Tribofilm Release Mechanism

  • Pioneers in Commercial Production of Inorganic Fullerenes

    NanoMaterials was the first company to succeed in commercially producing multi-layered, spherical and tubular nanostructures from inorganic materials.

    Tungsten Disulfide (WS₂) was the very first inorganic compound to be synthesized into multi-layered, spherical and tubular shapes. These novel particles have low chemical reactivity, low toxicity, and high metal bonding capacity. At the same time, the submicron (nano) particles have notably high pressure, impact and heat resistance.

    In tailored specific formulations, Inorganic Fullerene-like Tungsten Disulfide submicron particles are a great base for the creation of “super performing” lubricant additives, metalworking fluids, coatings, and polymer composites. The benefits may include, but not be limited to:

  • Excellent performance under extreme conditions
  • High impact resistance
  • Great energy efficiency
  • User-safe and environmentally friendly
  • Superior capacity to extend the life and improve the productivity of working mechanisms
  • 33-nanotube-115x2381

    32-nanospher-115x238

  • Inorganic Multi-Layered Fullerene-like Nanoparticles

    Our proprietary Tungsten Disulfide (WS₂) multi-layered nanospheres (aka Fullerenes) are a remarkable scientific and commercial achievement.

    NanoMaterials’ technology platform can produce extremely uniform and highly symmetrical spherical structures, composed of 20-100 concentric layers of inorganic compounds. The diameter of the primary particle ranges between 30 and 70 nm.

    IF-WS₂ multi-layered particles are extremely thermal- and pressure- resistant. In addition to that, IF-WS₂ outer layers exfoliate under extreme pressure, bonding with working surfaces. Nanoparticles fill in wear crevices and to create a super lubricating coating layer. Thus, the lubricant industry was a natural fit for NanoMaterials’ IF-WS₂ to be applied in.

    As “super lubrication agents”, IF-WS₂ submicron particles have proven their ability to reduce wear by up to 30% (depending on the base oil and working conditions). It has also been proven that the tribological efficiency of our IF-WS₂ particles increases with contact pressure.

  • Inorganic Multi-Layered Nanotubes

    NanoMaterials also produces unique WS₂ multi-layered nanotubes.

    Our WS₂ nano-tubes have low defect densities and are highly uniform, thus offering far better dispersibility than carbon nanotubes.

    The mechanical properties of our nanotubes include ultra-high-strength modulus and pressure resistance – both dynamic (‘shock’), and quasi-static.

    Our multi-layered nanotubes can be used in composites with various matrices (polymeric and non-polymeric). They will increase the wear resistance and improve the mechanical and thermal properties of the host matrices.

  • Active Protection Industrial Lubricants Based on IF-WS₂

    NanoMaterials’ Inorganic Fullerene-like Tungsten Disulfide (IF-WS₂) submicron particles are the new generation of dual-acting lubricating agents .

    IF-WS₂ Formulated lubricant additives and fully-formulated fluids offer the following benefits:

    • More efficient machinery operation (slower decrease of efficiency due to wear, less impact of heating)
    • Longer machinery life (continuous wear-damage reversal)
    • Better operation under stress conditions (high-load, high temperature)
    • Longer effective oil lubricant life (less heating, less friction, less need for erosive additives in formula)
    • Reduced energy consumption
    • Lower emissions
    • Lower service requirements (wider intervals)
    • Reduced operating noise (thanks to super lubricated operation)

  • Surface Reconditioning Mechanism

    IF-WS₂ nanoparticles define a new generation of dual-acting lubricants by combining advanced anti-friction (AF) and anti-wear (AW) properties. IF-WS₂ Formulated products have a unique ability to re-condition working surfaces over and over again.

    Under constant pressure and friction, the IF-WS₂ nanoparticles exfoliate and create a tribofilm layer on the surface. The exfoliated nanoparticle layers accumulate in wear crevices on the contacting surfaces and attach to the surface, creating a super-lubricating coating layer. This super-lubricating tribofilm layer stays attached to the contacting surface even if the lubricating oil is drained out.

    This unmatched surface-reconditioning (“wear & repair” & surface coating) mechanism makes IF-WS₂ Formulated industrial additives and lubricants a dual-acting AF/AW agent that extends the life and effective operation of both machinery and lubricant beyond the capacity of conventional lubricants.
