Designed by KC Jones to withstand the most extreme wear, friction and abrasive environments, Miccrolloy Nickel Boron outperforms other chrome replacements. Coated in an autocatalytic process, Miccrolloy Nickel Boron provides multiple advantages over electroplating, such as high velocity oxygen-fuel (HVOF), thermal spray and physical vapor deposition (PVD).

Why Not Chrome?

Corrosion protection solutions have historically contained toxins. In recent years, the EU’s End of Live Vehicle (ELV) directive and its Restriction of Hazardous Substance (RoHS) directive banned the use of hexavalent chromium. These and other measures have led manufacturers to explore alternative materials.

Miccrolloy Nickel Boron Eliminates the Need for Hard Chrome:

  • Outperforms hard chrome and nickel-phosphorous (hardness/wear resistance)
  • Withstands high temperatures (melting point of 1080°C)
  • Provides greater abrasion and wear resistance
  • Increases ductility (due to unique columnar structure)
  • Has high hardness (Rockwell 70 C +)
  • Low coefficient of friction (rivals EN – Teflon™)
  • No hydrogen embrittlement (per ASTM 519)
  • Heat dissipation properties
  • Technology is well proven (conforms to ASTM B607 and AMS2433C)

How Aerospace, Automotive and Defense Apply Nickel Boron

Since the introduction of nickel boron, the world’s leading aerospace, automotive, and defense units have entrusted KC Jones Plating with their high-volume orders. Miccrolloy Nickel Boron has a wide range of applications and has been rapidly embraced by the aerospace and automotive industries because it is harder than hard chrome, with higher corrosion protection. Nickel boron is fast becoming the most popular alternative to hard chrome plating.

KC Jones Plating spearheads worldwide research and development of nickel boron coatings. It aims to increase the performance of nickel boron, which is critical to many of today’s industries. KC Jones also has the capacity for accelerated application development. Parts plated with KC Jones’ Miccrolloy nickel boron have been installed by major OEM’s, including Airbus, Chrysler, General Motors, Space-X, and WMD Guns.

Is Miccrolloy Nickel Boron Affordable?

Many hard chrome replacements are expensive. At times, they still contain toxic powders. In contrast, Miccrolloy Nickel Boron is affordable and toxin free.

KC Jones Plating has advanced on standard nickel boron formulations. Its proprietary Miccrolloy Nickel Boron has all the protective qualities of hard chromium and therefore is accepted as a hard chrome replacement. Lastly, it is one hundred percent, environmentally friendly.

Primary Features of Nickel Boron

  • 4-5 wt.% boron and 95-96 wt.% nickel
  • Coating uniformity (eliminates post-plate grinding and burnishing)
  • Naturally lubricious (due to unique columnar structure)
  • Applicable to
    • Carbon steels and stainless steels
    • Aluminum and aluminum alloys
    • Titanium
    • Inconel substrates
    • Ceramics
  • Uniform coating thickness up to .005″ (on most complex geometries)
  • Plated hardness: 650- 750 HV100
  • Heat treated hardness: 1200 – 1300 HV100

Engineered to Perform

For decades, electroless nickel-phosphorous (EN-P) was the standard nickel-based coating used by the majority of manufacturers. It was popular primarily due to corrosion, wear and abrasion-resistance properties. It was also liked for its hardness. Still it was limited because it did not have the low coefficient of friction of hard chromium.

Boron alloys cause a change in structure when they are added to electroless nickel. They improve sliding friction characteristics and lead to lower heat levels in-application. In fact, nickel boron coatings have an ultra low co-efficient of friction, that rivals Teflon™. This is important to high wearing and rolling applications. The world’s leading manufacturers now consider nickel boron to be the premium coating of choice for high friction and wear applications.

It is important to understand that KC Jones Nickel Boron (NiB), is not the same as commercially sold electroless nickel phosphorous with boron-nitride (BN). Nickel boron and nickel phosphorus coatings have different deposit structures. Nickel boron is a true alloy and it does not require particles for the powerful properties it possesses. Electroless nickel-phosphorus deposits contain co-deposited particles of self-lubricating hexagonal boron nitride. Nickel-phosphorous with boron nitride does have benefits in certain applications however it is not the same coating as nickel boron.

The Unique Columnar Structure of Electroless Nickel Boron

Nickel Boron has a columnar morphology due to the growth mechanism of the deposit. The columnar grain growth of the Ni-B deposits formed the surface of the coating a nodular (semi-hemispherical) structure. This surface texture can be described as cauliflower-like similer to an orange peel. This type of surface retains lubricants under conditions of adhesive wear. With the addition of lubrication, the spaces between each of the nodules act as localized reservoirs. This structure gives the coating its natural lubricating properties. The nodular structure reduces surface contact providing a low-friction surface and increased wear resistance.

Compare Nickel Boron to Similar Coatings

    • Nickel Boron is electroplated and delivers an even coating on every surface of parts, including recessive areas, blind holes and sharp edges.
    • Hard Chromium is electroplated and is a line-of-sight coating. This means high current-density areas get more plating than low current-density areas.
    • Electroless Nickel Phosphorous deposits are completely uniform just like electroless nickel boron. Still, when nickel boron is heat treated, it is harder than both electroless nickel-phosphorous and hard chromium. Click for full comparison
Nickel boron’s uniform coating results in reduced expenses because post-plating work like grinding polishing and machining are not necessary. KC Jones nickel boron conforms to material standards ASTM B607 and AMS2433C.

The Nickel Boron Story

Nickel boron was used in the 1960’s in Europe and the USA independently, by BASF and DuPont. It was used more commonly in Europe under the trade name, Nibodur. Initially, there were issues with nickel boron development that made it an inhibitive process. Most plating facilities were unable to offer this process because it was difficult to control. Today, KC Jones Plating is the only finishing company that continues to invest in development of nickel boron coatings. It is also the only facility in the world that offers a stable, consistent nickel boron plating process. KC Jones nickel boron does not contain lead, which is banned by the RoHS and ELV directive.

Latest developments in KC Jones nickel boron chemistry include:

  • Black Nickel Boron
  • Nickel boron with proprietary, non-reflective blackening treatment (utilized in military and defense applications)
  • Electroless Nickel Boron – Boron Nitride Composite
    • Increases hardness and lubricity through hexagonal Boron Nitride particles (at 10% by volume)

Nickel boron is a highly unique coating that outperforms hard chrome and electroless nickel-phosphorous in hardness and wear resistance. It is a lesser-known alternative to nickel phosphorous that provides longer machine runtimes, fewer breakdowns and improved part performance, since it is harder and more wear resistant. Nickel boron withstands higher temperatures and is more abrasion resistant.

For many years, aluminum and aluminum alloys were preferred over steel in applications where structural weight was an important economic factor. Still, it was low in hardness and had limited wear and abrasion resistance, which posed a significant problem. To resolve this, manufacturers would cover the aluminum and aluminum alloys they used with nickel boron, which provided both the hardness and wear resistance they needed.
