Popis:	A pressure-vacuum infiltration (T = 720 ºC, p = 15 MPa, t = 15 min) and gas-pressure infiltration (GPI) in an autoclave (T = 700ºC, p=4 MPa, t=5 min) were applied for infiltration of porous Al2O3 ceramics by cast aluminum alloy. Effect of the method of the infiltration on the microstructure and mechanical properties of ceramic-metal composites, was studied. Ceramic preforms were formed by method of copying the cellular structure of the polymer matrix. The results of the X-ray tomography proved very good infiltration of the pores by the metal for each method.
