Processing and characterization of laser-sintered Al2O3/ZrO2/SiO2

In this study, bioceramics of alumina, zirconia, and silica were synthesized through Nd:YAG laser sintering process aiming at studying the microstructure and phase composition based on the various laser processing parameters used. Optimal parameters of scanning speed and average laser power for selective laser sintering were determined. Effect of shifting of consecutive single vector on the process of forming the monolayer was also studied. Following the synthesis, the structure and composition were characterized by scanning electron microscopy and analyzing X-ray diffraction. The results help understand the characteristics of the laser-sintered composite ceramic formed and suggested more applications in the biomedical fields in future.
