Аннотация

The structure and morphology of pellets from nanoscale hydroxyapatite after CO 2 laser beam treatment are studied. It is shown that the use of a compacted layer of the material under treatment allows a significant reduction of the diameter of the laser spot. The effects of scanning speed and density of a hydroxyapatite pellet on the structure and morphology of the treated surface are investigated. It is shown that the congruent melting of the material is observed in the case of the high speed of laser beam movement. A decrease in the speed leads to the transition to sintering mode. The optimal values of the density and thickness of the sintered material are determined, which are to be kept during 3D printing of products from hydroxyapatite by means of selective laser melting.
