Abstract: The system may include a rotatable stage configured to support a ceramic substrate and an energy emitter positioned adjacent to the ceramic substrate. In some cases, the energy emitter may be configured to transmit an energy beam toward one or more outer faces of the ceramic substrate so as to modify a surface roughness of the one or more outer faces. In some cases, the method may include identifying a target surface roughness based at least in part on a target friction coefficient, and identifying a target surface area of the ceramic substrate, transmitting an energy beam toward the surface of the ceramic substrate via an energy emitter positioned adjacent to the ceramic substrate, and heating the target surface area of the surface of the ceramic substrate until a surface roughness of the target surface area is within a predetermined range of the target surface roughness.

Abstract: A non-contact method of characterizing the isostatic strength of a ceramic member or article includes capturing a digital image of the ceramic article, and then forming a two-dimensional representation of the ceramic article and the web therein based on the captured digital image. The method also includes performing finite-element analysis on the two-dimensional representation of the ceramic article using a select amount of simulated isostatic pressure to determine a maximum stress value within the two-dimensional representation of the web. The method further includes using the maximum stress value to characterize the isostatic strength of the ceramic article.
