The Layer by Layer Selective Laser Synthesis of Ruby

摘要

In the work, features of the layer-by-layer selective laser synthesis (SLS) of ruby from an Al_2O_3–Cr_2O_3 mixture are considered depending on the irradiation power, the laser beam traverse speed, the height and amount of the backfill of powder layers. It has been established that, under irradiation, a track consisting of polycrystalline textured ruby forms. The morphology of the surface of the track and its crystalline structure are determined by the irradiation conditions.
