Title:
PREPARATION METHOD FOR CONCHA MARGARITIFERA-LIKE LAYERED HIGH-STRENGTH SUPER-TOUGH CERAMIC
Document Type and Number:
WIPO Patent Application WO/2021/258746
Kind Code:
A1
Abstract:
A preparation method for a concha margaritifera-like layered high-strength super-tough ceramic, comprising the following steps: coating the surface of a multi-sided hollow micro-porous structure of a foam ceramic matrix with a weak interface layer formed by toughening particles; pre-pressing the coated foam ceramic matrix to obtain a ceramic green body having a layered structure; pressing and sintering the pre-pressed foam ceramic to realize a fine combination of the bionic layered structure; and finally hot-pressing and sintering, so as to obtain the concha margaritifera-like layered ceramic, thereby significantly improving the toughness of the structural ceramic on the basis of the strength of the structural ceramic being not impaired.
