DEGRADATION OF ALUMINA PARTICLES UNDER SELECTIVE LASER MELTING CONDITIONS
摘要
In modern technologies, attention is drawn to the possibility of synthesizing composites from multicomponent mixtures in which there are conditions for the formation of a finely dispersed structure. However, under the conditions of 3D technologies, the mutual influence of the components and the special melting and crystallization conditions leads to the fact that the composition of the synthesis products is poorly predictable in advance. In this work, the selective laser melting (SLM) method was used to form a three-dimensional sample 5 × 5 × 2 mm in size, a composite of interpenetrating phases of different elemental compositions based on titanium. The alumina is absent in the synthesis products due to nonequilibrium conditions that accelerate diffusion processes that limit the dissolution of the oxide.
