Method of preparing complex-shaped ceramic-metal composite articles and the products produced thereby

摘要

The invention is a complex-shaped article, comprising an article prepared by joining at least one multi-phase ceramic-metal part and at least one shaped part of another material, wherein the theoretical density of the at least one ceramic-metal part is greater than 80 percent. In another aspect, the invention is a process for preparing complex-shaped articles, comprising: (a) forming at least one ceramic-metal part; (b) forming at least one shaped part of another material; and (c) joining the at least one shaped ceramic-metal part with the at least one shaped part of another material such that a complex-shaped article is formed. The invention is a less costly and time-consuming process for preparing complex-shaped composite articles wherein the articles are formed of two or more selected materials wherein one of the materials is a ceramic-metal composite.
