What is a rust trombone?

A rusty trombone is slang for a specific sexual act: namely, where a female performs an act of oral stimulation on the ... um ... rear-area of a man while simultaneously using her hand on the front side of the male.   (How's that for a relatively clean explanation? LOL)

There are a vast number of water soluble corrosion inhibitors.\n\nAt the simple end of the scale - Sodium nitrite, sodium tolytriazole, zinc phosphate, borates, molybdates, vanadates and chromates all inhibit rust.\n\nThere are also proprietary organic compounds (some phosphate esters, ethanolamides, etc) also inhibit rust.\n\nIt all depends on whether you want the inhibition to be short lived or long lived (nothing is "permanent") and whether the inhibition is an "in use" inhibitor (like, say, a corrosion inhibitor in cooling water) or "static" (like phosphate "rust converters" used prior to painting.

My guess would be Duraluminium (an Aluminum alloy) orsome sort of titanium alloy... \n\nDuraluminium is used in harddisks as the ring separating the platters and in expensive bikes.

Rust is a chemical reaction involving iron and oxygen.  Melting metal is simply a physical reaction changing the state of its matter, so melting the metal wouldn't get rid of the rust to the best of my knowledge.  IT might however make it easy for you to seperate the rusted and non rusted parts of the metal, but then again it might make it a total mess lol

Rusting of iron is an oxidation/reduction process which means there is a transfer of electrons.  Any soluble ionic compound will facilitate the transfer of the electrons and accelerate the oxidation process.

I am not sure about rust, but I know that each 12 ounce can of Coke contains 10 teaspoons of sugar.  (That is what my chemistry college professor told me).

Dulcimer\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\n \nThe hammered dulcimerDulcimer is the name given to two types of stringed musical instrument:\n\nThe Appalachian dulcimer, a fretted, plucked instrument which is also referred to as a mountain dulcimer or just a dulcimer, and \nThe Hammered dulcimer, which is a hammer-struck, trapezoid-shaped zither \nThe instruments are quite different, but are both members of the zither family of instruments.

When iron turns to rust, the resulting rust is heavier than the original object.

Calcium/ rust buildup. First, you can try ordinary vinegar. Take off the head and soak the piece in vinegar overnight. That may dissolve the calcium. If not, try CLR or similar product, they work wonders!

corrosion is caused by the chemical reaction of oxygen with the metal over time, thus causing rust.  In order to help preserve the metal, a layer of paint is used that will serves as a shield or barrier between the oxygen and the metal.

The Pedersen bicycle of the early 20th Century famously features such a saddle. A company called Dursley manufactures replicas of the amazing and attractive Pedersen design. Its a lovely, early example of suspension.\n\nTo see examples of Pedersen bikes type 'pedersen bicycle' into Google and select Images.

Rusting is a type of oxidation.  Iron forms a compound with oxygen, iron(III) oxide or ferric oxide, which we call rust.\n\nA screw can be made from steel, aluminum, titanium, bronze, or even plastics like Teflon or nylon.  A screw can be made from pretty much any structural material.

Articles from the HTPAA Quarterly Publication - Tool Chest  \n\nFeatured Article on Rust Removal\nPart 1 - Electrolysis\nHome  \nElectrolytic Removal of Rust \n\nby Kevin Chamberlain, Member HTPAA ( published in Tool Chest #63, February 2002) \n\nIntroduction \n\nAt our last Tool Conference, there was a Panel Discussion dealing with the cleaning and restoration of old hand tools. This is a key concern for anyone interested in collecting old tools, since one rarely finds tools in mint condition in an original box. It is much more common to find tools showing the combined effects of correct usage, abuse, neglect and simple ageing. The primary question is: should cleaning and/or restoration be attempted at all?\n\nThe answers are conflicting; some aim to restore the tool to a brand-new appearance, eliminating all evidence of its life history. Others think any attempt at restoration will destroy the character and value of an antique tool. \n\nMost think some intervention is desirable to remedy the effects of abuse and neglect, while still retraining as much patina and character as possible. There is an important caveat - "when in doubt, do nothing". Cleaning and restoration of antique tools should be done in a careful and meditative mood - otherwise rash actions may cause loss of valuable information and/or further damage. \n\nRemoval of rust from old tools or other artefacts may or may not be a desirable goal. In some cases (museum specimens) stabilization to prevent further deterioration may be all that is necessary. Rust may be regarded as undesirable by tool users or collectors because it obscures identifying marks, causes seizure of moving parts, creates an unpleasant rough texture to the touch, stains the hands and/or the workpiece, or is simply unsightly. I believe rust removal is often justified, but the method chosen should not alter the surface in other ways and should result in a reasonably attractive surface appearance.\n\nThe electrolytic method of rust removal meets these aims very well and is also a gentle, cheap and adaptable method. Electrolysis is now being used by a wide range of artefact restorers, from tool collectors to marine archaeologists. \n\nIn this article, I mainly aim to outline the practical aspects of the electrolytic method so that members can try it for themselves. Several HTPAA members have been using the method for some years and find it very useful\n\nWhat is Rust? \nRust arises from the surface oxidation of iron or steel in the presence of atmospheric oxygen and moisture. As the rust forms, the surface of the iron is eaten away, sometimes evenly, but often deep local pitting occurs beneath wart-like protuberances. Rust occupies more volume than the iron it replaces, and so moving parts will tend to seize as they rust. \nChemically, most red rust is hydrous ferric oxide FeO(OH). If water enters this chemical structure, yellow-brown limonite may form FeO(OH).nH2O. Quite often, black iron oxides are also present usually magnetite (Fe3O4), an iron oxide which both conducts electricity and can be magnetised. The rusting process, and the conditions which promote, inhibit or stabilise it, are all important topics which are beyond the limits of the present article. \n\nMethods of Rust Removal\nRust usually binds strongly to the underlying iron or steel. Various methods have been used to remove rust. Mechanical methods include the use of emery paper, sandpaper or wire brushes (either manual or powered). More aggressive methods include sand blasting or shot blasting. Plastic bead blasting is a more recent and gentler variant. Clearly these methods will scratch the metal surface if the abrasives are harder than the metal. Wire brushes, for example, do not appear to scratch hard steel surfaces but they can be quite damaging to soft iron surfaces. \n\nGas flames are sometimes used to dislodge rust, relying on the different expansion rates of the oxides and the metal in response to heat.
