Lubrinip PTFE

Non-stick electroless nickel composite deposit

Homogeneous incorporation of PTFE into the matrix
General

Lubrinip PTFE is a composite deposit consisting of a nickel-phosphorus alloy matrix in which very fine particles of PTFE (Teflon) are incorporated, giving the surface non-stick and sliding properties. Thanks to the homogeneous incorporation of PTFE throughout the thickness of the deposit, these properties are constant and regenerative.

Lubrinip PTFE coating is particularly recommended when a non-stick, hydrophobic surface is required that reduces the coefficient of friction/friction. This reduces wear and tear on mechanical parts and the associated maintenance costs. Its hydrophobic nature provides cost-effective solutions to lubrication, friction, adhesion, wear and corrosion problems.

Our Lubrinip PTE treatment can be applied with excellent adhesion to all common metals and construction alloys, as well as light aluminum and magnesium alloys.

Lubrinip PTFE treatment is a chemically deposited nickel dispersion layer. This indicates that a uniformly distributed incorporation of tiny non-metallic particles (PTFE) is present in the nickel-phosphorus matrix. Offering the following benefits in particular:

  • 100% functionality until complete wear of the layer

  • Dry and self-lubricating lubrication of mechanical systems

  • Increase the strength and durability of parts

Depending on the temperature and duration of the treatment, a post-surgical heat treatment of the treated parts can modify certain aspects of the product.
deposit properties, such as; improving lʼadhesion, relaxing internal stresses and increasing hardness, toughness or ductility.

Application examples
  • Gearbox components

  • Industrial vacuum pump

  • Printing machine parts

  • Mold for plastic injection and thermoforming

  • Valve seats
  • Hydraulic elements
  • Slide bearings

  • Connections
