Patent CA-2524784-A1 (CA)
Inventor: MEKKY WALEED
IPC: B32B18/00
Filed: 2005-10-28
Abstract: Alumina ceramic is laminated with thin layers (<20µm) aluminum titanate to produce a conch-like (seashell-like) structure that resists fracture. The structure is produced by sequential electrophoretic deposition of layers of alumina (Al2O3) and thin layers of an alumina/titanium/titanium oxide mixture. The deposited laminate is sintered to produce the final product of composite >90% alumina with more than double the toughness of pure alumina. The laminate contains designed compressive stresses due to expansion of the titanium on oxidation and further expansion when it reacts with local alumina to form aluminum titanate Al2 TiO5. These compressive stresses deflect propagating cracks on interception. The magnitude of the internal stresses can be controlled via the alumina:titanium:titanium oxide ratio used thus enabling production of alumina ceramics with designed toughness.
