Electroless Nickel Plating

Electroless nickel plating is used for a wide variety of components in a range of industries including the automotive electronics and oil industries.

Electroless nickel plating. 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 electroless nickel phosphorous content affects the properties of the deposit significantly including hardness corrosion resistance and magnetism. It is the most common version of electroless nickel plating. First developed in the 1940s electroless nickel en plating is used heavily by automotive and aviation for corrosion and wear resistance.

Car manufacturers use it to protect parts such as pistons fuel injectors and cylinders from wear and corrosion. The electroless nickel plating process is simpler than its counterpart electroplating. This means that instead of using an outside source of electricity like in the similar electroplating process the electroless nickel plating process uses a chemical bath to deposit a nickel phosphorous layer onto the metallic surface. The process of adding an electroless nickel plating to a metal surface is an autocatalytic chemical reduction.

Electroless nickel ptfe is produced via a precise autocatalytic process that is adjustable to various applications. Comparatively this solution differs from other electroplating processes because it does not require an electricity source to coat the part. Electroless plating kits caswell electroless kits are available for nickel cobalt tin boron nitride nickel and teflon nickel. They do not require rectifiers but they do require heating to approx 195 deg f.

There is no need to pass an electric current through the chemical bath solution in order to initiate the plating process. It is a coating with multi functional properties. 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. Electroless nickel plating is a form of alloy treatment designed to increase resistance and hardness in a metal or plastic.

Hardness heat hardenability solderability electrical conductivity and abrasion wear and corrosion resistance. 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 electroless nickel plating process en has several distinct advantages over the traditional electrolytic nickel plating process. The aerospace industry uses it for similar reasons on valves engine shafts and.
