Definitions

  • the present invention relates to a process for obtaining, by powder metallurgy, a material based on aluminum alloy, a solid lubricant and at least one ceramic intended for making parts subjected to friction. , such as for example the liners of internal combustion engines.
  • these alloys have the advantage, when they contain silicon in a hypereutective amount, of leading, during their manufacture by casting, to the formation of primary hard silicon crystals distributed in a softer aluminum matrix, which strengthens their resistance to wear and seizure.
  • This technique is also favorable for the incorporation into the alloy of solid lubricating products such as graphite, tin or even hardening agents such as silicon carbide for example.
  • the mechanical strength of such alloys can be increased by adding other addition elements such as copper, magnesium, etc.
  • the particle size does not exceed 7 wm.
  • This particular particle size can be obtained by any known means of spraying and / or grinding and sieving the ceramic used.
  • This ceramic may in particular be corundum, silicon carbide, zirconia and silica.
  • the amount of ceramic having given the best results is in the range of 5 to 25% by weight relative to the final material and preferably between 7 and 15%. Above 25%, there is a deterioration in the mechanical properties which can or could be remedied by carrying out a special sintering treatment under load in the presence of a liquid phase, but the price of the material thus produced is considerably increased. Below 5%, the ceramic does not have a sufficient effect.
  • the materials of the invention also contain a solid lubricant such as, for example, molybdenum disulfide, graphite, boron nitride.
  • a solid lubricant such as, for example, molybdenum disulfide, graphite, boron nitride.
  • the aluminum alloy with which the solid lubricant and the ceramic are mixed may be any alloy available in the form of a pre-alloyed or premixed powder.
  • the compression can be done either in a uniaxial press or in an isostatic press and the tablets obtained are either hot-spun in an extrusion press in the form of slabs or billets which are machined at the sides of the desired part or hot sintered from a blank with suitable dimensions.
  • the parts thus obtained are subjected to heat treatments such as dissolution, quenching and tempering.
  • seizure tests were carried out using an alternative PLINT tribometer based on the following principle: a metallic segment animated by an alternating rectilinear movement is rubbed on a horizontal and lubricated flat face of the piece. whether there is seizure or not.
  • the present invention finds its application in the production of parts subject to friction, such as engine liners in order to obtain an optimum compromise between the values of the coefficient of friction and of the resistance to seizing and wear.
