ENSlick Nickel-Teflon Coating
ENGINEERING PROPERTIES OF NICKEL…LUBRICITY OF TEFLON®…REPEATABLE COATING OF UNIFORM THICKNESS
Electrolurgy’s ENSlick Electroless nickel-Teflon® is a nickel-phosphorous-polytetrafluoroethylene (PTFE) co-deposit on metal substrates. Our proprietary process yields a surface with the engineering properties of nickel and the additional lubricity of Teflon®. As with standard electroless nickel, the deposit occurs through a non-electrolytic chemical reaction that creates a consistent, repeatable coating of uniform thickness. This makes it possible to effectively coat parts with sharp edges, deep recesses, seams, threads, and complex geometries. In some cases, the use of our ENSlick nickel-Teflon® provides lubricity sufficient to eliminate the use of other lubricants.
Electrolurgy’s ENSlick coating can withstand temperatures up to 475 Degrees F. The appearance of the plated finish is usually dull silver-gray, and can be used as a non-reflective coating for military applications. ENSlick can be applied over a variety of base materials including stainless steel, aluminum, copper, brass and others. Originally developed in the 1990’s, Electrolurgy has been optimizing the coating qaulities and application methods for over three decades.

ELECTROLURGY’S ENSLICK NICKEL-TEFLON PLATING CAPABILITIES:
- Plating thicknesses from 0.0001 to 0.0050 inches
- Rack and Barrel Plating Available
- Precision masking for selective surface plating
- Salt spray corrosion testing per ASTM B 117
- Post-plate hydrogen embrittlement relief
- Hardnesses up to 70Rc (high phosphorous with post-plate bake)
- XRF thickness analysis
- MIL-F-14072 (M265)
- AMS 2405 MIL-STD-171 (1.4.3)

- The ENSlick plating process is aqueous and takes place at a temperature of 190 F.
- While the process applies a uniform coating on all geometries, adequate solution flow is required. Blind holes or obstructed areas may receive less coating.
- Stainless steels and non-ferrous substrates may require post-plate thermal treatment to improve deposit adhesion.
- High-phosphorous electroless nickel will often discolor when given post-plate thermal treatment for maximum surface hardness.
COMMON APPLICATIONS OF ENSLICK COATINGS:
- Aerospace Components: For wear resistance, corrosion protection, chemical resistivity and lubricity on valves, pistons, engine shafts, engine mounts, compressor blades and other flight-critical components.
- Electrical Equipment: Due to solderability and conductivity properties.
- Packaging & Handling Machinery: Due to wear resistance, cleanliness and attractive finish.
- Chemical Manufacturing and Transport Equipment: Due to chemical resistance.
- Molds & Dies: Corrosion protection minimizes erosion and abrasion. Low coefficient of friction improves release.
- Food Service Equipment: For superior corrosion and wear resistance, attractive finish and cleanliness.
- Plastics Manufacturing Equipment: For durability and release properties on injection molds and extrusion dies.
- Oil & Gas Components: For corrosion protection in harsh undersea and underground environments for parts such as valves, pumps, pipe fittings and others.
- Printing Industry Equipment: For abrasion resistance on conveyance and chemical resistance on printer cylinders.
- Automotive Components: For wear protection and corrosion resistance on pistons, cylinders, gears, fuel injectors, ball studs, hose couplings, heat sinks and others.
- Salvage: For restoration of parts to their original dimensions or to bring mis-machined parts into required tolerance.
