Composite electroless nickel deposit sliding and self-lubricating




The new sliding dispersion coat

The LUBRINIP BN coat consists of a particularly tough outside dead (chemically) solitary nickel layer, into which evenly and homogeny distributed BN-Gleitstoffe is stored. BN is a soft ceramic(s), which is used as high temperature fixed lubricant.

All usual construction metals (Konstruktionsstähle, highly alloyed steel, as well as cast irons, copper alloys, aluminium and titanium) can be improved with an excellent adhesion with LUBRINIP BN.

The surfaces wise outstanding tribologische characteristics treated with LUBRINIP BN up, how: the wear due to sliding the sliding partner, low coefficient of friction degrades, spares self-lubricating and unlubricated operation characteristics.

  • Regularity of the layer thickness particularly also on strongly formed surfaces (no irregularities).
  • Also inside cavities can be coated (pipes; Injection nozzles etc…)
  • Absolute control of the coating thickness and accordingly the final ratios of a piece of construction.
  • Resistant hardness after thermal treatment.
  • Outstanding resistance approximately not oxidizing chemical subjects and corrosion.

    Advantages of the Lubrinip BN 

  • Non-adhesive-end and self-lubricating
  • Low coefficient of friction
  • Resistant to wear and corrosion
  • Effectiveness at strong frictions and temperatures (start load and high friction speed)
  • Theoretical did not limit coating thickness (normally from 5 to 50 Micron)
  • Protruding execution and result reproducibility

    Some application possibilities

  • Pistons of explosion engines
  • Shears blade
  • Barillet de distribution de petites billes
  • Sliding rails of all kinds
  • Empreintes de moulage pour matériaux plastiques
  • Bloc de soudage, breakdown à more souder

    The practical ABC of the chemical nickel coatings LUBRINIP BN in questions - answers

  • Which are the surfaces, which can be coated ?

    All metals and normal structural steels as well as aluminium and its alloys except soft metals (Pb, Sn etc…)
  • Is it possible to treat hollow surfaces or internal portions ?

    Yes, because the penetrating ability of chemical nickel, which serves as basis for this procedure, is infinite. It is even possible to achieve a regular coating within a curved tube or a coil of pipe if the coating solution is in motion.
  • Does the thickness of the deposit is regular or have to be considered « point coatings » ?

    The thickness of the deposits of chemical nickel is identical and regular in all points of the surface of the part regardless of the complexity of his profile. The deposit coats the part which can be treated like a second skin the whole surface of a body enclosure.
  • Which is the thickness of the deposits of Lubrinip BN  ?

    The thickness of the coating is not limited actually (physical editions, which are to due to the tensions, delimitations of the procedure etc.), however corresponds the normal coatings between 5 and 100 lain to Micron, about which 80% are between 15 and 25 Micron.
  • Being possible to coat selectively by the portions is left blank, which may not be treated ?

    Yes. In practice a piece of construction as well as a technical design must be supplied which following details to contain must:
  • In green:: The portions which to be coated must .
  • In yellow: The portions which to be coated cannot have to be compellingly coated however.
  • In red: The portions which not to be coated to be allowed or which to be left blank have.
The einäugigen holes, which serve as centre holes for pins, must be left blank, if they are deep. Thread and boring systematically left blank if the required thickness 15 Micron to exceed. Generally each cover work causes extra costs for the order.
  • Is the adhesion of the coating good and reproducible ?

  • he adhesion of the chemical nickel coatings is outstanding on all metals to be treated can.
  • he good adhesion of the coating hangs to a large extent from the preparing range by that the parts before coating continuously.
  • The chemical composition and the micro Strukturale condition (trempé - revenu; nitruré; écroui laminé etc.) of the special steel and alloys must be indicated, in order to obtain the best results for the adhesion.
  • A thermal treatment after coating (~ °C) the adhesion on steel completely particularly completes 220 and on the aluminium alloys (~190°C)
