Unlike electroplating, electroless nickel coating does not use external electrical power to deposit a layer of this element on other metallic objects. Instead, it uses a chemical reaction that is auto-catalytic. It is done in the process of a reducing agent such as hydrated sodium hypophosphite or any other similar agent. It is a non-galvanic plating method that deposits a thick and uniform layer. This layer offers resistivity to corrosion and wears, chemical resistivity and lubricity. It is good to know more about Electroless nickel coating MI so as to provide durability for equipment.
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 requires the use of nickel salt and hypophosphite solution to serve as the bath for the base material. There are other chemicals that are used to regulate the pH level so as to allow the process to be stable. The catalyst used is the base material in the solution which causes the deposition of the element alloys in the product given.
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.
For many years, this process had been in use especially in engineering and other related fields. They are mostly used to increase the strength of equipment used and increase resistance to corrosion from acidic and alkaline compounds. They are used in the manufacturing of paper handling equipment, electrical or mechanical tools, optical surfaces for diamond turning and much more.
It is also used in the automotive industry to reduce wear of vehicle parts. Furthermore, it is used in the manufacturing of hard disks drives in order to provide a coating that protects the underlying magnetic layers from damage. It can also be used to salvage worn out parts because of the high hardness of the coating.
There are many advantages that come with using this process. It does not use electric power thus saving on energy costs. The coat achieved is also uniform and thick. It also offers bright or semi-bright finishing on the product making it a decorative element. However, the chemicals used need to be continually replenished and the cost of treating waste is high.
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.
