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 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.
The pretreatment process is undertaken before plating is done so as to get rid of any substances that may hinder the proper formation of deposits. This is done so as to avoid poor plating of the tools. There are several chemicals used in the cleansing process after which water is used to clean them off in situations where they may cohere to the material.
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.
Its use in the automotive industry is used to protect vehicles from wear and corrosion. There should be compliance to the process types that are approved which requires that the process used is free from heavy metal stabilizers. It also uses the coating of hard discs.
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.
