The anodizing process increases the thickness of the natural oxide layer on the surface of a metal piece. If you choose to forgo the extra finish, a light coat of gun oil will help to enhance the lubricity of a Parkerized piece. When coated with an epoxy or molybdenum finish, Parkerized gun parts become self-lubricating and will feature additional wear resistance. Depending on the ingredients, a phosphatized piece of metal will range in color from medium-gray to black. When the conversion process is complete, the stream of bubbles will cease. Picture: Spike's Tactical Parkerizied (Phosphate) Bolt Carrier Groupĭuring the gun Parkerizing process, streams of tiny bubbles will rise from the metal part as the reaction takes place. The solution is then heated to 190 to 210 degrees Fahrenheit. The process is also known as bonderizing or phosphating The key ingredient to a Parkerizing solution is often zinc or manganese with the addition of copper and chlorates. Gun Parkerizing helps protect a steel surface from corrosion and increases its resistance to nicks and scratches by the submersion of the steel into a phosphoric acid solution. This process initiates a reaction that converts any rust-tending metal to magnetite and effectively kills the rust process before it can even begin. Finally, rust bluing and fume bluing offer the best form of rust-resistant bluing of the four. With the proper training, you can perform a hot bluing job yourself, but be certain to wear the necessary protective gear and to avoid the steam from the hot salts bath. This process was developed to speed up the bluing procedure for factories and lends a beautiful, gray-blue finish to the completed project. The process is performed at temperatures of 275 to 311 degrees Fahrenheit. The second process is hot bluing and uses alkali salt. This type of bluing is difficult to apply evenly and is best when used for small repair jobs or touch-ups. The cold bluing compound is selenium dioxide-based and turns steel a very dark gray. Each of these processes are slightly different. The bluing process for guns will also allow a decrease in the glare effect of a treated piece.īluing can be referred to by many names, including cold bluing, hot bluing, rust bluing and fume bluing. A black oxide coating will not cause a dimensional change of the treated object and is one of the cheapest coating options available. Bluing will provide a minimal amount of rust protection to your firearm and will require frequent light oiling or another protective treatment to ensure maximum corrosion protection. Bluing guns are achieved by an electrochemical process in which the iron in steel is converted to magnetite, or black oxide. Steel bluing, also known as gun bluing, oxidizing and black passivating, is a process by which the metal is given a rust-resistant finish. For further information, read on and learn about six different gun part coating options: bluing, Parkerizing, anodizing, Cerakote, nickel boron and ferritic nitrocarburizing. Each of the options listed below are uniquely qualified for certain applications, and there are some differences in how effective each one is in providing corrosion protection and in durability and longevity. The type of coating you choose will depend on a few factors: how much you’re willing to spend, the quality of the piece to be treated and the expected environment in which you intend to use your firearm. Each of these have its own unique benefits and properties. There are many coating options available for the gun owner of today ranging from bluing to Tenifer™ to Cerakote.
