As experts in the process of nickel plating, the us staff are highly experienced and knowledgeable regarding the use of this innovative plating technique. There are many benefits to using nickel plating over other metal finishing techniques, many of which are outlined below.
1. Uniformity of Coating
The deposit formed by electroless nickel plating is based on a chemical reaction, causing the deposit to collect in equal thickness over all the part, regardless of its shape.
This completely uniform coating is a perfect solution for critical high-end engineering items including those used in the defence, healthcare, automotive and aerospace industries.
2. Ultimate Corrosion Resistance
Electroless nickel coatings are often used in functional applications because of the excellent corrosion resistance it provides. Nickel coatings are able to withstand the combination of abrasion and corrosive chemicals, even in the very corrosive conditions encountered in drilling and producing oil wells.
3. Wear Resistance
Electroless nickel has excellent levels of wear resistance. As a barrier layer, it is used on oil field valves, drive shafts, electrical tools and industrial machinery. The life of any metal exposed to harsh environments can be extended using this type of plating, therefore reducing the cost of repair and replacement parts. It basically extends the life of everything it coats! And with the appropriate heat treatment, electroless nickel can be hardened up to 950vhn, which makes it ideal for areas exposed to friction and wear.
4. Excellent Adhesion
A high level of adhesion can be achieved on a wide range of substrates, including steel, copper, and aluminium. The typical bond strengths reported for electroless nickel on copper and iron alloys range from 50 to 60,000 psi. The bond strength on light metals such as aluminium tends to be lower, somewhere in the range of 15 to 35,000 psi.
Heat treatment at a low temperature is commonly used to improve the adhesion of electroless nickel on all metals, especially on light metals such as aluminium or titanium. During this heat treatment, diffusion occurs between the atoms of the coating and the substrate.
The surface preparation and activation of the electroless nickel plating is one of the most important factors for producing excellent adhesion.
5. Cost Effectiveness
Specialist electroless nickel plating is much cheaper than you would imagine. us now have 7 dedicated nickel plating lines and can offer reasonable quotations based on drawings or photos sent to us.
As you can see from the points made above, electroless nickel plating has many huge benefits that make it the plating method of choice for many industries. Call us on our phone number, email us at email@example.com or visit the contact page on our website to make an enquiry.
