Abstract

La présente invention se rapporte au domaine de la technologie du traitement de piston d'automobile. L'invention se rapporte à un matériau de piston de moteur et à son procédé de traitement. Elle surmonte l'inconvénient d'un piston classique selon lequel une gorge de cylindre est trop importante pour satisfaire l'exigence d'un moteur conforme à de nouvelles normes. La proportion de chacun de ses composants est la suivante : une quantité de silicium (Si) comprise entre 11 et 13 %, une quantité de cuivre (Cu) comprise entre 1 et 1,5 %, une quantité de magnésium (Mg) comprise entre 0,8 et 1,5 %, une quantité de nickel (Ni) comprise entre 0,8 et 1,5 %, une quantité de manganèse (Mn) comprise entre 0,3 et 0,8 %, une quantité de chrome (Cr) comprise entre 0,1 et 0,3 %, une quantité de titane (Ti) comprise entre 0,05 et 0,2 %, une quantité de carbone (C) comprise entre 0,1 et 0,3 %, un mélange de terres rares compris entre 0,1 et 0,3 %, une quantité de fer (Fe) inférieure à 0,7 %, une quantité de zinc (Zn) inférieure à 0,3 %, une quantité de zirconium (Zr-) inférieure à 0,05 %, une quantité de plomb (Pb) inférieure à 0,05 %, une quantité d'étain (Sn) inférieure à 0,05 %, une quantité de calcium (Ca) inférieure à 0,02 %, le reste étant de l'aluminium (Al) ; le matériau souhaité est obtenu par ajout d'éléments traces tels que le manganèse (Mn), le chrome (Cr), le titane (Ti), le carbone (C), de terres rares et analogues sur une base de l'alliage d'aluminium ZL109, et d'un traitement utilisant des procédés de mélange électromagnétique, de coulée et de traitement thermique.
