Overview Electropolishing is an electrochemical process that removes material from a metallic work piece. It is used to polish, passivate, and deburr metal parts and is often described as the reverse of electroplating. Application Electropolishing has many applications in the metal finishing industry because of its simplicity and it can be applied to objects of…

Overview Originally developed as an alternative to hexavalent chrome finishing, this coating has been widely embraced in the marketplace. With its ability to uniformly coat complex shapes without the need for post grinding, Nickel Boron offers outstanding results. Nickel Boron has unique properties, along with excellent hardness, wear, and abrasion characteristics. It has become the…

Overview Electroless Nickel Plating is the deposition of a nickel-phosphorous alloy onto a metal substrate without the use of an electrical current. The electroless nickel plating process utilizes an autocatalytic chemical reaction to deposit a reliable, repeatable coating of uniform thickness. This uniformity of deposit eliminates the need for post-plate grinding. Electroless nickel demonstrates excellent…

Overview Chemical conversion coatings sometimes referred to as chromate conversion, chem film, Iridite or Alodine refer to a process of applying a thin barrier coating on the substrate to passivate aluminum alloys to slow the formation of corrosion. It is gelatinous film that has self-healing properties and improves paint adhesion on aluminum alloys and die…
