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 types of this form of plating. The first one is the low-phosphorous treatment deposits a hardness of sixty using the Rockwell scale. It offers great protection from corrosion by alkaline solutions. Medium phosphorus process results in alloys that are of moderate levels of phosphorus. It offers a high deposit rate and a decorative component. It is the most used type. The high phosphorus treatment is ideal for industries as it is highly resistant to corrosion from acidic environments.
This process is done through an autocatalytic chemical reaction that ensures the continuation of the process since the product made still serves as a catalyst. The tool to be plate is immersed in an aqueous solution of dissolved nickel salt and a reducing agent such as sodium hypophosphite. This will cause a reaction that will deposit the element around the tool. The element deposited still catalyzes the reaction. There are no extra equipment or electrical power required.
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.
The manufacturing industry has been greatly improved through the use of this plating. It has met the abilities required for many materials in terms of strength, durability and superior resistance to corrosion. Its implementation has improved efficiency and performance of industrial lubricant components and provides high-quality products.
