Industry Information
View A Video on Electroless Nickel Plating - A Quick Introduction

Electroless nickel (EN) plating is an auto-catalytic chemical reaction that results in a layer of nickel alloy, typically nickel-phosphorus or nickel-boron, to be deposited onto a solid substrate like a metal or plastic workpiece. A reducing agent, such as hydrated sodium hypophosphite, is crucial to the electroless nickel plating process because it reacts with the metal ions and allows for the nickel to be deposited.

A comparative metal plating process to electroless nickel plating is electroplating, which utilizes an electrical current in order to achieve the same process that electroless plating is capable of achieving without electricity. Electroless nickel plating, also at times referred to as nickel coating, is a common industrial process and can be utilized in several other industries including: petroleum, in which it is used on essential components such as oil field valves and fuel rails; automotive, used to plate power transmission parts such as drive shafts; residential, used in coating kitchen utensils, door knobs, bathroom fixtures and more; and electronics, in order to plate electric components such as hard drive disks and printed circuit boards (PCBs). Although nickel is the most common material that is utilized in electroless plating processes, it is not the only type of material that can be electroless plated.


Additional materials that can be used electroless plating processes include: gold, silver, tin, zinc, copper, chrome, cadmium, palladium and rhodium. Of these material types and after nickel of course, the most commonly used in electroless plating processes are gold, silver, copper and palladium. In gold plating, a thin layer of gold is deposited on the surface of another metal, this most often occurs in electronics in order to provide other metal's with a corrosion-resistant and electrically conductive layer. Similarly used, silver plating is often utilized in the electronics industry as a less-expensive alternative to gold plating. However, silver-plated parts will not perform well in humid environments because of it does oxidize. Also used in the electronics industry, copper plating does not perform quite as well as either gold or silver, but is a much less-expensive option than either. In addition, copper has a higher conductivity than comparable other metals such as aluminum. Although palladium is not a common metal, in fact is a rather rare metal with a lustrous silvery-white color only discovered in 1803, one of its more common uses is that of electroless plating. Palladium works so well for electroless plating because it provides such excellent bath stability as well as a high corrosion resistance.

In addition to the more common metals used in electroless nickel plating, there are those that are widely used in electroplating, but not so widely used in electroless plating including tin, zinc, chrome, cadmium and rhodium. Electroless tin plating is also commonly utilized in the electronics industry, specifically for PCBs. Tin is typically alloyed with other metals such as lead or copper before it is used for electroless plating. Electroless zinc plating prevents oxidation of the plated metal. In addition, zinc is typically used in electroless barrel plating processes, which means that small parts are electroplated in large groups. Electroless chromium (EC) plating, or chrome plating, actually refers to an alloy of chromium rather than pure chromium, which can be very expensive and requires an electrical current in order to be plated. Electroless cadmium plating is not an incredibly common process because it is under some scrutiny because of some side-effects of the process with the metal that could potentially be hazardous to the environment. However, electroless cadmium plating remains widely used in the aerospace and military industries. Lastly, there is electroless rhodium plating, which is typically used on precious metals such as gold and silver for commercial applications such as jewelry.

The electroless plating process, which is also known as autocatalytic plating, is essentially a chemical reaction. In this chemical reaction, the metal being deposited onto the workpiece is immersed in an aqueous solution that is often referred to as a bath solution. Without using an external electrical power supply, the metal reacts instead as a result of the introduction of a reducing agent into the bath solution. The reducing agent, typically sodium hypophosphite, functions to release hydrogen and consequentially reacts with the metal ions of the material being deposited producing a negative surface charge and resulting in deposition. Contrastingly, the electroplating process uses an electrical current in order to reduce cations of a desired material from a solution instead of a chemical solution. When the reduction of cations occurs, a conductive object is coated with a thin layer of the typically metallic material. The electroplating process is primarily used for the deposition a layer of metal in order to provide the material being plated with a desirable property such as abrasion and wear resistance, corrosion protection, lubricity or aesthetic qualities that it would not otherwise have. Another application of electroplating is to build up the thickness of undersized parts.

Electroless Nickel Plating Types

  • Cadmium plating is the process of depositing a thin, uniform layer of cadmium onto another substrate, such as a metal or plastic workpiece.
  • Chrome plating is a finishing treatment that can be either bright chrome or hard chrome.
  • Copper plating is the process of depositing a layer of copper onto a solid metal or plastic workpiece.
  • Composite coatings use hard particulate matter mixed with electroless nickel plating chemicals. Silicon carbides and synthetic diamonds are common types of composite materials.
  • Electroless nickel/Teflon® composite plating creates a slick, low friction surface.
  • Electroless plating, also known as chemical or auto-catalytic plating, is a type of plating that does not use electricity.
  • Electroplating is an alternate type of the coating/plating process. Using a low voltage current, charged nickel compounds are attracted to a substrate's oppositely-charged surface; in this fashion, nickel deposits are transferred through a solution and onto the substrate. 
  • Gold plating involves the deposition of a thin layer of gold onto another substrate, typically a variety of metal parts.
  • High phosphorous plating has the best corrosion resistance of any electroless nickel plating process. It is used in harsh environments, such as oil drilling and coal mining.
  • Low phosphorous (hard) plating yields very good resistance to alkaline corrosive environments. It also provides uniform thickness, so that grinding after the procedure is unnecessary.
  • Medium phosphorous (bright high speed) plating is a popular form of nickel plating that has been used over the years. It generates a nice uniform coating and will not build up on the edges of the substrate.
  • Metal finishers improve a product's corrosion and wear resistance.
  • Metal-plating is the process of depositing a metal or metal alloy onto a surface.
  • Nickel-boron coatings are admired for their as-plated hardness, which is greater than that of nickel-phosphorus platings. The melting point for N-B alloys is higher than that of N-P, but chemical costs for nickel-boron baths can be up to 10 times that of the nickel-phosphorus chemicals.
  • Nickel coating is the process of coating an item with a nickel alloy to prevent oxidation.\
  • Nickel plating is the process of depositing a thin layer of nickel onto another substrate, such as metal or plastic.
  • Poly alloy coatings consist of nickel and boron or phosphorus. Other materials, such as iron, cobalt and tungsten, are also included in poly alloys. Polly alloy coatings allow maximum corrosion and high-temperature resistance, hardness and magnetic or nonmagnetic qualities.
  • Rhodium plating refers to the process of depositing a thin layer of the chemical element rhodium (Rh) onto a conductive metal surface.
  • Silver plating is the process of coating another substrate with a thin layer of silver.
  • Tin plating is the deposition of tin onto another material's surface, both ferrous and non-ferrous, in order to provide increased protection from harsh conditions.
  • Zinc plating is an industrial process that utilizes either solely a chemical reaction of a combination of a chemical reaction and an electrical current in order to deposit a thin coating of zinc onto a metal part.
