Ceramic articles with increased surface roughness and methods for manufacturing the same

Patent Number: 9387057

Patent Date: 2016-07-12

Patent type: utility

Disclosed herein is a ceramic article with an increased surface roughness. The ceramic article includes a ceramic body having an engagement surface and a composite porous layer disposed on the engagement surface of the ceramic body. The composite porous layer is formed from a material including multiple first ceramic particles and multiple second ceramic particles. The sintering temperature of the first ceramic particle is lower than the melting temperature of the second ceramic particle, and at least some of the second ceramic particles are disperse within the composite porous layer whereby increasing the surface roughness of the ceramic article. Methods for manufacturing such ceramic article are also disclosed.
