Uniqueness of Electroless Nickel plating Over Electrolytic

Nickel is amongst the most versatile metals universally employed for plating applications. With silver while color and attributes of being malleable and anti-corrosive, its coating can be applied on objects through a long-established electroplating process ( www.sun-glo.com/electroless-nickel ) with a backup of electric current while the second option is an electroless process where deposition takes place via autocatalytic reaction. Even though both procedures are used for metal finishing, however, electroless nickel plating has been proved to be more consistent to deal with any kind of substrates, how complex it is.

The uniqueness of electroless plating mechanism makes it widely applicable since it can be used for both conductive and non-conductive objects, which is a major limitation of traditional electrolytic nickel plating. When it comes to finishing of complex metal parts having unevenness, variable thicknesses as well as holes, managing them with the desired level of finishing with electrolytic plating is hard to achieve. Remarkably, with the appearance of electroless nickel finishing, now industries have been blessed to offer their clients with the electroless advantage of consistent thickness that, no way fears of the surface intricacy or current flow troubles. It can effectively reach even the hidden parts of surfaces, for example, bearing, and produce most standardize nickel coverage throughout the parts critical for its protection.

The Electroless Nickel Plating Process

Typically, the electroless nickel plating procedure entails the use of hypophosphite solution and nickel salt for washing the base material. It also needs the essential presence of some other compounds in the solution that helps control its pH levels while stabilizing the process. As dipped into the solution, the object acts similar to a catalyst and promotes deposition of nickel-phosphorous alloy over the substrate. Electroless nickel plating is often called as autocatalytic process since it plays the role of catalytic. The unique advantage of electroless plating can be brilliantly utilized by specialized plating companies that have skilled workforce to tailor the plating bath and overall chemistry to perfectly go with the nature of the metal object and get precise nickel plating with thickness and characters you’re in need of.

Electroless Nickel Plating-Key Benefits

Enhanced Corrosion Resistance

For applications where rust resistance is a key criterion, always think of electroless nickel to fetch the highest class of corrosion protective layer of the metals. Electroless nickel solution is, in essence, a liquid mix of nickel and phosphorous whereas phosphorous is the element that results in enhanced corrosion resistance. On the contrary, while requiring 99% pure nickel solution for plating, traditional electroplating needs cannot reach the level of the anti-corrosive property.

Uniform Coating Distribution

If you produce metal components featuring deep channels, buried surfaces, holes and other complex configurations, then the application of electroless nickel plating is your ideal choice. Opposed to traditional electrolytic process, the autocatalytic reaction of the nickel-phosphorous coating can stick to all complex substrates with better reach.

Control Coating Density

Depending on the amount of coating density your product needs, electroless nickel boasts greater flexibility to determine and control the density of the metal coating. Simply by changing the amount of phosphorous to be mixed, the desired thickness can be well achieved. The thumb rule is the lower the phosphorous mix, the higher the density of your coating.

Enhanced Surface Hardness

If you’re in need of extremely durable, robust, and protective product coating ( https://www.sun-glo.com/blog/ ), electroless nickel plating can produce your satisfying level of product layer. Apart from being rust resistive, electroless high class of hard-wearing surface property protective to abrasion, wear, and friction.
