The modification of ceramic surfaces by directional laser melting is interesting because it can eliminate surface defects and thus improve the ceramics mechanical performance, as long as one prevents the formation of cracks. The feasibility of surface modification by laser assisted melting on large tZrO 2 Al 2 O 3 eutectic ceramic pieces was evaluated in this work. 0.4 mm thick, defect free, resolidified layers were obtained on plates of 40 mm width by preheating at 1200 ºC and processing at 1000 mm/h with a lineshaped
