Enhanced Thermal Shock Resistance of Ceramics through Biomimetically Inspired Nanofins

open access: yes, 2010
We propose here a new method to make ceramics insensitive to thermal shock up to their melting temperature. In this method the surface of ceramics was biomimetically roughened into nanofinned surface that creates a thin air layer enveloping the surface ...
