Abstract
Procedeul de obtinere a corpurilor cu structuri compuse cu matrice metalica, prevazute cu cel putin o cavitate, de forma si profil predeterminat, ce comunica sau nu cu exteriorul, conform inventiei, realizeaza infiltrarea spontana a matricei metalice constituite din aliaje uzuale de aluminiu, cu continut de Si, Fe, Mn, Cr, Zn, Ca, Mg si Sr sau de alt tip adecvat în masa/preforma de material ceramic de umplutura, alimentând totodata în sistemul de infiltrare spontana, fie în materialul de umplutura, fie în atmosfera de infiltrare, un precursor al intensificatorului de infiltrare sau intensificatorul de infiltrare ca atare, al carui tip este selectat în functie de natura atmosferei în care se desfasoara procesul de infiltrare spontana, care, trebuie condus pâna la consumarea totodata a matricei metalice topite prin infiltrarea mentionata si fasonarea prin replica inversa în masa/preforma de umplutura a cavitatii prestabilite.The process for obtaining bodies with metallic matrix structures, provided with at least one cavity, of the predetermined shape and profile, whether or not communicating with the exterior, according to the invention, results in the spontaneous infiltration of the metal matrix made of aluminum alloys, containing of Si, Fe, Mn, Cr, Zn, Ca, Mg and Sr or other suitable material in the preform / ceramic filler material, also feeding into the spontaneous infiltration system either in the filler material or in the infiltration atmosphere , a precursor of the infiltration enhancer or infiltration enhancer as such, the type of which is selected according to the nature of the atmosphere in which the spontaneous infiltration process takes place, which must be led to the consumption of the molten metal matrix by said infiltration and shaping by the inverse replica in the predetermined cavity filling mass / preform.
