Alternatives to electroless nickel? - Finishing
Electroless nickel plating is generally much more expensive than electrolytic plating, but offers better corrosion resistance, greater hardness, and far more uniform thickness of deposit. It is probably more appropriate for your application. Nickel boron plating offers low resistance and is best for electronic applications. However, it is more expensive than nickel phosphorous, and improvements have been made in nickel phosphorous plating, offering deposits of low, mid, or high …
Electroless Nickel Deposition: An Alternative for …
Electroless nickel deposition was explored for the first time as a metallization alternative for CVD transferred single-layer graphene substrates. The obtained average nickel contact resistance of 43 ± 5 kΩ·μm significantly improved via annealing at 400 °C giving a 50% reduction in contact resistance to 21 ± 2 kΩ·μm. Surface analysis indicated that variable metal adhesion onto the graphene samples is a …

Alternative to Electroless Nickel Plating
Chrome plating would provide equal or better abrasion resistance, but it is not as corrosion resistant as electroless nickel. It may be possible to heat treat, or even cryogenically treat the surface for greater abrasion resistance. Salt bath nitriding might be doable and would improve both the corrosion resistance and wear resistance compared to plain steel. PVD processes are probably not …
NIPHOS® 966 Nickel-Phosphorus Electrolyte as …
Alternative to electroless nickel With NIPHOS® nickel-phosphorus alloy layers with high phosphorus content can be plated electrolytically in barrel-, rack- or reel-to-reel lines. Compared to electroless nickel layers containing a high phosphorus content, the electrolytic nickel-phosphorus layers are amorphous, diamagnetic and abrasion and corrosion resistant.

Hard chrome alternatives and electroless plating for engineered coatings from U.S. Chrome including MIL-C-26074, ASTM B733, AMS 2404, nicom and tricom coatings
Properties and applications of electroless nickel
Alternatives are sodium borohydride and dimethylamine borane but they are used much less frequently. It is estimated that sodium hypophosphite is used in more then 99% of all electroless nickel plating1 and this publication refers only to the use of this reducing agent. It is not the intention of this publication to provide details of the electroless nickel process but rather to review the ...
Electroless nickel plating - Wikipedia
16.04.2006 · Electroless nickel plating (or EN plating) is a stone process that deposits an even layer of nickel-phosphorus or nickel-boron alloy on the surface of a solid substrate, like metal or plastic.The process involves dipping the substrate in a water solution containing nickel salt and a suitable reducing agent.. Unlike electroplating, the process does not require passing an electric current ...
The Electroless Nickel Plating Procedure - …
Electroless nickel plating, also called stone or autocatalytic nickel plating, serves as a viable alternative to traditional electro nickel plating. Unlike electro nickel plating, electroless nickel (EN) plating doesn’t depend on an electric current to apply nickel coating. Instead, a stone reaction known as catalytic reduction deposits a layer of
Exploring Safer Alternatives to Chrome Plating - …
Hard chrome alternatives featuring nickel include: Nickel Silicon Carbid: ... Electroless Nickel: EN can provide a good barrier coating that enhances corrosion resistance. Because electroless nickel does not require an electrical current for deposition, the process results in a more uniform coating application than hard chrome plating. Applications where EN can serve as an acceptable ...
Chapter The Fundamental Aspects Of Electroless Nickel Plating
The fundamental Aspects of Electroless Nickel Plating 3 In 1844, Wurtz (2) observed that nickel cations were reduced by hypo- phosphite anions. However, Wurtz only obtained a black powder. The first bright metallic deposits of nickel-phosphorus alloys were obtained in 191 1 by Breteau
Difference between Nickel plating and Electroless …
Electroless nickel generally offers significantly greater corrosion resistance at significantly greater cost. There are many responses on this thread which attempt to answer your question in terms of corrosion resistance, consistency of thickness, hardness, magnetic effects, temperature resistance, speed of deposition, etc. If you give us the specific application & situation, I think people ...
PCB Process: ENAG - Electroless Nickel …
Electroless Nickel / Autocatalytic Gold (ENAG) ENAG is a high-performing final finish for wire bondable deposits, and an excellent alternative to immersion chemistry, or ENEPIG. It deposits 120-240 μins of nickel, 8-40 μins of electroless gold. Read “Neutral Auto-Catalytic Electroless Gold Plating Process” in the Uyemura library.
