摘要
研究表明，通过直接激光沉积，VT6/Ta/Zr 合金可形成多孔材料，用于生物医学应用。改变激光功率可以获得孔隙率可变的合金。选择的模式可形成具有与人体骨骼相应的正常弹性模量的多孔材料。结果发现，在激光功率为 50 W 时，孔隙率值可达到 32%，符合牙科修复等方面的要求。在直接激光沉积具有可变孔隙率的 VT6/Ta/Zr 合金材料的过程中，钽颗粒不会熔化，而是充当结晶中心。这种条件可确保形成高度分散的金属结构，主要由 VT6 粉末和均匀分布的 Ta 和 Zr 颗粒组成。
Study of structure and properties of a new porous composite material obtained by direct laser deposition
The possibility of formation of porous materials for biomedical applications from VT6/Ta/Zr alloy by direct laser deposition has been shown. Varying the laser power allowed to obtain alloys with variable porosity. The modes providing formation of porous material with normal elasticity modulus corresponding to human bone were selected. It was found that the porosity value of 32% is achieved at the laser power of 50 W, which meets the requirements, for example, for dental prosthetics. In the process of direct laser deposition of materials in VT6/Ta/Zr alloys with variable porosity tantalum particles do not melt and act as crystallization centers. Such conditions ensure the formation of a highly dispersed metal structure consisting mainly of VT6 powders with evenly distributed Ta and Zr particles.
