Electroless Nickel Plating

First developed in the 1940s electroless nickel en plating is used heavily by automotive and aviation for corrosion and wear resistance.

Electroless nickel plating.

Electroless nickel ptfe plating electroless nickel ptfe teflon is an advanced self lubricating composite coating that has ptfe particles co deposited in the electroless nickel layer. It is a coating with multi functional properties. Below is a brief overview of the electroless. Electroless nickel phosphorus plating is a chemical process that deposits an even layer of nickel phosphorus alloy on the surface of a solid substrate like metal or plastic the process involves dipping the substrate in a water solution containing nickel salt and a phosphorus containing reducing agent usually a hypophosphite salt.

The electroless nickel phosphorous content affects the properties of the deposit significantly including hardness corrosion resistance and magnetism. They do not require rectifiers but they do require heating to approx 195 deg f. Electroless nickel plating is used for a wide variety of components in a range of industries including the automotive electronics and oil industries. It is the most common version of electroless nickel plating.

The aerospace industry uses it for similar reasons on valves engine shafts and. There is no need to pass an electric current through the chemical bath solution in order to initiate the plating process. Electroless plating kits caswell electroless kits are available for nickel cobalt tin boron nitride nickel and teflon nickel. The electroless nickel plating process en has several distinct advantages over the traditional electrolytic nickel plating process.

Car manufacturers use it to protect parts such as pistons fuel injectors and cylinders from wear and corrosion. Electroless nickel plating an overview electroless nickel plating is offered by advanced plating technologies in both type iv medium phosphorous 6 9 p and type v high phosphorous 10 14. The process of adding an electroless nickel plating to a metal surface is an autocatalytic chemical reduction. Hardness heat hardenability solderability electrical conductivity and abrasion wear and corrosion resistance.

Electroless nickel ptfe is produced via a precise autocatalytic process that is adjustable to various applications. The electroless nickel plating process is simpler than its counterpart electroplating. Electroless nickel plating en is a process that uses a chemical reaction to co deposit it s nickel phosphorus coating onto a desired substrate. The primary difference with the nickel plating process is that en does not require the application of an external electrical current to drive the deposition as does electrolytic nickel.
