ELECTROLESS
NICKEL
Electroless Nickel PTFE (Teflon®)is an advanced, self-lubricating, composite coating that has PTFE particles co-deposited in the electroless nickel layer. Electroless nickel-PTFE is produced via a precise autocatalytic process that is adjustable to various applications.
Electronic, medical, automotive, aerospace, and defense industries all use electroless nickel-PTFE when components require more lubricity than traditional plating surfaces. They call for hard, uniform, self-lubricating coatings like electroless nickel-PTFE (EN-PTFE).
EN-PTFE is hard, and ideal for sliding and wear applications. It is also dry lubricating, highly lubricious, non-wetting, and has excellent wear and corrosion resistance. EN-PTFE is a low friction wear plating. It is ideal in applications where conventional lubricants cannot be used, such as injection molds, stamped washers and non-galling threaded parts. It is also now used as a more environmentally friendly alternative to cadmium-plated connectors.
Teflon Particles Co-Deposited in Electroless Nickel Increase Lubricity
- Extreme self-lubrication (due to PTFE)
- Superior wear, corrosion and friction resistance
- Dry lubrication
- Low coefficient of friction (vital for sliding, moving & friction-wear applications)
- Enhanced release, non-stick surface (for molding operations)
- Uniform coating and deposit thickness (even on complex geometries)
- Non-wetting surface repels water, oil, and other potential contaminants (due to PTFE)
- Hardness:
- 250 – 300 HK100 (as plated)
- 375 – 425 HK100 (heat treated, 350°C/2 hrs)
- Phosphorus Composition: 7-10% by weight
- PTFE (Teflon®) Composition: 4-9% by weight (13%-27% by vol.)
- Typical coating thickness of .0001″ – .0005″ thick
- Coefficient of Friction: Less than 0.10
- End-Of-Life Vehicle (ELV) Regulations and Restriction of Certain Hazardous Substances (RoHS) compliant
- Conforms to SAE 2454 specifications
- Ideal in low loading and low temperature applications
- Repels water, oil, and other potential contaminants (due to PTFE)
EN-PTFE can be further enhanced, by also coating opposing surfaces with EN-PTFE.
