Get To Know More About Application Of Electroless Nickel Coating MI

By Virginia Jackson


Electroless nickel plating is a method where a thin layer coat of nickel is placed on metal objects to provide effective protection from corrosive materials as well as tear resistance. It also serves as a corrosive tool. Thus electroplating can also be used to repair worn out parts for reclaim purposes. This technique uses an auto-catalytic technique to place a thick coating uniformly. Unlike electroplating, this method does not use electric current. It is important to learn about the process of Electroless nickel coating MI in order to reduce corrosion.

Low phosphorus, medium phosphorus, and high phosphorus are three main classifications of this form of metal plating. They are used to offer different advantageous properties depending on the use of the metal object. For instance, high phosphorus treatments will offer great resistance to acidic places such as oil drilling while the low phosphorus treatment prevents against corrosion from alkaline environments and offers a uniform thickness. Medium phosphorus, which is most frequently used provides brightness for cosmetic purposes as well as causes faster deposition of the element.

This process is autocatalytic plating that involves a chemical reaction that uses one of the reactants products as the catalyst. It issued dissolved nickel and a reducing agent most commonly sodium hypophosphite. When the catalytic metal is dipped into the solution deposits are created around the metal immersed and the reaction continues because the deposits also act as catalysts. There are stabilizers used to regulate pH levels.

Pretreatment is a process that is carried out on a material before it is plated. It involves the cleansing of the material with various chemicals in order to remove substances that may hinder effective playing process. Rising using water must be done two or three times to remove the chemicals used. Cleaning removes any forms of scaling while degreasing eliminates oily surfaces.

This form of plating has numerous applications especially in the field of engineering. It has been used over the years to reduce the corrosion of metal elements and improve general hardness. There are many metal tools that plate including kitchen objects, door knobs, bathroom fixtures, rotors and drive shafts among others.

Furthermore, it is applied in the automotive industry. However, there is a certain requirement that needs to be met. They types used should be free from heavy metal stabilizers. The hard disk drives are also protected from damaging the internal magnetic layer form any damage. It also provides an atomically smooth coating.

The preference of this form of playing is due to the many advantages that it has over other methods. It provides a coating that is slippery, bright, uniform and of the required thickness. It also does not need the use of electric current to be passed through the solution hence saves energy. However, chemicals have a short lifespan and require being continually replenished which increases costs used in their treatments.

The use of this process in many industries has improved the general functioning of the industrial products manufactured. It has allowed industries to venture into fields that were initially difficult due to corrosion and wearing of metals used. With this process, performance and durability of materials are improved.
