he treatment of metal surfaces with a strong oxidising agent such as nitric acid, to make them chemically clean and provide a strong, inert oxide film.

Treating the surface of iron or steel with acid to remove scale, rust and dirt, preparatory to further processing such as cold rolling, tinning, galvanizing, polishing, etc.

The process of removing oxide scale from forgings by treating in a heated acid bath.

An operation by which surface oxide (scale) is removed by chemical action. Sulfuric acid is typically used for carbon and low-alloy steels. After the acid bath, the steel is rinsed in water.

Is where vegetables like cucumbers or seafood like prawns are "pickled" in sugar, vinegar and spices for a day or two before eating.

The practice of adding enough vinegar or lemon juice to a low-acid food to lower its pH to 4.6 or lower. Properly pickled foods may be safely heat processed in boiling water.

Using a heated acid bath to remove oxide scale from forgings.

Removal of oxides or other compounds of the basis metal from a metal surface by chemical or electrochemical action.

The removal of oxides (rust) with acidic materials.

Immersion of steel in a dilute solution of acid for the purpose of removing the scale.

Chemical or electro-chemical removal of surface oxides.

passing steel through an acid bath to remove hot mill scale and oxide from the surface

The process of chemically removing scale, oxide and other foreign material from steel to obtain a chemically clean surface. Hydrochloric acid is the cleaning agent generally employed.

The use of a chemical solution to prepare a surface for coating or bonding by dissolving away surface oxides and other impurities -- a certain amount of base metal may also be removed.

Chemical or electrochemical removal of oxides from the surface of metals.

Removing surface oxides from metals by a chemical reaction.

Pickling is the process of using various acids and acid mixtures to remove scale that can form on material during processing at elevated temperatures (such as hot rolling or annealing).

an acid was h that gets rid of black rust.

The liquid process of removing surface oxide and scale from metal which has been hot worked.

Pipe immersed into acid bath for removal of scale, oil, dirt, etc

A preliminary process for preparing hides and skins for tanning, largely by adjusting the pH with acid and controlling the swelling with salt. It is also use as stable way of holding material, after unhairing, for transport between plants and countries and for trading.

Removing surface oxides from metals by chemical or electrochemical reaction.

The removal of surface oxides from metals by immersion in a reducing acid bath. Occasionally a blackish surface smut (a non-adhering carbon film) is produced which must be removed by scrubbing or immersion in an oxidizing acid bath.

The removal of scale by treatment with diluted acids or other chemicals.

A mild acid bath treatment to dissolve the surface oxidation of metal which occurs when metal is heat treated in open air rather than atmosphere controlled conditions. Essentially a cleaning process.

A process of chemically removing scales and oxides from metal by passing it through a chemical solution. See pickle.

The treatment of steel for the removal of rust and mill scale by immersion in a hot acid solution containing an inhibitor.

A process that removes surface scale and oxidation products by immersion in a chemically active solution, such as sulfuric or hydrochloric acid.

A process to chemically remove scale or oxide from steel to obtain a clean surface. When applied to bars or coils prior to bright drawing, the steel is immersed in a bath of dilute sulfuric acid heated to a temperature of around 80oC. An inhibitor is added to prevent attack and pitting of the cleaned metal. After pickling, a washing process takes place followed by immersion in a lime-water bath to neutralize any remaining acid. For environmental reasons shot blasting has largely replaced pickling.

A chemical or electrochemical method of removing mill scale, rust, metal oxides and similar coatings from steel.

A treatment for the removal of rust and millscale from steel by immersing in an acid solution.

A chemical bathing procedure used to remove the oxide film on a titanium product.

Process for chemical treatment of oxidized steel, applied to obtain a clean metallic surface.  Here, the steel is dipped into a hot bath of diluted sulphuric or hydrochloric acid.

Pickling is name given to the process of cleaning a steel coil through a series of hydrochloric acid baths that remove the oxides (rust), dirt, and oil so that further work, such as roll forming, can be done to the metal.

The process of removing surface oxide and scale from copper alloys with a mill pickle solution consisting of approximately 12 to 15 percent sulfuric acid in water by volume.

Immersing a positive lead plate into a diluted sulfuric acid solution. A process in which specific plate types are saturated in sulfuric acid after pasting. The saturation produces a protective surface and a supply of sulfate which supports container and tank formation.

(slang) The preservative treatment of wood, metals, and piping systems.

Removing scale by immersion in a dilute acid bath.

The process of adding salt and sulphuric acid to hides to transform them into an acid environment for tanning.

A process of removing iron oxide from hot rolled bands by immersion in acid solution prior to cold reduction.

Acid washing a metal surface to remove corrosion, clean or restore old metal, or to minimize future corrosion.

WHAT Process that cleans a steel coil of its rust, dirt and oil so that further work can be done to the metal. WHY When hot-rolled coils cool, rust forms on the unprotected metal; often coils are stored or transported while exposed to outside air and water. HOW Through a continuous process, the steel is uncoiled and sent through a series of hydrochloric acid baths that remove the oxides (rust). The steel sheet is then rinsed and dried.

Pickling, or corning, is the process of preparing a food by soaking and storing it in a brine containing salt and/or acid (usually vinegar), a process which can preserve perishable foods for months. The resulting food is called a pickle.

Pickling is a treatment of metallic surfaces in order to remove impurities, stains, or scales with a solution called pickle liquor before subsequent processing, such as extrusion, rolling, and galvanizing.

The process of rubbing white paint into previously finished wood.

Applying a very transparent glaze of color to a wood surface, in essence "staining" it with color which allows the wood grain to show through. Easily accomplished by mixing 2 parts varnish with one part water then tinting with color of choice.

A term for a piece of wood that's been limed. Also a method of painting furniture and then wiping off the paint before it has completely dried leaving some on the edges.

A method used to give wood a whitish cast.

A technique of using thinned, transparent paint to give wood a "washed out" appearance, with the wood grain showing through.

A process of rubbing white paint or chemicals into previously finished wood.

A whitewashed paint finish.
