metallic corrosion in the U.S. is approximately $300 billion. The report, by Battelle, Columbus, Ohio, and the Specialty Steel Industry of North America, Washington, D.C., estimated that about one-third of that cost could be avoided through broader application of corrosion-resistant material and "best anti-corrosive practice" from design through maintenance.
    • Rust (Bot) A minute mold or fungus forming reddish or rusty spots on the leaves and stems of cereal and other grasses (Trichobasis Rubigo-vera), now usually believed to be a form or condition of the corn mildew (Puccinia graminis). As rust, it has solitary reddish spores; as corn mildew, the spores are double and blackish.

  • Interesting fact: Iron weighs more after it rusts.
    • n rust The red or orange-yellow coating which is formed on the surface of iron when exposed to air and moisture; red oxid of iron; in an extended sense, any metallic oxid forming a coat on the metal. Oil-paint, varnish. plumbago, a film of caoutchouc, or a coating of tin may be employed, according to circumstances, to prevent the rusting of iron utensils.
    • n rust In metal-working, a composition of iron-filings and sal ammoniac, with sometimes a little sulphur, moistened with water and used for filling fast joints. Oxidation rapidly sets in, and the composition, after a time, becomes very hard, and takes thorough hold of the surfaces between which it is placed. A joint formed in this way is called a rust-joint.
    • n rust In botany, a fungous growth on plants which resembles rust on metal; plant-disease caused by fungi of the class Uredineæ (which see, for special characterization): same as brand, 6. See Fungi, mildew, Puccinia, and Trichobasis; also black rust and red rust, below.
    • n rust Any foul extraneous matter; a corrosive, injurious, or disfiguring accretion.

    • rust An obsolete variant of roost.
    • n rust Rust formed on iron by exposure to air and water often approaches pretty closely in composition the mineral limonite, a ferric oxyhydroxid (Fe4O3(HO)6). It also frequently contains some ferrous or ferrosoferric oxid and hydroxid, and is more or less perceptibly magnetic.

With them thy sons might well have striven,
And their blood-rusted fetters riven;
But why, in Heaven's name, should we
Shoot men aspiring to be free?

However, this has not been demonstrated by observations [Rust et al., 2008]. A fourth possibility, recently suggested by Lockwood et al. [2009a, b], is that flow speed variations in the solar wind above 2.5R⊙ could lead to an increase in the unsigned radial flux at increasing distance from the Sun.
