The sulfuric acid process is the most common method for anodizing. The sulfuric acid anodize process films range from .0001″-.001″ thick. The overall thickness of the coating formed is about 67 percent penetration in the substrate and approximately 33 percent growth over the original dimension of the part. It is particularly suited for applications where hardness and resistance to abrasion is required.

Hardcoat Anodize or simply Hard Anodize is a dense anodic coating of aluminum oxide applied by converting a properly cleaned and deoxidized aluminum alloy component into an oxide film using a suitable electrolyte, typically sulfuric acid cooled to nearly freezing, and applied voltages upwards of 100 volts at an applied current density of 24-36 amps per square foot.

Electroless Nickel Plating is the deposit of a nickel-alloy coating by chemical reduction – without the electric current that is used in electroplating processes. It is also sometimes called autocatalytic because the metal being applied is in solution and adheres itself to the substrate (plastic or ceramic included) without the use of an outside power source.

Passivation is used to clean and improve the surface condition of stainless steel by dissolving the large or small rust spots that can appear as a by product of machining or other manufacturing steps. In order to prevent corrosion appearing on stainless steel parts, passivation treatment is recommended.

Conversion coatings is a generic term used to refer to a coating produced by a chemical or electrochemical treatment of a metallic surface. Chromate conversion coatings are a varying group that can be done as a stand-alone finish, used by itself, or as a secondary post finish treatment.

Black Oxide is a conversion coating formed by a chemical reaction with the iron in the metal to form an integral protective surface.  Bead blasting is a process in which small spheres of glass or other abrasive material are blasted at high pressure against a surface.
