Get To Know More About Application Of Electroless Nickel Coating MI

By Virginia Jackson


This is one of the most common methods of electroless plating. It does not require passing an electric current through the solution given to create a deposit. It, however, uses a chemical technique referred to as auto-catalytic chemical reactions. This reaction means that the solution is catalyzed by one its products. This process produces a hardness factor, increase natural lubricity and offers resistivity to abrasion, corrosion and wear. It is, therefore, suitable to apply Electroless nickel coating MI process if you require providing a protective covering for metal tools and equipment without the use of external electricity.

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.

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.

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.

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.

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 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.
