Electroless Nickel Phosphorus – Boron Nitride is a self-lubricating, composite coating that has hexagonal boron nitride particles co-deposited in its electroless nickel layer. Electroless nickel-boron nitride is produced via a precise autocatalytic process that is adjustable to various applications.

EN-boron nitride (EN-BN) is a hard, lubricious nickel coating that is ideal for sliding and high wear applications. It is often used on mold dies, medical components, and automotive components.

When nickel-PTFE cannot be used such as in high temperature and high load wear applications, EN-boron nitride is typically employed. PTFE is too soft in these instances and fails to withstand the environment.

Boron Nitride Particles Co-Deposited in Electroless Nickel Add Longevity

New particles of boron nitride are continually exposed as EN-boron nitride coatings wear down. This ensures lubricity and longevity.

  • Extreme self-lubrication (due to Boron Nitride)
  • Superior wear, corrosion and friction resistance
  • Dry lubrication
  • Low coefficient of friction (vital for sliding, moving & friction-wear applications)
  • Enhanced release (for molding operations)
  • Uniform coating and deposit thickness(even on complex geometries)
  • Ideal for delicate instruments and matte surfaces
  • Hardness:
    • 500 – 550 Knoop (plated)
    • 800 – 850 Knoop (heat treated)
  • Typical coating thickness of .0001″ – .0005″ thick
  • End-Of-Life Vehicle (ELV) Regulations and Restriction of Certain Hazardous Substances (RoHS) compliant
  • Ideal in high loading, higher temperature applications
  • Percentage of boron nitride can be adjusted to suit various applications
  • Boron nitride can be co-deposited in a low, medium, or high phosphorus electroless nickel processes
  • Boron nitride composition is typically 4-6% by volume

Please Note: Electroless Nickel-Boron Nitride is often confused with Electroless Nickel Boron. However it is not the same coating. Read more information on Electroless Nickel Boron.
