EN coating is a process done to produce nickel phosphorous coating which can be use for the enhancement of corrosion, resistance to wear, and to increase the hardness of the surface even. Electroless nickel coating MI is used by many because it does not require an electric current unlike others.
The process is simple, it will be coated with a nickel but only with a thin layer as if you did not put something into it. With this, you do not have to use electric current just to complete the process anymore. The amount of advantage you get from this is great. Truly doing this is a great choice that you will make. However, the whole thing can be complex.
One, prepare the parts. Before doing the processing part, you need to prepare the parts already. You need to chemically pretreated it and afterward rinsed it out with water to remove those surface contaminants before the plating starts. To improve the condition of the surface, you want to do a mechanical finishing process.
Have the water purified. The problem you feel face about water is you have to do some purification into it first before using. You see, water is going to be filled with foreign matters which is naked to the eye. In order to remove those, the water has to go over purification. Just be prepared as the whole operation could take long.
Three, know what tank to use. Selecting tanks is a crucial part. The tank is responsible for holding the EN bath which means you can only use a tank made from polypropylene and stainless steel. If you compare the two, stainless is the one that will last longer. However, if you want to prevent plate out, polypropylene is the better choice.
Fourth, constant filtering is needed. The plating bath contains insoluble materials and that should not be present. In order to remove that filtering it is the only solution. The reason being, the substrate might roughen. Every time you turn it over, do the purification four to five times and that is per hour. When you do this, all the impurities will be gone.
Five, control the temperature. You have to monitor the temperature of the plating bath all throughout the whole process. That is because, when the temperature is too high, decomposition could speed up and if it is the opposite, the process will go beyond the accepted level which might prevent coating deposition from happening.
Test your solution every once in a while. It is given that sometimes the actions you will do is not perfect. Since you need to add the right amount of chemical, make sure that the solution will be tested always. Just add a little amount and only add when it is not the right amount. Just add until its balanced.
Seven, conduct some post treatment process. To prevent stain from happening apply some chromate to the area. For harmful conditions, baked the plating first before using it. Post treatment is a very important step that you have to do. If you do not do this there is a great chance that staining and harmful conditions will appear.
