Things To Know Concerning Nickel Coatings

By Jennifer Kelly


Metallic plating refers to the process in which nickel is actually deposited on the metallic parts of any item. There many reasons why individual may actually prefer to use nickel. Some people actually electroplate with the purpose of decorating their items, to prevent corrosion, to inhibit wear and tear or even to construct up worn out parts. There are numerous advantages associated with nickel coatings.

Nickel can actually be used to prevent corrosion. Although lubricating these parts can also be used to prevent corrosion, this method is not dependable. This therefore calls for need to use metallic plating since it is the most dependable and less costly method. This method is useful in management of friction especially if the other parts are also plated using the same product.

This mechanical finishing involves abrasive blasting together with shot peening. The degree of purity of water used in this process also requires keen consideration. This is due to the fact that water with impurities when used in the EN bath actually gives out undesirable results. It is therefore extremely important to clean water from all possible metal ions, particulates as well as other foreign particles.

This item is actually essential in the formation of stainless steel. The major reason why most people prefer using this kind of material is basically to retain the aesthetic nature of the item. The application of this product in aerospace industry is not basically limited on the components of the engine only. The plating is also used in the protection of airframe assemblies like components of landing gear, systems of ramp rocking as well as actuator and flap components preventing them from wear.

It also necessary to control temperatures when coordinating this plating process. Higher temperature can lead to increase speed of decomposition of the solution in the bath. Too low temperatures on the other hand can lead to longer time in decomposition process or even causing the solution not to decompose at all. An effective EN plating basically demands continuous testing of the solution.

Examples of slots, grooves, blind hole, threads together with the inside part of any tubing can actually be electroplated using this material and their thickness actually remains unaltered. The thread fasteners are usually maintained tight when this process is used to plate them. This methods helps these threads to resist corrosion as well as eradicating galling of these threads which in turn increases their lifespan in service life.

This process involves removal of the excess hydrogen through post plating baking. The condition is can also be corrected through the use of post treatment chromate. The problem can also be solved using other various methods which includes cleaning the item mechanically instead of electro cleaning. Heated alkaline cleaners can also be used.

In order to achieve the desired results without much problems, part preparation is basically needed. This preparation is basically through treatment of the parts to be coated in order to remove any contaminants on the surface. Other mechanical processes such as abrasive blasting or even shot peening is extremely important so as to improve the condition of the surface substrate. Considering the purity of water is also important consideration. Impurities in water can actually lead to undesirable results.
