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 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 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.

This process is beneficial in many different ways. The metal that is plated has improved hardness due to the deposits. It does not need to use electric current and therefore saves on power. There are no complex methods that require being performed. It also produces a smooth and even coating. However, since a lot of chemicals are used and replenished, treatment of waste is costly.

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.
