Abstract
Produsele ceramice compozite, autoportante, conform inventei, sunt formate dintr-un substrat din metalul initial precursor, ales între Si, Ti, Zr, Sn, Hf si de preferinta Al, din umplutura permeabila, performata, suprapusa pe acest substrat si din matricea ceramica policristalina dezvoltata prin reactie de oxidare a metalului initial mentionat în preforma de umplutura pe care o fixeaza si stratul metalic mentionat, cu care formeaza un ansamblu integral. procedeul de obtinere a produselor ceramice, mentionate, realizeaza oxidarea sistemului metal-initial-preforma de umplutura permeabila cuprinzând o sursa primara de metal initial în stare topita si un rezervor de metal ce comunica cu sursa primara, asigurând reumplerea sursei primare de metal initial pe masura consumarii acesteia prin oxidare astfel, încât, prin reumplerea sursei, se continua formarea produsului reactiei de oxidare pentru infiltrarea întregului volum al masei de umplutura, obtinerea structurii ceramice compozite, de forma si dimensiune predeterminata si mentinerea metalului în contact cu matricea policristalina sau umplutura ceramica, astfel încât dupa terminarea reactiei metalul nereactionat sa se solidifice în contact cu structura ceramica compozita mentionata si sa formeze substratul metalic component integral al acesteia.The self-supporting composite ceramic products according to the invention consist of a substrate of the precursor metal, chosen between Si, Ti, Zr, Sn, Hf and preferably Al, from the permeable filler, performed overlaid on this substrate and the ceramic matrix polycrystalline formed by the oxidation reaction of the parent metal mentioned in the filler preform which it fixes and the said metal layer, with which it forms an integral assembly. the process for obtaining the said ceramic products accomplishes the oxidation of the permeable metal-preform-preformed metal-containing preform system comprising a primary molten parent metal source and a metal reservoir communicating with the primary source, ensuring the refilling of the primary source of the initial metal as consuming it by oxidation such that, by refilling the source, the formation of the oxidation reaction product continues to infiltrate the entire volume of the filler mass, obtaining the composite ceramic structure, the predetermined shape and size, and maintaining the metal in contact with the polycrystalline matrix or ceramic filler, so that upon completion of the reaction the unreacted metal solidifies in contact with the said ceramic structure and forms the integral metal substrate thereof.
