2. Pickling (metal) - Wikipedia

   en.wikipedia.org/wiki/Pickling_(metal)

   Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, and rust or scale from ferrous metals, copper, precious metals and aluminium alloys. [1] A solution called pickle liquor, which usually contains acid, is used to remove the surface impurities.

3. Chrome plating - Wikipedia

   en.wikipedia.org/wiki/Chrome_plating

   Hard chrome plating. Hard chrome, also known as industrial chrome or engineered chrome, is used to reduce friction, improve durability through abrasion tolerance and wear resistance in general, minimize galling or seizing of parts, expand chemical inertness to include a broader set of conditions (such as oxidation resistance), and bulking ...

   Unlike most acid-based rust removers, POR-15–short for Paint Over Rust–not only melts away rust, but preps the metal underneath for paint by lightly etching the metal and leaving behind a zinc ...

6. Passivation (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Passivation_(chemistry)

   These industry standards generally list several passivation processes that can be used, with the choice of specific method left to the customer and vendor. The "method" is either a nitric acid-based passivating bath, or a citric acid-based bath, these acids remove surface iron and rust, while sparing the chromium. The various 'types' listed ...

7. Chromate conversion coating - Wikipedia

   en.wikipedia.org/wiki/Chromate_conversion_coating

   Chromate conversion coatings are usually applied by immersing the part in a chemical bath until a film of the desired thickness has formed, removing the part, rinsing it and letting it dry. The process is usually carried out at room temperature, with a few minutes of immersion.

8. Zinc flake coating - Wikipedia

   en.wikipedia.org/wiki/Zinc_flake_coating

   The typical cleaning processes are removal with an alkaline aqueous solution and then blasting with very small steel balls (shot). Cleaning solutions remove grease, oil and dirt from the metal surface. Blasting removes scaling and rust through the mechanical action of the steel balls, which are fired at the parts inside a chamber using a turbine.

9. Rust converter - Wikipedia

   en.wikipedia.org/wiki/Rust_converter

   Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...
