Abstract

On présente un procédé de fabrication d'une pièce comprenant de l'aluminium, lequel comprend une étape de frittage sélectif par laser d'un mélange comprenant : une poudre de polymère pour former la matrice, une poudre d'un alliage d'aluminium quasi-cristallin, et une poudre d'un premier composé de renfort formant un angle de contact avec une goutte de polymère posée à sa surface inférieur à 90° et présentant une conductivité thermique à 20 °C inférieure à 100 W/m. K. Le mélange comprend en outre une poudre d’un deuxième composé de renfort, en polymère, ayant une température de fusion (ou de dégradation ) supérieure à la température de fusion du polymère de la matrice. La somme du poids de l'alliage et du poids des composés de renfort n'excède pas 80 % du poids total du mélange.A method of manufacturing a part comprising aluminum is presented, which comprises a step of selective laser sintering of a mixture comprising: a polymer powder to form the matrix, a powder of a quasi-aluminum alloy. -crystalline, and a powder of a first reinforcing compound forming a contact angle with a drop of polymer placed on its surface of less than 90 ° and having a thermal conductivity at 20 ° C of less than 100 W / m. K. The mixture further comprises a powder of a second polymer reinforcing compound having a melting (or degradation) temperature higher than the melting temperature of the polymer of the matrix. The sum of the weight of the alloy and the weight of the reinforcing compounds does not exceed 80% of the total weight of the mixture.
