All You Should Know About The Electroless Nickel Coating MI

By Debra Howard


Nickel phosphorus is a covering that can be made from the electroless nickel (EN) plating process. It is a substance that is wear and tear resistant, develops corrosion and more so makes the surface hard. During the plating process, you will not require passing an electric current through the nickel surface. The entire process will occur as a result of chemical procedures. Below are some of the elements that you need to know about the electroless nickel coating MI.

It can offer a homogeneous coating. This can be attributed to the chemical process during its formation that makes the surface flexible in managing the thickness of that coating. The process can, however, be very complicated as total attention and accuracy.

Always prepare the elements thoroughly. All the parts used in the process should be chemically penetrated and rinsed thoroughly so as to eliminate all the pollutants and the contaminants. Pollutants and contaminants will interfere with the chemical process. You can improve the condition of the surface by using abrasive sandblasting and shot peening.

You need to ascertain the water is pure. The best water to use is the distilled one. Contaminated water can also contain an impurity agent that can compromise the reaction and the outcome. The water might look clean, but it is not. The germs are micro so you cannot see them with your naked eyes.

Choose wisely the tank that you will use for the process. It is acceptable for you to use polypropylene or the stainless steel tank for this process. The stainless tank might, however, elongate the process and furthermore you will require passivation for you to make them anodic. This makes polypropylene to be the most suitable one for this occasion since it prevents the plate out of that EN bank in the tank.

Remember constant filtering is paramount in that process. Constant filtering is essential as it will assist in eliminating the insoluble materials in the solution that consequently results in these substrate toughness. It is recommended that you use a filter whose porosity rate does not exceed five microns.

Keep the temperature in check at all times. You need to be extra keen in these levels of temperature set during the process. They need not be too high as that might quicken the decomposition process while on the other hand, the process might be sluggish if the temperatures are low.

You should also ensure that you do the continuous solution testing. You need to keep a good balance of these chemicals for your bath plating to be very effective. Monitor closely the quantities of the chemicals and ensure that they are in the right quantity. It is much possible to control at its initial stages rather than waiting to get a messy end at the end of the entire procedure.

Always do a post treatment process. For instance, the end results of this process could lead to staining which is a harmful condition. The staining can be reduced and eliminated by applying a post treatment chromate. That will ensure you get the best results. A post treatment checkup will also help you assess the results of your process and consider whether you have the desired results.
