Electroless Nickel (EN) plating is unique in that it does not require electrical charges which can result in inconsistent deposits. Instead, the EN process relies on the presence of chemical reduction agents that react with the metal ions to deposit a thin, uniform nickel coating on solid workpiece.
Nickel brush plating is an electrochemical metallizing process in which the high current density technology of arc welding is applied to a concentrated electrolyte solution thus depositing metal without the use of either heat or immersion tanks.
Cyanide plating means plating processes performed in tanks using cyanide as a major bath ingredient and operating at pH of 12 or more, and use or emit any of the plating and polishing metal HAP. Electroplating and electroforming are performed with or without cyanide. The
Zinc Electroplating CHOOSING THE BEST PROCESS FOR YOUR OPERATION By Clifford Biddulph Pavco Inc. 107 ZINC ELECTROPLATING PLATING/ANODIZING. 108 2011 PF DIRECTORY ZINC ELECTROPLATING PLATING/ANODIZING TABLE I— Attributes of Zinc Electroplating Processes
Electroplating, process of coating with metal by means of an electric current. Plating metal may be transferred to conductive surfaces (metals) or to nonconductive surfaces (plastics, wood, leather) after the latter have been rendered conductive by such processes as coating with graphite, conductive lacquer, electroless plate, or a vaporized coating.
Nickel plating was first performed by in 1837, but it was not until 1868 that Adams, having made many improvements, was able to put the process into commercial operation. Zinc and copper electrodeposition were developed over the same period.
Types of Nickel Plating KPW Offers. Bright nickel plating offers a bright lustrous finish used for decorative and corrosion protection purposes.. Semibright nickel plating is somewhat of a bright deposit with excellent ductility.. Nickel chloride is a dull nickel used in the pretreatment of stainless steels.
Apr 25, 2017· Electroless plating, so called because the process uses no external power, involves an aqueous solution in which several chemical reactions take place simultaneously. Sodium hypophosphite, or another reducing agent, releases hydrogen as hydride ions, which produce a negative charge on the steel to be plated.
Electroless nickel plating is an autocatalytic reaction used to deposit a coating of nickel on a substrate. Unlike electrolytic nickel and electroplating, it is not necessary to pass an electrical current through the solution to form a deposit.
ELECTROLESS DEPOSITION AND ELECTROPLATING OF METALS INTRODUCTION Alongside with multipurpose procedures of lowtemperature metal deposition by electrochemical reduction of their soluble compounds, there is a possibility for electroless reduction of .
Nickel Plating. Nickel plating can be used as a standalone finish or as a base layer for subsequent plating processes. Like chrome plating, nickel can be used for both industrial and decorative applications. For decorative applications, nickel can produce a dull, matte color for a satin finish or brightener may be added to produce a shiny mirror finish.
Modern electroplating is a form of metal finishing used in various industries, including aerospace, automotive, military, medical, RF microwave, space, electronics and battery manufacturing. It is the electrochemical process whereby metal ions in solution are bonded to a metal substrate via electrodeposition.

Our processes provide essential functionality to the enduse markets
Sinotech is dedicated to managing your project onsite and delivering parts to you at lower prices but the same quality, service and terms as a domestic supplier. Autocatalytic (Electroless) plating, also known as electroless plating, is a plating process which involves deposition without any current applied. The process is a chemical reaction and is autocatalytic.
Electrolytic nickel plating is an electroplating process that uses electrical current with dissolved chemical baths to form a coherent metal coating on a part to change its surface properties such as corrosion protection. MFI offers inhouse electrolytic nickel plating to .
The electroless copper deposition process developed in this study may open up a new route of plating on plastics (POP) for printed circuit boards, electromagnetic interference shielding, and many ...
Electroless Nickel Plating creates a uniform, hard coating for either steel or aluminum parts. Because our nickel plating process is autocatalytic (electroless), it ensures that all surfaces and blind holes, even on irregular shaped parts, are plated with an even layer of nickelphosphorus that is less porous than electroplated nickel.

Selective (brush) plating is an approved low hydrogen embrittlement (LHE) process used to apply zincnickel onto localized areas of high strength steel components for corrosion protection. It is used to apply localized deposits onto previously unplated parts as well as .
NICKLON™ is the goto in many applications. It offers corrosion and oxidation protection equal to Electroless Nickel, with excellent lubricity and wear resistance due to the codeposit of Electroless Nickel .
Electroless Plating. The electroless nickel process provides a unique combination of high quality, rapid throughput and turnround with superb performance due to its unique characteristics primarily achieved due to its lack of need for an electric current. The process hasn't been around as long as Electroplating but since being discovered in 1946 has...
This process specification establishes technical requirements for the application of electrodeposited nickel plating on steel, copper and copper alloys, and zinc and zinc alloys. This process specification applies to the electrodeposition of nickel plating on substrates of steel, copper, zinc, and their alloys.
Nickelchrome plating. Also called decorative chrome plating, nickelchrome plating involves electroplating a thin layer of nickel onto the item before the chrome layer is plated onto it. Copper may also be electroplated on the item prior to the application of the nickel. The layer of nickel adds smoothness, reflectivity and corrosion resistance.
Electroless Nickel Immersion Gold (ENIG) ENIG is another surface plating process used on circuit boards and LTCC surface finishes. The ENIG plating consists of an Electroless nickel deposition ( – 3 um) followed by a thin layer of immersion gold ( to 2 um), to protect the nickel from oxidation.
May 16, 2017· Electroplating is the process of applying a metal coating on another piece of metal (or another conductive surface) through an electrodeposition process. In electroplating, the deposited metal becomes part of the existing product with the plating/coating.
