摘要：

The technology of selective laser melting is used to conduct the basic experimental study on Al2O3 powders and slurry. The experimental results show that the forming effect of Al2O3 powder is worser, and in contrast that of Al2O3 slurry is better. Laser power has important impact on the surface quality of Al2O3 slurry samples, and the surface quality continuously upgrades with the increment of laser power. With the laser power of 200 W and scanning speed of 90 mm/s, the average Vickers hardness of Al2O3 sample is about 14.7 GPa. © 2016, Chinese Lasers Press. All right reserved.
