METHOD OF COATING COMPLEX-SHAPED CERAMIC-METAL COMPOSITES AND THE PRODUCTS PRODUCED THEREBY

摘要

The invention is a process for preparing a coated ceramic-metal composite article with few or no defects in its surface(s), comprising: (a) forming a first smoothing layer(s) on one or more face(s) of a shaped ceramic-metal composite article; and (b) further forming a plating layer on the first smoothing layer(s) on one or more face(s) of the shaped ceramic-metal composite, such that a coated ceramic-metal composite article comprising one or more metal phases and one or more ceramic phases is formed, wherein the article has no defects in the plating layer. The invention is also a coated ceramic-metal composite article with a first smoothing layer(s) and a plating layer on the first smoothing layer on one or more face(s) of the ceramic-metal composite article with no defects of more than 100 micrometers on the surface of the article. The process of the invention allows the preparation of a coated ceramic-metal composite article with no defects on the surface(s) of the article after the coating process. A coated ceramic-metal composite article is prepared which contains no defects on the surface(s) of the article after the coating process.
