Abstract: Fusion is an effective method of creation periodic y-Al2O3 nanostructures on a-Al2O3 surface. For this purpose laser radiation is used with density of capacity 10^5-10^6 W/cm2 by means of pulse radiation or scanning by a laser beam on a surface. The ceramics surface treatment is made using both continuous and pulse lasers based on YAG+Nd type «LTN-102» and «Quantum-12». It is shown, that the form and the size of formed periodic nanostructures depends on both direction and speed of current melt, and grains orientation on which there is a process of melt solidification.
Keywords: aluminum oxide ceramics, laser processing, periodic surface nanotexturing
