Definitions

  • the subject of the present invention is a bead for coating by blowtorch projection.
  • a cord which allows to deposit on a substrate surface coatings of quasi alloy crystalline, that is to say an alloy having a specific crystallographic structure which translated by the presence of at least 30% by mass of an almost crystalline phase.
  • This orthorhombic phase O 1 is said to be approximate to the decagonal phase. It is so close to it that it is not possible to distinguish its X-ray diffraction pattern from that of the decagonal phase.
  • This phase is an approximate phase of the icosahedral phase.
  • phase C of cubic structure, very often observed in coexistence with the approximate or quasi-crystalline phases true.
  • This phase is isotype of a hexagonal phase, noted ⁇ AlMn, discovered in Al-Mn alloys containing 40% by weight of Mn (MA Taylor, Intermetallic phases in the Aluminum-Manganese Binary System, Acta Metallurgica 8 (1960) 256) .
  • the cubic phase, its substructures and the phases which derive from it, constitute a class of approximate phases of quasi-crystalline phases of neighboring compositions.
  • the alloys comprising these phases almost crystalline have specific properties that make them particularly interesting in the form of hardening surface coatings or protectors on various substrates.
  • these alloys have good hardness and friction properties as well good stability at higher temperatures at 300 ° C.
  • the present invention has precisely for object a cord usable to form by projection torch coatings of almost crystalline alloy, which avoids this prior operation for manufacturing the alloy and is suitable for making almost crystalline alloy coatings of any composition fixed in advance.
  • This embodiment of the cord the invention can be used in particular when the quantities of quasi-crystalline alloy to be projected are important and justify the preparation prior to an alloy powder.
  • torch projection generally leads to the production of an almost alloy coating lens not having exactly the same composition as the powder alloy, but we still keep the properties of a quasi-crystalline deposit.
  • the core comprises a mixture of powders capable of forming a quasi-crystalline alloy, for example a mixture of powders of the elements Al, X, B, C, M, N and I with X representing at least one element chosen from Cu and Co, M representing one or more elements of the group comprising Fe, Cr, Mn, Ni, Ru, Os, Mo, V Mg, Zn, Ga and Pd, N representing one or more elements of the group comprising W, Ti, Zr, Hf, Rh, Nb, Ta, Y, Si, Ge and the rare earths, and I representing one or more alloy impurities, in proportions such that the mixture of powders corresponds to the composition of formula: Al a X b (B, C) c M d N e I f in which X, M, N and I have the meaning given above, and a, b, c, d, e and f represent atomic percentages such that they satisfy the following relationships: 48 ⁇ a ⁇
  • This second embodiment of the cord of the invention is much more interesting because it makes it easy to make cords for the projection of almost crystalline alloys of compositions very varied. Indeed, just use in this case powders from the corresponding trade to the elements required to make the core of the cord and carefully dose these powders to obtain the desired alloy composition.
  • the projection cords described above can be prepared by conventional methods, in particular by cofiling two doughs, one constitutes the soul and the other is intended to form the outer sheath.
  • a process of this type is in particular described in document FR-A-1 443,142.
  • the core of the cord contains in addition a mineral binder which allows, during the operation projection to bind the powder particles between them until their complete fusion.
  • refractory oxide fibers such than alumina fibers.
  • This cord structure is very advantageous because we can choose appropriately the organic binder and the sheath material in view of obtaining a flexible cord, which allows continuously supply a torch projection.
  • the organic binder and the sheath organic material are chosen so that they can be easily removed in the blowtorch during the spraying operation, for example by combustion.
  • organic binder and organic material likely to be used, mention may be made of cellulose derivatives like methylcellulose, hydroxymethylcellulose, hydroxyethylmethylcellulose and carboxymethylcellulose, and polymers such as polyvinyl alcohol and polymethacrylic acid.
  • the core of the cord includes water, and / or an organic plasticizer, susceptible to be easily eliminated during the operation of projection, for example by evaporation and / or calcination.
  • plasticizer we may include glycerin, ethylene glycol and triethanolamine.
  • the proportion by weight of binder organic in the soul usually does not exceed 4%.
  • the present invention also has for object a method of depositing on a substrate a coating of almost crystalline alloy, which consists to use a flame spray gun oxy-gas or / and electric arc or plasma and to supply this pistol by means of a projection cord as described above, so as to project onto the substrate the almost crystalline alloy obtained by reaction in the flame of the components of the cord.
  • the projection cords of the invention are very advantageous in this process because they allow to introduce into the heart of the flame a thermal spraying device, the whole constituent elements of a quasi alloy crystal and ensure a residence time of these elements inside the flame sufficient to guarantee a complete response and training of an almost crystalline alloy.
  • the almost crystalline alloy thus produced is sprayed with feed gases from the projection device in the form of finely divided droplets on the substrate.
  • the cord core also contains fibers mineral, for example alumina fibers, these are also projected in the coating formed on the substrate.
  • the organic binder and the cord sheath are vaporized during the screening and they do not intervene nor in the training reactions of the alloy, nor in the coating.
  • This quasi-alloy projection mode lenses have several advantages over to the techniques of thermal projection of art that used powder torches. First of all, it frees you from the operation atomization of a quasi-crystalline powder of specific composition to replace it with a much simpler operation which consists to mix readily available common powders to form a paste. In addition, it authorizes the use of simpler projection devices and widely used. Finally, it offers the possibility compose the mixture of powders as desired and therefore to get any composition of desired alloy.
  • Quasi-crystalline alloy deposits obtained by this process have increased hardness and friction coefficients improved by compared to many deposits of current art. As well, these almost crystalline deposits are particularly indicated in any consistent tribological application to reinforce a metallic alloy surface iron-based, aluminum-based, copper-based or nickel-based.

  • the second embodiment of the cord of the invention is used, that is to say that the core of the cord is prepared, from the powders of the constituents taken separately having the characteristics given in the Table 1 below.

  • Aluminum powder finely divided was first coated by stearic acid to prevent its oxidation at room temperature.
  • the cords obtained also have a external diameter of 4.75mm and a thickness of 0.012mm sheath.
