摘要
A novel route to simple processing of an in-situ layered and graded alumina/calcium-hexaluminate (CA(6)) composite is described. The processing involves partial infiltration of a porous alumina preform with hydrolysed calcium acetate to yield a homogeneous layer of alumina and a heterogeneous graded layer of CA(6)/alumina. The homogeneous layer is designed to provide strength, hardness, and wear resistance, while the graded layer is tailored to impart toughness and damage tolerance. The effect of CA(6) on the physical and graded characteristics is discussed. (C) 1998 Elsevier Science Limited. All rights reserved.
