  1. Rust

    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 (Fe2O3·nH2O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3), and is typically associated with the corrosion of refined iron. Given sufficient time, any iron mass, in the presence of water and oxygen, could eventually convert entirely to rust. Surface rust is commonly flaky and friable, and provides no passivational protection to the underlying iron, unlike the formation of patina on copper surfaces. Rusting is the common term for corrosion of elemental iron and its alloys such as steel. Many other metals undergo similar corrosion, but the resulting oxides are not commonly called "rust".Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Other forms of rust include the result of reactions between iron and chloride in an environment deprived of oxygen. Rebar used in underwater concrete pillars, which generates green rust, is an example. Although rusting is generally a negative aspect of iron, a particular form of rusting, known as stable rust, causes the object to have a thin coating of rust over the top. If kept in low relative humidity, it makes the "stable" layer protective to the iron below, but not to the extent of other oxides such as aluminium oxide on aluminium.


  1. rust

    Rust is a reddish or orange-brown flaky coating of iron oxide that is formed on iron or steel by oxidation, especially in the presence of moisture. It is the result of a chemical reaction called corrosion, which occurs when iron comes into prolonged contact with water and oxygen. Rust can lead to the degradation of the metal, reducing its strength and functionality. It is typically undesirable and measures are often taken to prevent its formation or remove it.

    the reddish yellow coating formed on iron when exposed to moist air, consisting of ferric oxide or hydroxide; hence, by extension, any metallic film of corrosion

  3. Rustnoun

  4. Rustnoun

  5. Rustnoun

  12. Etymology: [AS. rustian.]


  1. Rust

    Rust is composed of iron oxides. In colloquial usage, the term is applied to red oxides, formed by the reaction of iron and oxygen in the presence of water or air moisture. Other forms of rust exist, like the result of reactions between iron and chloride in an environment deprived of oxygen – rebar used in underwater concrete pillars is an example – which generates green rust. Several forms of rust are distinguishable visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron oxides Fe2O3·nH2O and iron oxide-hydroxide FeO·Fe(OH)3. Given sufficient time, oxygen, and water, any iron mass will eventually 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.

Examples of RUST in a Sentence

  1. Craig Holt:

    Given what's going on in Central America with leaf rust and the drought in Brazil, you want to look at other options.

  2. Donald Duncan:

    In 1997 we were the fastest growing manufacturing metro area in the country and four years later it collapsed, what you can see on the ground today is 3,000 job openings. China's emergence as the world's low-cost producer and export superpower following its World Trade Organization entry in 2001 dealt a heavy blow to traditional industrial communities such as Hickory. Economists David Autor, David Dorn and Gordon Hanson have tried to separate the impact of trade from other factors affecting U.S. manufacturing employment and they estimate that between 1990 and 2007 Hickory lost 16 percent of its manufacturing jobs just due to surging imports from China. DEEP SCARS. Buffeted by other headwinds, such as the 1994 North American Free Trade agreement and the lifting of textile quotas in 2004, the area lost 40,000 manufacturing jobs overall, half the total, between 2000 and 2009. Nationally, more than 5 million manufacturing jobs have disappeared since 2000, a period that also included the worst economic downturn since the Great Depression. The collapse left deep and still visible scars that help explain the appeal of Trump's pledge to bring back manufacturing's glory days. In Hickory, disability rolls soared more than 50 percent between 2000 and 2014, swollen by older workers who struggled to return to the workforce. At the same time, the share of the 25-34 year old in the population fell by almost a fifth between 2000 and 2010. Consequently, even as the unemployment rate tumbled from a peak above 15 percent in 2010 to 4.6 percent today, below the national average, so did the labor force participation rate. It fell from above 68 percent in 2000 to below 59 percent in 2014. Poverty levels doubled. Yet the manufacturing upswing in areas that suffered the most during the downturn is evident. Rust belt states, such as Michigan, Indiana and Ohio that may prove pivotal in the Nov. 8 presidential election, have been adding manufacturing jobs faster than the economy as a whole. Michigan, for example, which lost nearly half of its manufacturing jobs between 2000 and 2009, has since then seen a 25 percent rise, well above the 4 percent gain nationally. Manufacturing employment there is still well below the levels in the 1990s. Economists debate whether returning to that level is realistic given technological advances that have reduced manufacturing's share of the workforce from a high of above 30 percent in the 1950s to around 8 percent today. But they also feel that have already seen the bottom, particularly when it comes to China's impact.

  4. Ryan Bathrick:

    Leaf rust was an effect of climate change.

  5. Alfred Lord Tennyson, Ulysses (poem):

    How dull it is to pause, to make an end, To rust unburnished, not to shine in use!
