Sobre IBD

Cette étude explore les propriétés mécaniques de l’alliage d’aluminium 7075 (Al7075) renforcé avec de la poudre de cuivre (0 à 2 % en poids), conçu pour des applications dans l’industrie automobile. Les matériaux composites ont été fabriqués à l’aide d’un moulage sous vide poussé, garantissant une distribution uniforme des particules de renforcement. Le comportement à l’usure a été évalué dans des conditions lubrifiées à l’aide d’un testeur d’usure multi-échantillons. L’incorporation de poudre de cuivre a considérablement amélioré les propriétés mécaniques clés, la résistance à la flexion passant de 329 MPa à 499 MPa, la résistance à la traction passant de 232 MPa à 396 MPa et la résistance aux chocs passant de 20 kJ/m² à 69 kJ/m².
