摘要： Complex-shaped, ceramic-metal composite articles are prepared by: a) contacting a non-wettable powder that is non-wetting and non-reactive to a metal to be used for infiltration with a shaped ceramic body having a removable portion not present in said article to form a layer of the non-wettable powder covering the surface of the shaped ceramic body except for said removable portion, wherein the shaped ceramic body is comprised of a ceramic which is reactive with the metal under the conditions of step (b); b) infiltrating the shaped ceramic body with the metal through said removable portion, where there is no layer of the non-wettable powder, such that a complex-shaped ceramic-metal composite comprising one or more metal phases and one or more ceramic phases is formed, wherein undesirable regions of excess metal on the surface and undesirable phases within the complex-shaped ceramic-metal composite article near the surface are located only in said removable portion; and (c) removing said removable portion, whereby the article has substantially the net shape of the shaped ceramic body without said portion.

摘要： A non-wetting and non-reactive layer of a non-wettable powder formed on part, but not all, of the surface of a shaped ceramic body limits infiltration of metal to the region(s) where there is no layer of the non-wettable powder and thereby limits the formation of undesirable regions of excess metal on the surface of, and undesirable phases near the surface within, the resultant ceramic-metal composite article .

摘要： Complex-shaped, ceramic-metal composite articles are prepared by:

a) contacting a non-wettable powder that is non-wetting and non-reactive to a metal to be used for infiltration with a shaped ceramic body having a removable portion not present in said article to form a layer of the non-wettable powder covering the surface of the shaped ceramic body except for said removable portion, wherein the shaped ceramic body is comprised of a ceramic which is reactive with the metal under the conditions of step (b);
b) infiltrating the shaped ceramic body with the metal through said removable portion, where there is no layer of the non-wettable powder, such that a complex-shaped ceramic-metal composite comprising one or more metal phases and one or more ceramic phases is formed, wherein undesirable regions of excess metal on the surface and undesirable phases within the complex-shaped ceramic-metal composite article near the surface are located only in said removable portion; and
(c) removing said removable portion, whereby the article has substantially the net shape of the shaped ceramic body without said portion.
