Definitions

  • AFC nano-powder compound
  • the nano-powder compound according to the invention is applied on units and mechanisms of the engine during their normal working state without having to interrupt their use.
  • State of the art As it is known, metal surfaces observed on a microscope look like mountains with peaks and valleys.
  • Metal plated lubricants that allow the formation of a protective layer on contact elements are known and are based on the following soft metals: copper, tin, lead, zinc, silvers and others that favour the decrease of wear action and intensity affecting the contact surfaces.
  • the metal plated lubricants according to the phase index, are divided into homogeneous and heterogeneous.
  • Anti-friction and endurance characteristics of the film generally depend on: manufacturing conditions; composition of the lubricant structure; time passed after the insertion between contact surfaces; state of the contact surfaces.
  • a friction geo-alterating compound with few big mixed isomorphic iron (magnetite) after mechanical action on the mineral (shattering and grinding), those big particles are removed with the magnetic selection method.
  • the defect of the use of this compound consists of the possibility of causing an high abrasive wear; this may happen mainly during the initial period of adjustment between the contact metal surfaces after the insertion of the above mentioned solid covering lubricant.
  • the content of the solid components even though is reduced due to magnetic selection, still remains quite high in the filling substance, like the following mass %: Magnetite 8,2 -8,6 Flint 0,6 -1 ,0
  • Fig. 1 shows a block of the base mineral (serpentine) used for the production of the nanoparticles.
  • Fig. 2 shows schematically, the lubricant containing heavy metals generated by friction (1 -a) and (1 -b), the compound according to the invention consisting of nanoparticles (2-c, 2-d)
  • Fig. 3 shows schematically the lubricant, containing heavy metals generated by friction (1 -a), the protective layer generated by AFC along friction surfaces (gears) (3-e / 3-f).
  • the nano-powder particles whose size is few millions part of a millimetre, derive from serpentine mineral (Magnesium Oxide, Silicium Dioxide, Water) (Fig. 1 ).
  • the AFC compound is added to the lubricant oil that usually is old oil containing heavy metals as the wear result (Fig. 2). Due to the AFC effects, the metal particles released in the lubricant oil due to the worn out engine components and mechanisms, fill up grooves and empty spaces between the surface micro- mountains; AFC actually works as metal catalyzer and quickly causes the conditions to form a thin protective layer (modified layer) on gears' surfaces.
  • This layer is oriented along the electric field and it consists of an anti-friction covering thin layer that is permanent and stable for long time (Fig. 3).
  • This protective layer is formed in every part of the engine where metal surfaces with iron (Fe) content rub off.
  • AFC compound enters deeply in metals grooves and empty spaces improving crystalline grid structure; metal surfaces become stronger, endurance to abrasion and wear increases and the anticorrosive characteristics improve as well.
  • AFC compound, involved in thermodynamic processes occurring on rubbing metal surfaces gives rise to the formation of a thicker modified layer as the involved metal parts are more deteriorated. The layer formation become progressively stable to reach the optimal value along all the metal surfaces affected by friction.
  • the use of the anti-friction and anti-wear compound is able to restore and improve the performances of :
  • the modified anti-friction layer over the treated metal surfaces allows from 10 to 20 % reduction of electricity and fuel consumption.
  • Vibration and noise reduction allows an absolutely new vibro-acoustic effect with a consequent increase of machinery's competitiveness.
  • the modified protective anti-friction layer is definitely a permanent layer, thus frequent oil substitutions and the use of high quality oil can be avoided.
  • the proposed technology is able to restore the deteriorated mechanisms, increase significantly their functioning duration, recover the original capacity and efficiency, with a cheaper and technologically easier solution than traditional maintenance techniques.
  • the anti-friction anti-wear compound according to the invention comprises a native pulverized mineral, whose particles are not bigger than 10 micron, consisting of: Serpentine (Lizardite and Chrysolite) 78-85%, Chlorite 2-3%, Magnetite 1 -2%, Amachynite 1 -2%, Amphibole 1 ,5-2%, Calcite 0,5-1 %, amorphous phase of X-ray 9-12%, the pulverised mineral can be added as such where required or can be dispersed in a lubricant and thereafter poured in the engine.
  • Serpentine Lizardite and Chrysolite
  • AFC is used in the field of machine construction, particularly inside lubricant products for parts, made up of alloys with or without iron content, affected by friction; it can be used in addition to the lubricant oil of internal combustion engine, for mechanisms, devices and to diesel fuel; furthermore, it can be used inside solid lubricant material, in cars, in railway transport, in boats and ships, in devices of mineral industries and pumping systems of gas and petroleum industries.
  • AFC powder composition depends (Table 2) on the working time of the planetary mill, and the target is to reach particles size comparale to the parameters of a crystalline lattice. Afterwards, the disintegration process gives rise to the reconstruction (modification of the crystalline lattice) with the consequent change of the substance's thermodynamic characteristics and reaction capacity.
  • Amorphous phase of X-ray substance (9 -12%) indicates that AFC substance contains some nano-particles with a developed surface characterized by high catalyzing and reaction quality: these particles give rise to a quicker and more effective formation of the defensive film.
  • nano-particles smaller than 100 nm stay afloat in the liquid substance (lubricant material) due to the Brownian motion: this allows a more effective use of the AFC substance with the consequent concentration decrease of the inserted powder (a small portion sediments due to the gravity force or settles in the depuration filters).
  • the selective transfer induced by the AFC is a special type of rubbing that consists in the spontaneous formation of the fine stainless film over the contact region (called defensive film).
  • defensive film With the introduction of the anti-wear and antifriction compound (AFC) in the lubricant, the anti-wear effect performed by means of the selective transfer turns out as follows: a defensive film formed by lubricant added materials settles on the friction surfaces during the working process. This substance cannot be removed from the friction region: it develops the preserving property. The defensive film rules out the interaction between rough surfaces, and the electric charge of the wear generated particles brings back themselves on the surfaces' contact region.
  • the film thickness is 1 -4 micron, which corresponds to the roughness for most of the mechanical construction particularities (or is even thicker).
  • the defensive film formation during the friction process occurs due to its generating mechanism caused by the intensity of the energy and matter exchange between the friction point and the outer environment and also for the collective behaviour of the ions of the activated material.
  • the defensive film properties formed during the friction process are different from the starting material ones.
  • a supplementary polymeric film consisting of metal- organic compounds is generated (called surfing-film), thus a supplementary antifriction layer is formed.
  • surfing-films are formed due to the interaction between the lubricant active molecules and the defensive film itself.
