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.
There are three main categories of this plating method namely low phosphorus, medium phosphorus, and high phosphorus each having their own advantages depending on the purpose it is required to perform. The low phosphorus treatment provides high resistivity to alkaline environments and a certain degree of hardness while medium phosphorus causes deposits to be formed at a faster rate. It is the most common type applied. The high phosphorus provides high resistance to corrosion from elements that are acidic in nature.
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.
Before this process is carried out, the tool to be plated must be thoroughly cleaned using different chemicals. This is done in a process called the pretreatment process. If it is not done, the plating process may be ineffective and result in poor plating. After pretreatment, the material is rinsed using water which removes the chemicals used in case they have adhered to the surface.
This process has many applications and it is mostly used in engineering to coat metal elements used so as to increase resistance to wear and tear as well as to prevent corrosion. The areas where this process is applied include the making of oilfield valves, kitchen utensils, drive shafts, electrical tools and office equipment.
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.
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.
Generally, this process is important as it results in improved mechanical and electrical properties and the cosmetic improvement of the tool to be plated. It is reliable and more preferred to electroplating. It improves the quality and gives superior lubrication and wear resistance.
