In this research, a surface texturing technique is applied on fine ceramic parts. An objective of this research is a technology development to achieve high-efficient flow of a solid-liquid two-phase flow in small gap between the parts. The solid-liquid two-phase flow has small solid particles of micrometers order in diameter in the liquid. As a surface texturing method, a laser was applied as a texturing tool because the laser processing independent on the strength of the material and the small laser spot is suitable to complete fine texturing on the fine ceramic parts. In the present paper, fundamental examination under various laser conditions was carried out. The effects of laser irradiation conditions on processing shape and size were investigated.
