(Anodising) Anodising, or anodizing, is a process used to protect aluminum from abrasion and corrosion and to allow it to be dyed in a wide range of colors. The process derives its name from the fact that the part to be treated forms the anode portion of an electrical circuit in this electrolytic process. ...more on Wikipedia about "Anodising"
Bluing is a process in which steel is partially-protected against rust, and is so-named after the blue-black appearance of the resulting protective finish. True gun bluing is a conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite (Fe304), the black oxide of iron, which occupies the same volume as normal iron. Black oxide provides minimal protection against corrosion, unless also treated with a water-displacing oil. In contrast, the red oxide of iron, Fe2O3 does not occupy the same volume as iron, thereby causing the typical reddish rusting away of iron. Both "cold" and "hot" oxidizing processes are called bluing, but only the "hot" process provides any rust and corrosion resistance, and then only when also treated with an oiled coating. ...more on Wikipedia about "Bluing (steel)"
Cathodic protection (CP) is a technique to control the corrosion of a metal surface by making that surface the cathode of an electrochemical cell. ...more on Wikipedia about "Cathodic protection"

Chrome plating is a finishing treatment utilizing the electrolytic deposition of chromium. The most common form of chrome plating is the thin, decorative bright chrome, which is typically a 10 µm layer over an underlying nickel plate. It imparts a mirror-like finish to items such as metal furniture frames and automotive trim. Thicker deposits, up to 1000 µm, are called hard chrome and are used in industrial equipment to reduce friction and wear and to restore the dimensions of equipment that has experienced wear. ...more on Wikipedia about "Chrome plating"
A corrosion inhibitor is a chemical compound that, when added in small concentration, stops or slows down corrosion of metals and alloys. ...more on Wikipedia about "Corrosion inhibitor"
Electroplating is the coating of an electrically conductive item with a layer of metal using electrical current. The result is a thin, smooth, even coat of metal on the object. ...more on Wikipedia about "Electroplating" Good to know http://www.shortopedia.com. shortopedia

Gold plating is a method of depositing a thin layer of gold on the surface of other metal, most often copper or silver, by chemical or electrochemical means. Mechanical or chemical affixing of thin gold foils on the surface of objects is instead known as gilding. ...more on Wikipedia about "Gold plating"
Hot-dip galvanizing is a form of galvanization. It is the process of coating iron or steel with a thin zinc layer by passing the steel through a molten bath of zinc at a temperature of around 460°C. Zinc "rusts" to form zinc oxide, a fairly strong material that stops further rusting, protecting the steel below from the elements. Galvanized steel is widely used in applications where rust resistance is needed, and can be identified by the crystalization patterning on the surface (often called a "spangle"). ...more on Wikipedia about "Hot-dip galvanizing"
Parkerizing (also called phosphating) is a method of protecting a steel surface from corrosion and increasing its resistance to wear. It is commonly used on firearms as a more effective alternative to bluing. However, the process cannot be used on non-ferrous metals such as aluminum, brass, copper or stainless steel. ...more on Wikipedia about "Parkerizing"
Passivation is the process of making a material "passive" in relation to another material prior to using the materials together. For example, prior to storing hydrogen peroxide in an aluminium container, the container can be passivated by rinsing it with a dilute solution of nitric acid and peroxide alternating with deionized water. The nitric acid and peroxide oxidizes and dissolves any impurities on the inner surface of the container, and the deionized water rinses away the acid and oxidized impurities. ...more on Wikipedia about "Passivation"
Plasma electrolytic oxidation, or microarc oxidation, is an electrochemical surface treatment process for metals. It is similar to anodising, but it employs higher potentials, so that discharges occur. This process can be used to grow thick (10s or 100s of micrometres), largely crystalline, oxide coatings on metals such as aluminium, magnesium and titanium. Because they can present high hardness and a continuous barrier, these coatings can offer protection against wear, corrosion or heat as well as electrical insulation. ...more on Wikipedia about "Plasma electrolytic oxidation"
