Electroless Nickel Plating For Longer Wear & Corrosion Resistance
What Is Electroless Nickel?
As the process name implies, an Electroless Nickel deposit is not the result of a standard electroplating process, but rather the result of a chemical reaction that deposits a coating of Nickel and Phosphorous on this surface.
An Autocatalytic Chemical Reaction
The reaction is autocatalytic: once it starts, the presence of nickel acts as a catalyst to keep the reaction going. Deposit thicknesses can range from a few microns to 100 microns.
Typical Uses Of Electroless Nickel By Industry
Electronics IndustryMost media storage disks in computers are made of Aluminum and plated with Electroless Nickel. Many other components such as on connectors also find electroless nickel to be a very useful finish.
Automotive IndustryAs an undercoat on many decorative trim pieces that are made out of Aluminum (subsequently Cr plated). Also used for wear resistance on brake components and gears in response to the need for longer warranties.
Oil Industry & Gas IndustryPrimarily used for corrosion resistance, although wearability is also a consideration. Valve components, pumps and pipe fittings are typically electroless nickel plated.
Chemical Processing IndustryUsed for mixing blades, pumps, etc.
Equipment components of all types.
Phosphorous Content Categories
Electroless Nickel deposits are divided into three categories, based upon Phosphorous content.
- Low Phosphorous 1-3%
- Medium Phosphorous 4-9%
- High Phosphorous 10-13%
Unique Properties Of Electroless Nickel Deposits
- Because the deposit is the result of a chemical reaction, uniform deposits are obtained over all surfaces.
- The Phosphorous content makes the deposit somewhat self-lubricating.
- As a general statement, the lower the Phosphorous content, the higher the as-deposited hardness. However, the lower the Phosphorous content, the lower the corrosion resistance.
- All Electroless Nickel coatings can be hardened by heat treatment after deposition. Nickel Phosphide forms through a process known as precipitation hardening.
