Abstract
Procedeul de obtinere a structurilor autoportante ceramice compozite, conform inventiei, prevede folosirea ca umplutura permeabila cu care se înfiltreaza matricea ceramica policristalina, rezultata prin oxidarea de preferinta a Al, ca metal primar, zgura provenita de la topirea în conditii nitrurante sau sau oxidante uzuale a unor metale, alese între Al, Ti, Zn, Mg, Cu si aliajele acestora si care poate sa contina compusi de Mg, Si, Fe, Ni sau amestecuri ale acestora, maruntita la granulatia necesara, eventual prelucrata în conditii uzuale pentru îndepartarea partiala sau în cea mai mare parte a cantitatii de metal supus topirii antrenate în zgura si, respectiv, fasonata într-o preforma cu profilul si dimensiunea predeterminate.
