Title (EN) MOTOR CYLINDER SLEEVES BASED ON ALUMINUM ALLOYS AND CALIBRATED SILICON GRAINS AND METHODS FOR OBTAINING THEM
(FR) CHEMISES DE MOTEURS A BASE D"ALLIAGES D"ALUMINIUM ET DE GRAINS DE SILICIUM CALIBRES ET LEURS PROCEDES D"OBTENTION
Abstract:
(EN) The present invention relates to sleeves for internal combustion engines based on aluminum-silicon alloys and silicon grains and to the methods for producing said sleeves. It is characterized in that said grains are carefully calibrated and dispersed in the alloy matrix. The sleeves may also contain at least one intermetal compound such as Ni3Sn, for example. Those sleeves are obtained by spinning or sintering of a mixture of powders. The invention finds application particularly in the motor vehicle industry and to all fields where sleeve-piston assemblies of good compatibility and based on aluminum alloys are desired.
(FR) La présente invention est relative à des chemises de moteurs à explosion ou à combustion interne à base d"alliages d"aluminium-silicium et de grains de silicium et leurs procédés d"obtention. Elle est caractérisée en ce que ces grains sont soigneusement calibrés et dispersés dans la matrice d"alliage. Ces chemises peuvent également contenir au moins un composé intermétallique tel que le Ni3Sn par exemple. Ces chemises sont obtenues par filage ou frittage d"un mélange de poudres. L"invention trouve son application notamment dans l"industrie de l"automobile et dans tout genre d"industrie où on cherche à disposer d"ensembles chemise-piston de bonne compatibilité à partir d"alliages d"aluminium.
